Section 4: Medical Emergencies Chapter 10 Respiratory Emergencies Chapter 10: Respiratory Emergencies Objectives (1 of 2) • List the structure and function of the respiratory system. • State the signs and symptoms of a patient with difficulty breathing. • Describe the emergency medical care of the patient with breathing difficulty. 3 Chapter 10: Respiratory Emergencies Objectives (2 of 2) • Distinguish between the emergency medical care of the infant, child, and adult patient with breathing difficulty. • Describe the special considerations due to high altitude. • Defend OEC treatment regimens for various respiratory emergencies. • Demonstrate the emergency medical care for breathing difficulty. 4 Chapter 10: Respiratory Emergencies Respiratory System 5 Chapter 10: Respiratory Emergencies Anatomy and Function of the Lung 6 Chapter 10: Respiratory Emergencies Characteristics of Poor Breathing • Pulmonary vessels become obstructed. • Alveoli are damaged. • Air passages are obstructed. • Blood flow to the lungs is obstructed. • Pleural space is filled. 7 Chapter 10: Respiratory Emergencies Characteristics of Normal Breathing • Normal rate and depth • Regular breathing pattern • Good breath sounds on both sides of the chest • Equal rise and fall of chest • Movement of the abdomen 8 Chapter 10: Respiratory Emergencies Signs of Abnormal Breathing • Slower than 8 breaths/min or faster than 24 breaths/min • Muscle retractions • Pale or cyanotic skin • Cool, damp (clammy) skin • Shallow or irregular respirations • Pursed lips • Nasal flaring 9 Chapter 10: Respiratory Emergencies Dyspnea • Shortness of breath or difficulty breathing • Patient may not be alert enough to complain of shortness of breath. 10 Chapter 10: Respiratory Emergencies Upper or Lower Airway Infection • Infectious diseases may affect all parts of the airway. • The problem is some form of obstruction to the air flow or the exchange of gases. 11 Chapter 10: Respiratory Emergencies Acute Pulmonary Edema • Fluid build-up in the lungs • Signs and symptoms – Dyspnea – Frothy pink sputum • History of chronic congestive heart failure • Recurrence high 12 Chapter 10: Respiratory Emergencies Chronic Obstructive Pulmonary Disease (COPD) • COPD is the result of direct lung and airway damage from repeated infections or inhalation of toxic agents. • Bronchitis and emphysema are two common types of COPD. • Abnormal breath sounds may be present. – Rhonchi and wheezes 13 Chapter 10: Respiratory Emergencies Spontaneous Pneumothorax • Accumulation of air in the pleural space • Caused by trauma or some medical conditions • Dyspnea and sharp chest pain on one side • Absent or decreased breath sounds on one side 14 Chapter 10: Respiratory Emergencies Asthma or Allergic Reactions • Asthma is an acute spasm of the bronchioles. • Wheezing may be audible without a stethoscope. • An allergen can trigger an asthma attack. • Asthma and anaphylactic reactions can be similar. 15 Chapter 10: Respiratory Emergencies Pleural Effusion • Collection of fluid outside lung • Causes dyspnea • Caused by irritation, infection, or cancer • Decreased breath sounds over region of the chest where fluid has moved the lung away from the chest wall • Eased if patient is sitting up 16 Chapter 10: Respiratory Emergencies Mechanical Obstruction of the Airway • Be prepared to treat quickly. • Obstruction may result from the position of the head, the tongue, aspiration of vomitus, or a foreign body. • Opening the airway with the head tiltchin lift maneuver may solve the problem. 17 Chapter 10: Respiratory Emergencies Pulmonary Embolism • A blood clot that breaks off and circulates through the venous system • Signs and symptoms • Dyspnea • Acute pleuritic pain • Hemoptysis • Cyanosis • Tachypnea • Varying degrees of hypoxia 18 Chapter 10: Respiratory Emergencies Hyperventilation • Overbreathing resulting in a decrease in the level of carbon dioxide • Signs and symptoms –Anxiety –Numbness –A sense of dyspnea despite rapid breathing –Dizziness –Tingling in hands and feet 19 Chapter 10: Respiratory Emergencies Treatment of Dyspnea • Perform initial assessment. • Place the patient on oxygen. • If patient is in respiratory distress, ventilate. • Check pulse. 