Lesson Outline Slide # 1 2 3 Objective 24 Instructor Notes A. Baseline Vital Signs and SAMPLE History B. Objectives C. Signs and Symptoms 1. As an Emergency Medical Technician, you must be able to accurately assess and record a patient’s vital signs. You must also know the difference between signs and symptoms. 2. Sign a. A medical or trauma condition of the patient that can be seen, heard, smelled, measured, or felt by the examiner b. Examples 1) Unusual chest movement 2) Bleeding 3) Swelling 4) Pale skin 5) Fast pulse 6) Noisy respirations Because signs can be seen, heard, smelled, measured, or felt, they are considered objective findings. Some of the ways signs (also called clinical findings) can be determined include physical or psychological examination, laboratory tests, and imaging studies (such as X-rays). 4 3. Symptom a. A condition described by the patient b. Examples 1) Shortness of breath 2) Nausea 3) Abdominal pain 4) Chills 5) Chest pain 6) Dizziness Symptoms are subjective findings because they are dependent on (subject to) the patient’s interpretation and description of his complaint. 5 6 Objective 1 D. Vital Signs 1. Vital signs are measurements of breathing, pulse, temperature, pupils, and blood pressure. 2. Measuring vital signs is an important part of patient assessment. 3. Vital signs are measured to: a. Detect changes in normal body function b. Recognize life-threatening situations c. Determine a patient’s response to treatment Copyright 2008, McGraw-Hill 6 Emergency Medical Technician Instructor’s Lesson Plans Slide # 7 Objective 25 Instructor Notes 4. Baseline vital signs are an initial set of vital sign measurements against which later measurements can be compared. a. Watching trends in your patient’s condition is very important. b. With this information and your patient assessment findings, you will be able to recognize life-threatening emergencies, such as shock. Stress to your students the importance of taking two or more sets of vital signs. Explain that doing so will allow them to note changes (trends) in the patient’s condition and response to treatment. For example, after obtaining the first set of vital signs (the baseline), the EMT will be able to spot if the patient’s heart rate is increasing, staying about the same, or decreasing when vital signs are taken a second or third time. 8 9 10 11 5. Equipment. To take a patient’s vital signs, you will need: a. A watch with a second hand or a digital watch that shows seconds. The watch will be used to count your patient’s respirations and pulse as well as to note the time of events for your documentation. b. A penlight or flashlight. This will be used to look at your patient’s pupils. c. A stethoscope. A stethoscope is an instrument used to hear sounds within the body, such as respirations. It is also used to measure blood pressure. d. A sphygmomanometer (blood pressure cuff) to take your patient’s blood pressure. e. A pen and paper to record your findings. E. Pulse 1. Arteries are large blood vessels that carry blood away from the heart to the rest of the body. a. Blood is forced into the arteries when the heart contracts. 2. A pulse is the rhythmic contraction and expansion of the arteries with each beat of the heart. a. A pulse can be felt anywhere an artery passes near the skin surface and can be pressed against firm tissue, such as a bone. 3. Central pulse a. A central pulse is a pulse found close to the body trunk b. Carotid artery 1) Major artery of the neck 2) Supplies the head with blood 3) Pulsations can be found on either side of the neck 4) To find the carotid pulse, place your index and middle fingers in the soft hollow area just to the side of the patient’s windpipe c. Femoral artery 1) Located in the fold between the thigh and pelvis Avoid excess pressure in the elderly patient. Never assess the carotid pulse on both sides at the same time. Assessing both carotid pulses simultaneously can decrease the blood supply to the brain and cause fainting. It can also result in severe slowing of the heart rate because of stimulation of the vagus nerve. Copyright 2008, McGraw-Hill Chapter 5 – Baseline Vital Signs and SAMPLE History 7 Slide # 12 13 Objective 5 Instructor Notes In the field, a femoral pulse is not often used because the patient’s clothing prevents easy access to the femoral artery. To adequately feel a femoral pulse, you may have to apply more pressure than is required at other sites. 