Emergency Medical Response You Are the Emergency Medical Responder Your medical emergency response team has been called to the fitness center by building security on a report that an employee complained of having difficulty breathing. You and your partner arrive and find the man conscious but in distress. The patient’s chief complaint is difficulty breathing. He says he just “overdid it” on the treadmill. He appears to be out of breath and is having trouble speaking in full sentences. You begin a primary assessment and determine that the patient is in respiratory distress. Lesson 14: Airway and Ventilation

Emergency Medical Response An Open Airway is the Priority  Ensuring an open airway is the most important step you can take in caring for a patient because a person cannot breathe without an open airway.  A patient who can speak or cry is conscious, has an open airway, is breathing and has a pulse.

Emergency Medical Response Respiratory System Overview  Upper airway tract Begins at the mouth Includes the nose, pharynx and larynx  Lower airway tract Begins below the level of the vocal cords Includes the trachea, bronchi, bronchioles and alveoli

Emergency Medical Response Oxygenation  Oxygenation refers to the amount of oxygen in the bloodstream.  An insufficient amount of oxygen delivered to the cells is referred to as hypoxia.

Emergency Medical Response Types of Respiratory Emergencies  Respiratory distress: when someone has difficulty breathing  Respiratory arrest: the cessation of breathing

Emergency Medical Response Causes of Respiratory Distress  A partially obstructed airway  Illness  Chronic conditions, such as asthma  Electrocution  Heart attack  Injury to the head, chest, lungs or abdomen  Allergic reactions  Drugs  Poisoning  Emotional distress

Emergency Medical Response Signs and Symptoms of Respiratory Emergencies  Slow or rapid breathing  Unusually deep or shallow breathing  Gasping for breath  Wheezing, gurgling or high-pitched noises  Unusually moist or cool skin  Flushed, pale, ashen or bluish skin color  Shortness of breath  Dizziness or light- headedness  Pain in the chest or tingling in the hands, feet or lips  Apprehensive or fearful feelings

Emergency Medical Response Activity You and your partner are summoned to a local conference center in response to an emergency call. A person who was scheduled to speak at a conference began complaining of difficulty breathing about 10 minutes before he was scheduled to speak. On arrival at the scene, you find the patient sitting on the floor, breathing rapidly. The patient states that all of sudden he began to feel dizzy and his lips started tingling.

Emergency Medical Response Specific Respiratory Emergencies  Chronic obstructive pulmonary disease (COPD)  Asthma  Pneumonia  Acute pulmonary edema  Hyperventilation  Pulmonary embolism  Emphysema

Emergency Medical Response Signs of an Open Airway  Chest is rising and falling.  Air is heard and felt coming out of patient’s mouth and nose with exhalation.  The conscious patient is able to speak in full sentences without distress.  The conscious patient is speaking in normal tones.

Emergency Medical Response Signs of an Inadequate Airway  Visibly unable to catch breath  Gasping for air  Abnormal breath sounds Grunting Stridor Snoring

Emergency Medical Response Causes of Airway Obstruction  Mechanical Foreign body o Solid object, such as food, in adults o Large chunks of food and small objects (toy parts or balloons) in children younger than 4 years  Anatomical Tongue Swelling due to trauma, infection, asthma, emphysema or anaphylaxis

Emergency Medical Response Techniques to Clear Airway Obstruction  Abdominal thrusts  Back blows  Chest thrusts  Modified CPR for unconscious patients

Emergency Medical Response Techniques to Remove Foreign Material from the Upper Airway  Finger sweeps Only for an unconscious patient Only when foreign matter is seen in a patient’s mouth Use the index finger for an adult or child and the little finger for a smaller child and an infant  Suctioning

Emergency Medical Response Signs of Inadequate Breathing  Rib muscles pulling in on inhalation  Pursed lip breathing  Nasal flaring  Fatigue or sweating  Excess use of abdominal muscles  Tripod position  Deviated trachea  Abnormal breath sounds (stridor, wheezing, crackles/rales)  Inadequate depth of breathing  Too slow or too rapid rate  Unusual/irregular chest wall movement  Irregular respiratory patterns

Emergency Medical Response Signs of Inadequate Oxygenation  Cyanosis  Pale, cool, clammy skin  Mottling  Altered mental state, such as restlessness, agitation, confusion or anxiety

Emergency Medical Response Artificial Ventilation Methods  Mouth-to-mask  Mouth-to-nose breathing  Mouth-to-stoma breathing  Bag-valve-mask resuscitator (BVM)

Emergency Medical Response BVM Resuscitator Ventilations  Three-part device: a bag, a valve and a mask  Advantages: Increased oxygen blood levels Ability to be connected to emergency oxygen Increased effectiveness of ventilations when used correctly by two rescuers Protection against disease transmission and inhalation hazards Useful with advanced airway adjuncts

Emergency Medical Response BVM Ventilation Rates and Patient Age  30 to 60 breaths per minute: 1 ventilation about every 1 to 2 seconds for a newborn (0 to 1 month)  12 to 20 breaths per minute: 1 ventilation about every 3 seconds for a child or an infant  8 to 10 breaths per minute: 1 ventilation about every 5 seconds for an adult

Emergency Medical Response You Are the Emergency Medical Responder While waiting for emergency medical services personnel to arrive, you complete a SAMPLE history and secondary assessment. You have helped the patient into a position of comfort for breathing when he suddenly loses consciousness and stops breathing. He has a pulse.

Emergency Medical Response Assessing Breath Sounds  Use a stethoscope to listen to lungs In the front, listen along the midclavicular line at the second intercostal space On the sides, listen along the midaxillary line between the fourth and fifth intercostal spaces In the back, listen along the midclavicular line below the scapula  Compare sounds heard on both sides  Suspect obstruction if abnormal sounds, such as wheezing, rales, rhonchi or stridor, are heard

Emergency Medical Response Sellick’s Maneuver  Also known as cricoid pressure  Appropriate during positive pressure ventilation situations when a patient requires intubation  Two rescuers needed: one to perform the maneuver, another to perform the intubation  Application of pressure on both sides of cricoid cartilage using the thumb and index finger, with pressure applied firmly toward the back of the neck

Emergency Medical Response Asthma Medications  Long-term control medications  Quick-relief medications (rescue medications)  Medications for allergy-induced asthma

Emergency Medical Response Asthma Medication Delivery Systems  Metered-dose inhaler  Dry powder inhaler  Small-volume nebulizer  Pill or liquid  Injection

Emergency Medical Response Peak Flow Meter  Measurement of person’s ability to push air out of lungs in one quick breath  Tool for evaluating response to treatment and for warning if asthma is worsening

Emergency Medical Response Common Side Effects of Asthma Medications  Increased heart rate  Palpitations  Nausea or vomiting  Nervousness  Sleepiness  Dry mouth  Cough  Hoarseness  Headache  Throat irritation