20 Chapter 10: Respiratory Emergencies Signs and Symptoms (1 of 2) • • • • • • • Difficulty breathing Anxiety or restlessness Decreased respirations Cyanosis Abnormal breath sounds Difficulty speaking Accessory muscles 21 Chapter 10: Respiratory Emergencies Signs and Symptoms (2 of 2) • • • • • • • Altered mental status Coughing Irregular breathing rhythm Tripod position Barrel chest Pale conjunctivae Increased pulse and respirations 22 Chapter 10: Respiratory Emergencies Emergency Medical Care • Give supplemental oxygen at 10 to 15 L/min via nonrebreathing mask. • Patients with longstanding COPD may be started on low-flow oxygen (2 L/min). • Assist with inhaler if available. • Consult medical control. 23 Chapter 10: Respiratory Emergencies Inhaler Medications • Trade names – Proventil – Ventolin – Alupent – Metaprel – Brethine • Generic names – Albuterol – Metaproterenol – Terbutaline 24 Chapter 10: Respiratory Emergencies Prescribed Inhalers • Actions – Relax the muscles surrounding the bronchioles – Enlarge the airways leading to easier passage of air • Side effects – Increased pulse rate – Nervousness – Muscle tremors 25 Chapter 10: Respiratory Emergencies Prior to Administration • Read label carefully. • Verify it has been prescribed by a physician for this patient. • Consult medical control. • Make sure the medication is indicated. • Check for contraindications. 26 Chapter 10: Respiratory Emergencies Contraindications for MDI • Patient unable to help coordinate inhalation • Inhaler not prescribed for patient • No permission from medical control • Maximum dose prescribed has been taken 27 Chapter 10: Respiratory Emergencies Administration of MDI (1 of 3) • Obtain order from medical control or local protocol. • Check for right medication, right patient, right route. • Make sure the patient is alert. • Check the expiration date. • Check how many doses have been taken. 28 Chapter 10: Respiratory Emergencies Administration of MDI (2 of 3) • Make sure inhaler is at room temperature or warmer. • Shake inhaler. • Stop administration of oxygen. • Ask the patient to exhale deeply and put lips around opening. • If the inhaler has a spacer, use it. 29 Chapter 10: Respiratory Emergencies Administration of MDI (3 of 3) • Have the patient depress the inhaler and inhale deeply. • Instruct the patient to hold his or her breath. • Continue administration of oxygen. • Allow the patient to breathe a few times, then repeat dose according to protocol. 30 Chapter 10: Respiratory Emergencies Reassessment • Carefully watch for shortness of breath. • 5 minutes after administration: – Obtain vital signs again. – Perform focused reassessment. • Transport and continue to assess breathing. 31 Chapter 10: Respiratory Emergencies Upper or Lower Airway Infection • Administer warm, humidified oxygen. • Do not attempt to suction the airway or insert an oropharyngeal airway in a patient with suspected epiglottitis. • Transport patient in position of comfort. 32 Chapter 10: Respiratory Emergencies Acute Pulmonary Edema • Administer 100% oxygen. • Suction secretions. • Transport in position of comfort. 33 Chapter 10: Respiratory Emergencies Chronic Obstructive Pulmonary Disease (COPD) • Assist with prescribed inhaler if patient has one. • Transport promptly in position of comfort. 34 Chapter 10: Respiratory Emergencies Spontaneous Pneumothorax • Administer oxygen. • Transport in position of comfort. • Monitor closely. 35 Chapter 10: Respiratory Emergencies Asthma or Allergic Reactions • Obtain history. • Assess vitals signs. • Assist with inhaler if patient has one. • Administer oxygen. • Transport promptly. 36 Chapter 10: Respiratory Emergencies Pleural Effusion • Definitive treatment is performed in a hospital. • Administer oxygen and support measures. • Transport promptly. 37 Chapter 10: Respiratory Emergencies Mechanical Obstruction of the Airway • Clear airway. • Administer oxygen. • Transport promptly. 38 Chapter 10: Respiratory Emergencies Pulmonary Embolism • Administer oxygen. • Place patient in comfortable position, usually sitting. • Assist breathing as necessary. • Keep airway clear. • Transport promptly. 39 Chapter 10: Respiratory Emergencies Hyperventilation • Complete initial assessment and history of the event. • Assume underlying problems. • Do not have patient breathe into a paper bag. • Give oxygen. • Reassure patient and transport. 40
