Assessment of the Thorax and Lungs, Cardiovascular & Peripheral Vascular Systems Diagnostic Reasoning for Advanced Practice Nursing FNP 431 2014 Crystal A. Smith, MSN, APN, CNP A & P Thorax and Lungs Note: each interspace is numbered by the rib above it. Ribs 1-7 articulate to the sternum. Ribs 8-10 articulate to the costal cartilage just above them. Ribs 11-12 “float” with no anterior articulation. The 11th rib tip can be felt laterally and the 12th rib Felt posteriorly. Note the costal angle usually 90 degrease at xiphoid, with chronic overinflation angle increases as with emphysema. A & P Thorax and Lungs Reference lines help us to pinpoint findings, describe findings, and be aware of underlying anatomy. Also use reference of Anterior and Posterior Axillary lines and the Midsternal line (dotted lines). Anterior View I I I I I I I I I Lateral View I I I I I I I I I Posterior View A & P Thorax and Lungs Notes ◦ The left lung has no middle lobe. ◦ The anterior chest contains mostly upper and middle lobe with very little lower lobe. ◦ The posterior chest contains almost all lower lobe. ◦ Primary muscle-diaphragm Secondary muscles include scalenes and parasternals Accessory muscles are used in exercise and with certain diseases-the sternomastoids, the scalenes, and the abdominal muscles assist and are much more visible. A & P Thorax and Lungs The Pleurae is the thin (few millimeters) envelope of slippery lubricating fluid between the lungs and the chest wall. It has a vacuum (negative pressure) and holds the lungs tightly against the chest wall which allows for ease of smooth respirations. The Trachea and the Bronchi transport gasses between the environment and the lung parenchyma. protect the lungs by screening the air for environmental particulates and secreting mucus that entraps the particles via the goblet cells that line the bronchi. A & P Thorax and Lungs A & P Thorax and Lungs Posterior View of Fields A & P Thorax and Lungs Lateral View of Fields A & P Thorax and Lungs Radiograph Thorax and Lungs Interviewing/Health Hx/Causes Common Symptoms ◦ ◦ ◦ ◦ ◦ Chest Pain Dyspnea and dyspnea on exertion Wheezing Cough Hemoptysis Initially open ended questions, then clarify issue more and ask more specific questions. OLD CART the issue. Thorax and Lungs Interviewing/Health Hx/Causes Chest Pain-tease out cardiac vs thorax and lung. Lung tissue has no pain fibers BUT ◦ an inflammatory process with the parietal pleura from pulmonary infarction or pneumonia causes pain. ◦ A muscle strain supporting the lung parenchyma causes pain. ◦ An inflammatory process from anxiety or tachycardia from anxiety causes pain. Thorax and Lungs Interviewing/Health Hx/Causes Dyspnea ◦ Awareness that effort of breathing inappropriate. ◦ Occurs in chronic lung disease like COPD, cystic fibrosis, and asthma. ◦ Make every effort to determine severity of dyspnea based on the patient’s daily activities COPD-“Have you had to stop going upstairs to do laundry because of being short of breath?” Anxious or tachycardic cause-dyspnea is usually explained by inability to “get a deep or good breath” often associated paresthesias around the lips or in the extremities. Thorax and Lungs Interviewing/Health Hx/Causes ◦ Wheezing Musical respiratory sounds that are often audible to the patient and others. Occur because of an obstruction in the airway due to inflammation as in asthma, secretions, or a foreign body. ◦ Cough Reflex response to irritants in the larynx, trachea, or large bronchi. Internal irritants-mucus, blood, mucus, and puss External irritants-dust, foreign bodies, and hot or cold air. Thorax and Lungs Interviewing/Health History Cough continued-Causes ◦ ◦ ◦ ◦ ◦ infection-viral URI being most common cause. Inflammation of the parenchyma Inflammation from a tumor or TB Enlarged parabronchial lymph * Cardiovascular causes-left ventricular heart failure ◦ Esophageal causes-reflux ◦ Postnasal drip ◦ Chronic bronchitis Thorax and Lungs Interviewing/Health History *Hilar Thorax and Lungs