4. Peripheral pulse a. A peripheral pulse is located farther from the trunk of the body than a central pulse. b. A peripheral pulse can be felt at several locations: 1) Radial pulse a) Located in the wrist at the base of the thumb b) Check for a radial pulse first when assessing a responsive adult or a child 1 year of age or older c. Brachial pulse 1) Located on the inside of the upper arm, midway between the shoulder and the elbow 2) Always check for a brachial pulse in an infant d. Posterior tibial pulse 1) Located just behind the ankle bone e. Dorsalis pedis pulse 1) Located on the top surface of the foot 5. To feel for a pulse: a. Use the pads of your index and middle fingers, and apply gentle pressure to the artery. b. Count the number of beats for 30 seconds. Then multiply the number by 2 to determine the number of beats per minute. c. If the pulse is irregular, count it for 1 full minute. The pads on the tips of the finger are used because they are the most sensitive areas. Do not use your thumb to assess a pulse – it has a pulse of its own and could be mistaken for the patient’s pulse. If you use too much pressure, you will cut off blood flow through the artery and will not be able to feel a pulse. The posterior tibial and dorsalis pedis pulses may be difficult to feel and/or may not be palpable in well persons. An apical pulse is assessed by listening directly over the heart with a stethoscope. If the pulse rate is irregular, determine the difference between the patient’s apical pulse rate and radial pulse rate. The difference between these measurements is called the pulse deficit. The pulse deficit is an indirect measurement of the heart’s ability to eject sufficient blood into the peripheral circulation with each contraction. Copyright 2008, McGraw-Hill 8 Emergency Medical Technician Instructor’s Lesson Plans Slide # 14 Objectives 6, 7 Instructor Notes 6. Pulse rate and rhythm a. A patient’s pulse rate varies with age and physical condition b. When feeling the pulse, note if the pulse rate is very slow, very fast, or within the normal range for the patient’s age. c. Also, note if the rhythm of the pulse is regular or irregular. 1) An irregular pulse is not constant. 2) A pulse with an irregular rhythm is called a dysrhythmia or arrhythmia. 7. Normal pulse rates at rest Life Stage Newborn Infant Toddler Preschooler School-age child Adolescent Adult Age Birth to 1 month 1 to 12 months 1 to 3 years 4 to 5 years 6 to 12 years 13 to 18 years 18 years and older Beats per Minute 120 to 160 80 to 140 80 to 130 80 to 120 70 to 110 60 to 100 60 to 100 A slow heart rate may be normal in well-conditioned athletes. However, a slow heart rate may occur because of a medical or trauma-related problem. A fast heart rate occurs as a normal response to the body’s demand for more oxygen. In an adult, a rate of less than 60 beats per minute is called bradycardia, and a rate greater than 100 beats per minute is called tachycardia. 15 16 8. Possible causes of a slow heart rate a. Coughing b. Vomiting c. Straining to have a bowel movement d. Heart attack e. Head injury f. Very low body temperature (hypothermia) g. Sleep apnea h. Some medications 9. Possible causes of a rapid heart rate a. Fever b. Fear c. Pain d. Anxiety e. Infection f. Shock g. Exercise h. Heart failure i. Substances such as caffeine and nicotine j. Cocaine, amphetamines, “Ecstasy,” cannabis k. Some medications Copyright 2008, McGraw-Hill Chapter 5 – Baseline Vital Signs and SAMPLE History 9 Slide # 17 Instructor Notes 10. Pulse quality a. Refers to the strength of the heartbeat felt when taking a pulse b. Normal 1) Pulse is easily felt 2) Pressure is equal for each beat 3) “Strong” pulse c. “Weak” = hard to feel d. Weak and fast = “thready” An extremely strong pulse that is difficult to obliterate with pressure is called a "bounding" pulse. A bounding pulse may be felt in patients with fever or high blood pressure (hypertension). A slow, weak pulse may be felt in a patient who is suffering from hypothermia (low body temperature). A thready pulse may be felt in a patient who is hypovolemic. 18 19 20 Objective 2 F. Respirations 1. Respiration is the exchange of gases between a living organism and its environment. a. A single respiration consists of one inhalation and one exhalation. 2. Inspiration (inhalation) is the process of breathing in and moving air into the lungs. 3. Expiration (exhalation) is the process of breathing out and moving air out of the lungs. 4. During inhalation, the chest rises and oxygen is taken into the lungs. During exhalation, the chest falls and carbon dioxide is moved out of the lungs. 