EMT-B Airway and Breathing Definitionsquestions & correct answers.
Hypoxemia ANS - decreased partial pressure of oxygen in blood
Dyspnea ANS - Shortness of breath or difficulty breathing
Apnea ANS - Absence of breathing; respiratory arrest
Hypoxia ANS - state in which insufficient oxygen is available to meet the oxygen requirements of the
cells
Respiratory Distress ANS - increased respiratory effort resulting from impaired respiratory function
Respiratory Arrest ANS - complete stoppage of breathing
Respiratory Failure ANS - inadequate respiratory rate and/or tidal volume
Pulsus Paradoxus ANS - A drop in BP of more than 10 mmHg during inhalation resulting from increased
pressure in the chest that suppresses the filling of the ventricles of the heart with blood
Wheezing ANS - high-pitched, musical whistling sound that is best heard initially on exhalation;
indicates a lower airway obstruction
Rhonchi ANS - Snoring/rattling noises heard upon auscultation
Crackles ANS - bubbly sounds heard during inhalation
, Pulmonary Embolism ANS - obstruction of blood flow in pulmonary arteries leads to hypoxia because
blood is prevented from flowing to the lung
Pulmonary Edema ANS - excessive fluid collects in spaces between alveoli and capillaries, disturbing
normal gas exchange and leading to hypoxia
Spontaneous Pneumothorax ANS - a pneumothorax (collection of air in the pleural space) that occurs
spontaneously, in the absence of blunt or penetrating trauma.
Epiglottitis ANS - inflammation of epiglottis, compromising airway and respiratory compromis
Pertussis ANS - rapid coughing as body attempts to expel thick mucus from airway
Cystic Fibrosis ANS - overabundant production of thick, sticky mucus, blocking airway and increased
incidence of lung infections
Pneumonia ANS - acute infectious disease, caused by bacterium or a virus that affects lower respiratory
tract causing inflammation and fluid or pus-filled alveoli, leading to poor gas exchange and eventual
hypoxia
Pediatric Patient ANS - respiratory failure most common cause of respiratory arrest and cardiac arrest
Geriatric Patient ANS - respiratory distress can result from any of a number of conditions, dyspnea is a
common complaint
Hypoperfusion (aka SHOCK) ANS - insufficient supply of oxygen and other nutrients to some of the
body's cells that results from inadequate circulation of the blood
Positive Pressure Ventilation ANS - method of aiding a pt whose breathing is inadequate by forcing air
into the lungs (BVM)