Interviewing/Health Hx/Causes Questions to ask regarding the cough ◦ Duration Acute-lasting less than 3 weeks URI most commonly, asthma, foreign body, acute bronchitis, left sided heart failure Subacute-lasting 3-8 weeks Postinfection cough-reactive airway, bacterial sinusitis, asthma Chronic-lasting more than 8 weeks Postnasal drip, asthma, chronic bronchitis, bronchiectasis Thorax and Lungs Interviewing/Health Hx/Causes Is the cough dry or productive? If productive ◦ ◦ ◦ ◦ Sputum volume Color Consistency Odor Other questions to ask: ◦ ◦ ◦ ◦ ◦ ◦ Fever CP Dyspnea Orthopnea Change in ADL’s to accommodate wheezing Thorax and Lungs Interviewing/Health Hx/Causes Large volume-lung abscess, CF or any bronchiectasis Mucoid sputum is clear, white, or grey Purulent sputum is yellow or green Hemoptysis rare in children, common with CF, cause may be post nasal, lung, or stomach (darker) Malodorous-anaerobic lung abscess or to some extent any bacterial process Thorax and Lungs Interviewing/Health Hx/Causes Asking about smoking-calculate smoking pack-years: ◦ –Divide the number of cigarettes smoked per day by 20 (the number of cigarettes in a pack) ◦ –Then multiply by the number of years smoked (70cigarettes/day ÷20 cigarettes/pack) X 10years = 35pack-years (35cigarettes/day ÷20 cigarettes/pack) X 20years = 35pack-years (10cigarettes/day ÷20 cigarettes/pack) X 35years = 17.5pack-years (10cigarettes/day for 10 years and 30 cigarettes a day for 15 years)=10cig ÷ 20poss x 10years= 5 pack years; 30cig ÷ 20poss x 15 years=22.5 pack years+ 5 pack years = 27.5 pack years in total. Thorax and Lungs Interviewing/Health Hx/Causes Knowing ABC’s A=Airway (midline, patent B = Bones (fractures, lytic lesions) C = Cardiac Silhouette size (should be less than 50%) D = Diaphragm (flat or elevated hemidiaphragm?)

Techniques of Exam Palpation ◦ Tender areas and visible abnormalities ◦ Test chest expansion (excursion) Place thumbs at level of 10th ribs, fingers loosly grasping and parallel to the lateral rib cage Slide them medially just enough to raise a loose fold of skin along the spine Tell patient “take a nice deep breath” and watch the distance between thumbs as they move apart with inspiration Unilateral decrease found with CF, pleural effusion, lobar pneumonia, pleural pain Techniques of Exam Palpation ◦ Feel for tactile fremitus (vibrations transmitted through the bronchopulmonary tree-have the patient say “ninety-nine” as you palpate with the ulnar surface of your hand. ◦ Fremitus more prominent interscap and lower lungs (pg. 308 Daines) ◦ Note increased, decreased, or absent fremitus. Fremitus decreased or absent when the voice is high pitched or soft, in a person with a thick chest wall, with an obstructed bronchus, COPD, pleural effusion, CF, pneumothorax, or tumor Fremitus increased with pneumonia from the increased transmission of sound through consolidated tissue. Techniques of Exam Anterior and Posterior areas for Tactile fremitus Techniques of Exam Percussion ◦ Hyperextending the 3rd digit of the hand and press the DIP firmly on the surface to be percussed avoiding any other surface contact by the hand. With a striking motion and relaxed wrist strike the DIP with the tip of the other hands 3rd digit. Move briskly. ◦ Resonance is NORMAL Techniques of Exam ◦ Percussion abnormals Dullness replaces resonance when fluid or solid tissue replaces air Lobar pneumonia when alveoli have fluid and blood in them Pleural accumulation of fluid as with pleural effusion Blood-hemothorax, pus-empyema Fibrous tissue or tumor Flatness heard with large fluid mass Hyperresonance heard Hyperinflated lungs of COPD or asthma- excessive air Large pneumothorax Tympany-high, hollow, drum like sound heard over the stomach usually-in the lungs indicates a pneumothorax Techniques of Exam Areas for Percussion and Auscultation Techniques of Exam Auscultation ◦ Vesicular or soft and low pitched heard through inspiration, continue without pause through expiration, and then fade away about one third of the way through