5. To count the patient’s respirations: a. Place the patient’s arm across his chest or abdomen. Hold the patient’s wrist as if you are assessing the radial pulse. b. Watch the rise and fall of the chest or abdomen. Begin counting when the chest or abdomen rises. Count each rise and fall of the chest or abdomen as one respiration. c. Watch to see if respirations are regular and if the chest rises equally. Ask the patient not to speak during this time. d. Count respirations for 30 seconds. Multiply the number by 2 to determine the rate for 1 minute. e. If the patient's respirations are irregular or slow, count the rate for 1 full minute. f. In infants and young children, it is often easier to observe the rise and fall of the abdomen to determine the respiratory rate. Count an infant’s respirations for 1 full minute. Do not tell the patient you are counting his respiratory rate. If he knows that it is being assessed, he may vary his breathing without realizing it. Count the patient’s pulse first. When you have finished, keep your hands in place but shift your attention to the patient’s chest and abdomen and count his respiratory rate. Copyright 2008, McGraw-Hill 10 Emergency Medical Technician Instructor’s Lesson Plans Slide # 21 Instructor Notes 6. Normal respiratory rates at rest Life Stage Newborn Infant Toddler Preschooler School-age child Adolescent Adult 22 Objectives 3, 4 Age Birth to 1 month 1 to 12 months 1 to 3 years 4 to 5 years 6 to 12 years 13 to 18 years 18 years and older Breaths per Minute 30 to 50 20 to 40 20 to 30 20 to 30 16 to 30 12 to 20 12 to 20 7. Rhythm of breathing a. Normal respirations are evenly spaced and of adequate depth. b. Infants and young children tend to breathe less regularly than adults do. c. Irregular respirations may be associated with conditions such as a diabetic emergency or head injury. 8. Shallow breathing a. A patient is said to breathe shallowly if it is difficult to see movement of the chest or abdomen during breathing. b. Only a small volume of air is exchanged during shallow breathing. Expansion of the chest may be unequal in conditions involving trauma to the chest, such as fractured ribs, or in certain medical conditions, such as severe pneumonia. Two types of breathing are usually observed. Costal (chest) breathing involves the use of external intercostal muscles and other accessory muscles of breathing (such as the sternocleidomastoid muscles in the neck) and is observed by the movement of the chest upward and outward. Diaphragmatic breathing involves the use of the diaphragm and is observed by the movement of the abdomen. Costal (chest) breathing is common in women. Diaphragmatic (abdominal) breathing is more common in infants, children, and men. 23 9. Labored breathing a. Normal breathing is relaxed and effortless. b. Labored breathing is an increase in the work (effort) of breathing. If a patient is having difficulty breathing, he is usually irritable, anxious, or restless. You may see: 1) Gasping for air 2) Excessive widening of the nostrils with respiration (nasal flaring) 3) Use of muscles in the neck to assist with inhalation 4) Use of the abdominal muscles and muscles between the ribs to assist with exhalation 5) “Sinking in” of the soft tissues between and around the ribs or above the collarbones (retractions) 6) Skin color changes Copyright 2008, McGraw-Hill Chapter 5 – Baseline Vital Signs and SAMPLE History 11 Slide # Instructor Notes The accessory muscles of breathing are used during periods of respiratory distress. This use is particularly common in patients with chronic obstructive pulmonary disease (COPD) and in infants and children. The muscles of the diaphragm and neck are used to assist in inspiration. The muscles of the abdomen and the internal intercostals are used to assist expiration. Nasal flaring is a sign of air hunger. Retractions are suggestive of an obstruction to inspiration in the respiratory tract. The respiratory muscles "sink in" in an effort to overcome the obstruction as the pressure within the pleura becomes increasingly negative. Hyperventilation is rapid, deep breathing that may normally occur because of fear, pain, strenuous exercise, or anxiety. Kussmaul breathing is deep breathing associated with a diabetic emergency. Hypoventilation is shallow breathing that may occur because of narcotic overdose or pain associated with breathing (such as pleurisy, rib fractures). 24 25 26 10. Abnormal respiratory sounds a. Stridor 1) A harsh, high-pitched sound (like the bark of a seal) 2) Associated with severe upper airway obstruction 3) Most often heard during inhalation b. Snoring 1) Results from partial obstruction of the upper airway by the tongue c. Wheezing 1) A high-pitched whistling sound heard on inhalation or exhalation 2) Suggests a narrowed or partially obstructed airway d. Gurgling 1) The sound heard as air passes through moist secretions in the airway e. Crowing 1) A long, high-pitched sound heard on inhalation G. Skin Color, Temperature, and Condition 1. Assessing the patient’s skin condition can provide important information about the flow of blood through the body’s tissues (perfusion). 2. Perfusion is assessed by evaluating: a. Skin color b. Skin temperature c. Skin condition (moist, dry) d. Capillary refill (in infants and children younger than six years of age) Copyright 2008, McGraw-Hill 12 Emergency Medical Technician Instructor’s Lesson Plans Slide # 27 Objectives 8, 9, 10 Instructor Notes 3. Skin color a. Assess the patient's skin color in the nail beds, inside the mouth, and inside the eyelids. b. In infants and children, assess the palms of the hands and the soles of the feet. c. Pale (whitish) skin 1) Occurs when the blood vessels in the skin have severely narrowed (constricted) 2) May be seen in shock, fright, anxiety, and with other causes d. Cyanosis, a blue-gray color of the skin or mucous membranes, suggests inadequate breathing or poor perfusion and often appears first in the fingertips or around the mouth. 1) Cyanosis may be seen in: a) Respiratory distress b) Airway obstruction c) Cold exposure d) Blood vessel disease e) Shock f) Cardiac arrest e. Mottling is an irregular or patchy discoloration of the skin that is usually a mixture of blue and white. 1) Mottled skin is usually seen in patients in shock, with hypothermia, or in cardiac arrest. f. Jaundiced (yellow) skin may be seen in patients with liver or gallbladder problems. g. Flushed (red) skin may be caused by: 1) Heat exposure 2) Late stages of carbon monoxide poisoning 3) Allergic reaction 4) Alcohol abuse 5) High blood pressure Cyanosis is of two types, depending on the level of oxygen in the arterial blood. Central cyanosis is cyanosis of the skin and mucous membranes of the head and trunk and is most readily observed in the oral mucosa and tongue. Peripheral cyanosis is cyanosis of the extremities. Peripheral cyanosis occurs when blood flow to the skin decreases and may be a normal response to a cold environment or anxiety. Cyanosis that appears around the mouth is called circumoral cyanosis. Yellow skin is also associated with an increased intake of vegetables containing high levels of carotene (carotenemia). This type of jaundice is sometimes called pseudojaundice and can be distinguished from true jaundice by the lack of yellow discoloration of the conjunctiva. In carotenemia, the yellow color is noted particularly in the palms, soles, and face. Copyright 2008, McGraw-Hill Chapter 5 – Baseline Vital Signs and SAMPLE History 13 Slide # 28 Objectives 11, 12, 13 Instructor Notes 4. Skin temperature a. Assess skin temperature by placing the back of your hand against the patient's face, neck, or abdomen. b. Normal skin temperature is warm. c. Hot skin may be caused by fever or heat exposure. d. Cool skin may be caused by inadequate circulation or exposure to cold. e. Cold skin may be caused by extreme exposure to cold or shock. f. Clammy (cool and moist) skin may be caused by shock, among many other conditions. 5. Skin condition (moisture) a. Normal skin is dry. b. Wet or moist skin may indicate shock, a heat-related illness, or a diabetic emergency. c. Excessively dry skin may indicate dehydration. The back surfaces of the hands and fingers are used because the skin in these areas is thin and sensitive to temperature changes. It is important to distinguish between generalized and localized coolness and warmth. General coolness can result from conditions such as hypothermia. Localized coolness can result from impaired circulation to a limb. Generalized warmth can result from heat exposure or fever. Localized warmth can occur because of a burn or inflammatory process. In some situations, evaluation of the patient’s skin turgor is important. Skin turgor refers to the elasticity of the skin. To assess skin turgor, gently pinch a small section of skin on the patient’s forearm between your thumb and index finger. (Do not use the back of the patient’s hand to assess skin turgor, because the skin is normally thin and loose in this area.) The skin should quickly spring back to its previous state. If the skin stays pinched or tented or moves back slowly to its previous state, the skin has "poor turgor." Conditions such as dehydration are often associated with poor skin turgor. 29 30 Objective 14 H. Capillary Refill 1. Assess capillary refill in infants and children younger than six years of age. 2. To assess capillary refill, firmly press on the child’s nail bed until it blanches (turns white) and then release. a. Observe the time it takes for the tissue to return to its original color. If the temperature of the environment is warm, color should return within 2 seconds. b. Other sites may be used to assess capillary refill, including the forehead, chest, abdomen, and the fleshy part of the palm. 3. A capillary refill time of 3 to 5 seconds is said to be delayed. This may indicate poor perfusion or exposure to cool temperatures. 4. A capillary refill time of more than 5 seconds is said to be markedly delayed and suggests shock. Capillary refill is most reliable as an indicator of perfusion in infants and children younger than 6 years of age. In adults, other factors may affect capillary refill, such as cold weather, medications, and smoking.