expiration. Heard over most of the lung fields ◦ Bronchovesicular inspiratory and expiratory sounds equal Heard over the 1st and 2nd intercostal spaces anteriroly and between the scaps posteriorly. ◦ Bronchial-louder, harsher and hight in pitch, with a short silence between inspiration and expiration sounds. Expiration longer. Heard over the manubrium ◦ Tracheal-inspiratory and expiratory sounds are equal Very loud over the trachea in the neck Techniques of Exam Auscultation continued http://www.practicalclinicalskills.com/lungsounds.aspx Nonmusical or discontinuous ◦ Crackles (generally high-pitched, discontinuous sounds) Coarse: loud, low-pitched sounds Fine: soft, high-pitched sounds ◦ Pleural friction rubs (grating sound) Musical or continuous ◦ Wheezes high-pitched sounds that are musical in quality ◦ Rhonchi low pitched with a “snoring” or “gurgling” quality ◦ Stridors sounds heard over the trachea Techniques of Exam Techniques of Exam Any time that the spoken word is louder with auscultation think-consolidation Any time with wheezing-think narrowed airways-asthma, allergic reaction, emphesema Any time there is tracheal deviation, inability to breath well with CP think- pneumothorax Any time cough associated with febrile illness and exam shows consolidation thinkpneumonia and check chest x-ray See table 8-7 in Daines, pgs 330-331 Techniques of Exam A and P of the CV system Provide to tissues ◦ oxygen, nutrients, hormones, vitamins Gets rid of from tissues ◦ heat, CO2, nitrates, water Closed system ◦ Interconnected organs and tubing (easy to add fluid) ◦ Difficult to get rid of extra fluid - must depend on the kidneys A and P of the CV system 2-sided pump ◦ Left side works harder than right side ◦ Left side is under more pressure ◦ Atria contraction responsible for 25% of ventricular filling ◦ Right ventricle occupies most of the anterior cardiac surface ◦ The “base of the heart” refers to the superior aspect of the heart at the right and left 2nd interspace next to the sternum. A and P of the CV system Blood pathway Superior/Inferior Vena Cavas → RA → Tricuspid→ RV → Pulmonic valve → Lungs → Pulmonary vein → LA → Mitral valve → LV → aortic valve → Body Note: Pulmonary vein is the only vein to carry oxygenated blood. A and P of the CV system The right side of the heart collects venous blood and pumps it to the lungs via the pulmonary artery; the blood returns via four pulmonary veins to the left atrium, then it is pumped from the left ventricle to the body. Events happen simultaneously on the right and left side. Heart Sounds “Noises” (heart sounds) due to closure of valves (healthy valves make no noise when opening) Opening “snaps” = usually bad valve Lubb Dubb Lubb S1 →→→ S2 →→→ S1 →→→ ↓ ↓ S3 S4 ↓ ↓ Closing of Mitral Aortic Valves Tricuspid Pulmonic MT Dubb S2 AP Left valves (M and A) are under the most pressure Heart Sounds S1 ◦ synchronous with the carotid (So if not sure of which sound is S1, feel for carotid at the same time) Splitting of S1 ◦ mitral under more pressure, more likely to close first. No clinical significance. Heart Sounds Split S2 = aortic closes first (“Lubb-spit”) = physiological splitting (more common than paradoxical) due to more pressure in left side Heart Sounds Paradoxical splitting of S2 (“opposite”) = pulmonic valve closes first (still sounds like “Lubb-spit”). ◦ When patient blows air out, physiological split stops due to change in the intrathoracic pressure/blood flow. ◦ The paradoxical splitting will not stop (can’t be “blown away”). ◦ Then take deep breath in and split S2 goes away = Paradoxical splitting ◦ Causes: Left bundle branch block (LBBB) Aortic stenosis (having trouble closing, common in elderly) Heart Sounds Fixed splitting S2: Can’t get it to go away with inspiration, expiration, turning, or moving ◦ Causes: Atrial -Septal Defect (ASD) - more common in women Previously: as patients aged with ASD, they had pulmonary hypertension and enlarged hearts, and usually died by 60. Now: often fixed before having any