The pupils are normally equal in size, round, and equally reactive to light. 2. Briefly shine a light into the patient’s eyes and assess the size, equality, and reactivity of the patient’s pupils. a. Size 1) Dilated (very big) pupils in the presence of bright light may be caused by trauma, fright, poisoning, eye medications, or glaucoma. 2) Constricted (small) pupils in a darkened area may be caused by narcotics, treatment with eye drops, or a nervous system problem. b. Equality 1) Unequal pupils, a condition called aniscoria, are a normal finding in 2 to 4 percent of the population. 2) In most patients, unequal pupils suggest a head injury, a stroke, the presence of an artificial eye, or cataract surgery on one eye. c. Reactivity 1) Reactivity refers to whether or not the pupils change in response to light. 2) Normally, a light that is shined into the pupil of one eye will cause the pupils of both eyes to constrict. 3) Nonreactive pupils do not change when exposed to light. This condition may occur because of medications or cardiac arrest. 4) Unequally reactive pupils (one pupil reacts but the other does not) may occur because of a head injury or stroke. J. Blood Pressure 1. Blood pressure is the force exerted by the blood on the walls of the arteries. 2. Blood pressure is usually assessed using a blood pressure cuff and stethoscope. This method of taking a blood pressure is called blood pressure by auscultation because it involves the use of a stethoscope. a. When a blood pressure cuff is applied to a patient’s arm and inflated, blood flow in the artery under the cuff is momentarily cut off. b. If a stethoscope is applied over the artery, sounds can be heard that reflect the patient’s blood pressure. As the cuff is slowly deflated, blood flow resumes through the partially compressed artery. 3. The first sound heard is the systolic pressure. Systolic pressure is the pressure in an artery when the heart is pumping blood. 4. As the pressure in the cuff continues to drop, a point is reached where sounds are no longer heard because the artery is no longer compressed. The point at which the sound disappears is the diastolic pressure. Diastolic pressure is the pressure in an artery when the heart is at rest. 5. A blood pressure measurement is made up of both the systolic and the diastolic pressure. a. It is written as a fraction (116/78), with the systolic number first. b. When reporting a blood pressure, the slash is read as "over." For example, a blood pressure of 114/76 would be reported as "114 over 76." I. Copyright 2008, McGraw-Hill Chapter 5 – Baseline Vital Signs and SAMPLE History 15 Slide # Instructor Notes The blood pressure is recorded as an even number because most gauges have a scale marked in increments of 2 millimeters of mercury (mm Hg). If a digital blood pressure device is used, the readings obtained may include both odd and even numbers. It is helpful to record the patient’s position when a blood pressure is recorded because the reading may change, particularly in cases of volume loss (such as dehydration, hemorrhage) when the patient is moved from a supine to a sitting or standing position. Blood pressure readings between the patient's arms may vary by as much as 10 mm Hg. 35 6. Using a stethoscope a. A stethoscope is used to listen to body sounds. b. It consists of four major parts: the chest piece, tubing, binaurals, and earpieces. c. Earpieces 1) Should fit snugly but comfortably in the ears a) For the best sound reception, the earpieces should normally point toward the EMT’s face as the stethoscope is put on. 2) Should be cleaned before and after use d. Binaurals 1) Metal pieces of the stethoscope that connect the earpieces to the plastic or rubber tubing 2) When you are using a stethoscope, the binaurals should be angled so the earpieces remain in the ears without causing discomfort. e. Tubing 1) Should be flexible and 12 to 18 inches in length 2) Longer tubing decreases sound wave transmission. f. Chest piece 1) May consist of a diaphragm and/or bell 2) Diaphragm a) Circular, flat part at the end of the tubing b) Has a thin plastic disk on the end c) Used to detect high-pitched sounds, such as breath sounds 3) Should be firmly held against the patient’s skin with the fingertips of the index and middle fingers g. Bell 1) Some stethoscopes are also equipped with a bell 2) Has a deep, hollow, cuplike shape 3) Used to detect low-pitched sounds such as those heard during blood pressure measurement 4) Should be lightly held against the patient’s skin, just enough to form a seal When possible, the stethoscope should be placed directly on the patient’s skin because clothing makes sounds harder to hear. Copyright 2008, McGraw-Hill 16 Emergency Medical Technician Instructor’s Lesson Plans Slide # 36 Objective 22 Instructor Notes 7. Blood pressure by auscultation a. Step 1. Expose the patient's upper arm. 1) Select the correct size of blood pressure cuff for the patient. 2) Wrap the pressure cuff evenly around the patient's upper arm at least one inch above the elbow. Place the arrow on the cuff over the patient's brachial artery. When taking a blood pressure, it is important to use a blood pressure cuff of the correct size. The width of the cuff should not be more than two-thirds the length of the patient’s upper arm. Blood pressure readings will be wrong if the cuff is the wrong size. 37 38 39 40 41 42 43 44 45 b. Step 2. Locate the patient's radial artery. 1) Rapidly inflate the cuff until you can no longer feel the radial pulse. 2) Inflate the cuff 30 mm Hg beyond the point at which you last felt the pulse. c. Step 3. Place the stethoscope in your ears. 1) Place the diaphragm of the stethoscope over the brachial artery and hold it in place. d. Step 4. While watching the gauge, deflate the cuff slowly and evenly at a rate of 2 to 3 mm Hg per second. 1) Listen for sounds. The first sound is the systolic pressure and should be near the point where the radial pulse disappeared. e. Step 5. Continue to deflate the cuff, noting the point at which the sound disappears. This is the diastolic pressure. f. Step 6. Deflate the cuff completely. 1) Record the blood pressure as systolic/diastolic pressure. 8. Blood pressure by palpation a. Step 1. Expose the patient's upper arm. 1) Select the correct size of blood pressure cuff for the patient. 2) Wrap the pressure cuff evenly around the patient's upper arm at least one inch above the elbow. 3) Place the arrow on the cuff over the patient's brachial artery. b. Step 2. Locate the patient's radial artery. 1) Rapidly inflate the cuff until you can no longer feel the radial pulse. 2) Inflate the cuff 30 mm Hg beyond the point at which you last felt the pulse. c. Step 3. While watching the gauge, deflate the cuff slowly and evenly at a rate of 2 to 3 mm Hg per second. 1) Note the point on the gauge when you feel the return of the radial pulse. This is the systolic pressure and should be near the point where the radial pulse disappeared. d. Step 4. Deflate the cuff completely. Record the blood pressure as systolic/P (for example, 148/P). When a blood pressure is obtained by palpation, the diastolic pressure cannot be measured. Document the patient’s blood pressure as the systolic pressure over a capital “P,” such as 110/P.

Unstable patient a. Assess and record vital signs every 5 minutes 11. Stable patient a. Assess and record vital signs (at a minimum) every 15 minutes 12. Remember: A stable patient can become unstable very quickly. Reassess frequently! K. Additional Vital Signs 1. Pulse oximetry a. Pulse oximetry is a method of measuring the amount of oxygen saturated in the blood. 1) Commonly referred to as pulse ox b. An oximeter is a small machine used to obtain this measurement. c. A small sensor is placed on an area of the patient’s body in which a pulsation can be detected, such as a fingertip or ear lobe. d. The sensor is connected to the oximeter, which is a small computer. The sensor passes red and infrared light waves through the tissue to which it is attached. e. Most of the body’s oxygen is attached to hemoglobin molecules in the arterial blood. 1) Hemoglobin absorbs red and infrared light waves differently when it is bound with oxygen than when it is not. 2) The oximeter calculates the amount of hemoglobin saturated with oxygen. This calculation is called the saturation of peripheral oxygen or SpO2. 3) The oximeter displays this value as a percentage on its screen as well as the patient’s pulse rate. Pulse oximetry is used to detect and provide warnings about low levels of oxygen in the blood. A reading between 96 percent and 100 percent generally indicates adequate oxygenation. A reading between 91 percent and 95 percent suggests a mild lack of oxygen in the tissues (hypoxia). A reading below 91 percent generally indicates severe hypoxia. Supplemental oxygen is usually given to patients whose readings are below 91 percent. Copyright 2008, McGraw-Hill 18 Emergency Medical Technician Instructor’s Lesson Plans Slide # 50 51 Instructor Notes To use a pulse oximeter: 1) Make sure there is no dirt or obstruction on the oximeter’s red light. a) If dirt is present, remove it and clean the device before putting it on the patient. b) Clean the tissue on the patient to which the oximeter will be attached, such as the fingertip or earlobe. c) If the patient’s fingertip is used, remove any dark or metallic nail polish, if present. 2) Attach the pulse oximeter to the patient. a) If the fingertip is used, insert the patient’s finger into the oximeter. Make sure the patient’s tissue is centered over the light and detector. b) Turn the pulse oximeter on. c) To make sure the pulse oximeter’s measurements are accurate, check the patient’s pulse to be sure that the pulse rate shown on the oximeter is consistent with what you feel (palpate) when assessing the patient. g. Indications 1) Altered mental status 2) Respiratory rate outside the normal range for age 3) Increased work of breathing 4) Respiratory or cardiac chief complaints 5) History of respiratory difficulty or respiratory disease 6) During delivery of supplemental oxygen 7) During and after endotracheal intubation 8) During transport of a sick or injured child f. A pulse oximeter measures oxygen saturation. It does not measure the effectiveness of ventilation. Too often, EMS professionals use a pulse oximeter as their only source for determining the patient’s heart rate and oxygen level. Although a pulse oximeter is a useful device, it is not a replacement for patient assessment. 52 53 h. Pulse oximeter readings may be inaccurate in the following circumstances: 1) Poor capillary blood flow 2) Abnormal hemoglobin concentration 3) Abnormal shape of the hemoglobin molecule i. Examples of conditions that may cause these situations, resulting in misleading pulse oximetry readings, include the following: 1) Cardiac arrest 2) Shock 3) Hypothermia 4) Carbon monoxide poisoning 5) Sickle-cell disease 6) Patient movement, shivering 7) Patient use of nail polish 2. End-tidal carbon dioxide (ETCO2) Copyright 2008, McGraw-Hill Chapter 5 – Baseline Vital Signs and SAMPLE History 19 Slide # 54 55 56 Instructor Notes a. Some EMS agencies consider end-tidal carbon dioxide an additional vital sign. b. An end-tidal carbon dioxide detector measures a person’s exhaled carbon dioxide. c. Although an ETCO2 detector is most often used to confirm the position of a tube that has been placed in a patient’s trachea, some detectors can be used with oxygen delivery devices, such as a nasal cannula or bag-mask device. 3. Pain assessment a. Some regulatory agencies consider an assessment of a patient’s pain an additional vital sign. b. EMS and other healthcare professionals often underestimate a patient’s pain. Some of the reasons for this may include the following: 1) Some healthcare professionals believe it is a “waste of time” to ask a patient about her pain. 2) Because pain is unique to the person experiencing it, it is difficult for another person to accurately tell how severe the pain is. 3) The patient may be unable to relay her needs about the pain. c. To assess pain in an adult, ask: “On a scale of 0 to 10, with 0 being the least and 10 being the worst, what number would you give your pain or discomfort?” d. To assess pain in a child three years or older, use the Wong-Baker FACES Pain Rating Scale. 