symptoms Heart Sounds S3 = ventricular gallop secondary to ventricle “shuddering” ◦ Ventricle is being overworked, but tries to give one more push of blood out. Ken - tuc - ky Lubb - dubb - dubb (S3) S3 = normal in children In adults, S3 means CHF!!! Heart Sounds S4 = atrial gallop, made by atria giving one more “umph” (push) to push blood out ◦ Usually by the time S4 appears, atria are not in too good of shape ◦ Difficult to hear Tenn - ess – ee Lubb-lubb-dubb (S4) May have S4 in: post-MI hyperthyroidism aortic stenosis (very common in the elderly - valve worn out; pt. faints from blood not getting to brain, has carotid bruits) Most common cause: chronic hypertension (whether treated or not) Heart Sounds S3 more serious than S4 Summation gallop ◦ a combination S3, S4 (both present) ◦ atrial contraction superimposed on ventricular filling Hear splits best in pulmonic area Hear S3, S4, S1 best at apex Heart Sounds “Silences” are also important: Lubb Dubb S1 S2 S3 Systole Lubb S1 S4 Diastole -------One Cardiac Cycle------S3 and S4 occur during diastole. Dubb S2 Heart Sounds Systolic murmurs involves S1, S2 Some are pathologic Diastolic murmurs - all are pathologic “Bad things happen in the diastolic phase”. Tap out the “Lubb-Dubb” with your fingers ◦ If there is a noise between Lubb and Dubb = systolic sound ◦ If there is a noise after Dubb = diastolic sound Interviewing/Health Hx/Causes Chief Issues ◦ ◦ ◦ ◦ ◦ Chest pain Palpitations Shortness of breath (PND) Edema Syncope History of present illness ◦ OLDCART Interviewing/Health Hx/Causes Review of systems Past medical history Inquire about any raised blood pressure, heart problems, fainting, dizziness or shortness of breath. Any heart attacks, any history of angina, any cardiac procedures or operations (type and date of intervention and outcome)? Previous levels of lipids if ever checked or known. Any history of rheumatic fever or heart problems as a child? General: any other operations or illnesses, especially history of myocardial infarction, hyperlipidaemia, hypertension, strokes, diabetes? Interviewing/Health Hx/Causes Family history ◦ Ask about hypertension, ischaemic heart disease, strokes, diabetes, hyperlipidaemia, congenital heart disease, early deaths (before the age of 60) in the family. Social/Personal history Lifestyle and Risk Factors ◦ Smoking ◦ Obesity: calculate body mass index (BMI); acute weight increase may indicate fluid retention and heart failure. ◦ Diet: healthy or unhealthy. ◦ Employment: sedentary? Stress? ◦ Home life: stress? Change of ADL’s to accommodate issue? ◦ Recreation and exercise Interviewing/Health Hx/Causes Other questions one might explore: ◦ Dyspnea on exertion is the most common type of dyspnea and may precede other evidence of heart failure. ◦ Orthopnea: does the patient have to sleep propped up at night, and if so with how may pillows? ◦ Edema? Asking about tight rings, shoes, belts Interviewing/Health Hx/Causes Continued-Other questions to explore ◦ Any paroxysmal nocturnal dyspnea or breathlessness at rest? These may last from minutes to hours and be accompanied by wheezing, sweating, distress, and cough with frothy or bloodstained sputum. This is commonly termed “cardiac asthma.” ◦ Cheyne-Stokes or periodic breathing: this often occurs during sleep, with a long cycle time, and may be found in chronic pulmonary edema or poor cardiac output. Interviewing/Health Hx/Causes Continued-Other questions to explore Palpitations-do not necessarily indicate any underlying cardiac pathology but may be presentation of a cardiac arrhythmia. ◦ Description may be bumping, throbbing, or thumping. ◦ Duration: sudden short episodes suggest paroxysmal tachycardia; longer duration with irregularities suggests atrial dysrhythmia. ◦ Associated symptoms: pain, dyspnea, feeling faint or syncope. Interviewing/Health Hx/Causes Other history to explore ◦ Drugs/medication: prescribed, over-thecounter, or illegal drug abuse. ◦ Associated cough: Duration, paroxysms or constant, dry or productive?