1) This scale shows 6 cartoon faces ranging from a smiling face representing “no hurt” to a tearful, sad face representing “worst hurt.” 2) To use the scale, explain to the child that each picture is a person’s face. a) Face 0 is very happy because he doesn’t hurt at all. b) Face 1 hurts just a little bit. c) Face 2 hurts a little more. d) Face 3 hurts even more. e) Face 4 hurts a whole lot. f) Face 5 hurts as much as you can imagine, although you don't have to be crying to feel this bad. 3) Ask the child to point to the face that best describes how she is feeling. a) Document the number indicated by the child. For example, “Patient rates pain 4 out of 10 on Faces Pain Scale.” b) This is usually simplified when documenting on a prehospital care report to, “Pain 4/10 on FACES Pain Scale.” If the patient is able to express pain, the way in which it is expressed varies. A patient may have tremendous pain, yet show no outward signs of her discomfort. On the other hand, a patient may cry, be very loud and expressive, or revert to childhood behavior when she is in pain.

The patient history is part of the patient assessment during which you find out pertinent facts about the patient’s medical history. b. When possible, ask the patient questions. 1) Try to avoid questions that the patient can answer with a yes or no. 2) Instead, ask questions that will give you as much information as possible, and then allow the patient time to answer. 3) Do not anticipate what the patient is going to say and finish sentences for him. c. In some situations, the patient will not be able to answer your questions. 1) For example, the patient may be unresponsive or too short of breath to provide detailed answers. 2) If the patient is unresponsive, gather as much information as possible by looking at the scene, looking for medical identification tags, and questioning family members, coworkers, or others at the scene. 2. SAMPLE is a memory aid used to remind you of the information that you should get from the patient. a. SAMPLE stands for: 1) Signs and symptoms 2) Allergies a) Find out if the patient has an allergy to medications, food, environmental causes (such as pollen or bees), and products (such as latex). b) Check for a medical identification tag. The patient may be wearing a bracelet or necklace or carrying a wallet card that identifies a serious medical condition, allergies, or medications she is taking. 3) Medications a) Find out if the patient is currently taking any medications. b) You will need to ask specific questions because some patients do not consider some substances medications, such as vitamins or aspirin. 4) (Pertinent) Past medical history a) Ask the patient about medical conditions he may have that may help you determine what the problem is today. b) If the patient is unresponsive, check for a medic alert tag. 5) Last oral intake a) It is important to determine when the patient last ate or had anything to drink. This is especially important if the patient is a diabetic or may need immediate surgery. b) Determine what he last ate or drank, how much he ate or drank, and when. 6) Events leading to the injury or illness a) Ask the patient to tell you what happened. b) This information can provide important clues about the patient’s current situation. Copyright 2008, McGraw-Hill Chapter 5 – Baseline Vital Signs and SAMPLE History 21 Slide # Instructor Notes With medical patients, take the patient’s history before performing the physical exam. With trauma patients, perform the physical exam first. Ask your patient about the frequency with which his symptoms occur. Use this guide to help pinpoint symptom frequency: Constant means 90 to 100 percent of the time. Frequent means about 75 percent of the time. Intermittent means about 50 percent of the time. Occasional means about 25 percent of the time. 61 62 3. OPQRST a. If your patient is complaining of pain, OPQRST is a memory aid that may help identify the type and location of the patient’s complaint. b. Onset: “What were you doing when the problem started?” c. Provocation/Palliation: “What makes the problem better or worse?” d. Quality: “What does the pain feel like (dull, burning, sharp, stabbing, shooting, throbbing, pressure, or tearing)?” e. Region/Radiation: “Where is the pain?” “Is the pain in one area, or does it move?” “Is the pain located in any other area?” f. Severity: “On a scale of 0 to 10, with 0 being the least and 10 being the worst, what number would you assign your pain or discomfort?” g. Time: “How long ago did the problem or discomfort begin?” “Have you ever had this pain before?” “When?” “How long did it last?” M. Questions?

[McGraw-Hill to Insert Figure 5-8 without labels.] Copyright 2008, McGraw-Hill 26 Emergency Medical Technician Instructor’s Lesson Plans Chapter 5 Quiz Answers—Baseline Vital Signs and SAMPLE History Multiple Choice 1. ANS: C Possible causes of a slow heart rate include the following: coughing, vomiting, straining to have a bowel movement, heart attack, head injury, very low body temperature (hypothermia), sleep apnea, and some medications. The other answers listed are more likely to increase heart rate. OBJ: Identify the information obtained when assessing a patient's pulse. 2. ANS: C A normal pulse is easily felt and obliterated by strong pressure, and the pressure is equal for each beat. This kind of pulse is said to be a “strong” pulse. A pulse is said to be “weak” if it is hard to feel. A pulse that is weak and fast is called a “thready” pulse. An extremely strong pulse that is difficult to obliterate with pressure is called a "bounding" pulse. OBJ: Differentiate between a strong, weak, regular, and irregular pulse. 3. ANS: B After selecting the correct size of blood pressure cuff for the patient, wrap the pressure cuff evenly around the patient's upper arm at least one inch above the elbow. OBJ: Describe the methods to assess blood pressure. 4. ANS: A Stridor is a harsh, high-pitched sound (like the bark of a seal). It is associated with severe upper airway obstruction and is most often heard during inhalation. Wheezing is a high-pitched whistling sound heard on inhalation or exhalation that suggests a narrowed or partially obstructed airway. Gurgling is the sound heard as air passes through moist secretions in the airway. Cyanosis is a bluish color of the skin that suggests inadequate breathing or poor perfusion. OBJ: Differentiate between shallow, labored and noisy breathing. 5. ANS: A The radial pulse is located in the wrist at the base of the thumb. Check for a radial pulse first when assessing a responsive adult or a child 1 year of age or older. OBJ: Describe the methods to obtain a pulse rate. 6. ANS: B When determining the quality of a patient's pain or discomfort ask, “What does the pain feel like (dull, burning, sharp, stabbing, shooting, throbbing, pressure, or tearing)?” Copyright 2008, McGraw-Hill Chapter 5 – Baseline Vital Signs and SAMPLE History 27 OBJ: Identify the components of the SAMPLE history. 7. ANS: B The diaphragm is the circular, flat part at the end of the tubing. It has a thin plastic disk on the end. The diaphragm is used to detect high-pitched sounds, such as breath sounds. The binaurals are the metal pieces of the stethoscope that connect the earpieces to the plastic or rubber tubing. Some stethoscopes are equipped with a bell. The bell has a deep, hollow, cuplike shape. It is used to detect low-pitched sounds such as those heard during blood pressure measurement. When possible, the stethoscope should be placed directly on the patient’s skin because clothing makes sounds harder to hear. OBJ: N/A 8. ANS: C A newborn's normal heart rate at rest is 120 to 160 beats per minute. OBJ: Describe the methods to obtain a pulse rate. 9. ANS: D The posterior tibial artery is located just behind the ankle bone. It is used to assess circulation in the lower extremities. OBJ: Describe the methods to obtain a pulse rate. 10. ANS: C Cyanosis is a blue-gray color of the skin or mucous membranes that suggests inadequate oxygenation or poor perfusion. OBJ: Differentiate between pale, blue, red and yellow skin color. Sentence Completion 11. ANS: called gurgling. The sound heard as air passes through moist secretions in the airway is OBJ: Differentiate between shallow, labored and noisy breathing. 12. ANS: Mottling is an irregular or patchy skin discoloration that is usually a mixture of blue and white. OBJ: Identify the normal and abnormal skin colors. Copyright 2008, McGraw-Hill 28 Emergency Medical Technician Instructor’s Lesson Plans Short Answer 13. ANS: Unequal pupils, a condition called aniscoria, are a normal finding in 2 to 4 percent of the population. In most patients, unequal pupils suggest a head injury, a stroke, the presence of an artificial eye, or cataract surgery on one eye. OBJ: Differentiate between reactive and nonreactive pupils and equal and unequal pupils. 14. ANS: The number of respirations per minute can be influenced by many factors. For example, exercise, stress, anxiety, pain, fever, and the use of stimulants can increase the respiratory rate. The use of narcotics or sedatives decreases the respiratory rate. OBJ: Describe the methods to obtain a breathing rate. 15. ANS: Assess a patient's pulse rate, regularity, and quality (strength). OBJ: Identify the information obtained when assessing a patient's pulse. 16. ANS: [McGraw-Hill to Insert Figure 5-8 with labels.] OBJ: Differentiate between dilated (big) and constricted (small) pupil size.
