EMT Airway Exam Guide 2025 With
Questions and Answers
Capnometry - CORRECT ANSWER-A device that measures the amount of expired CO2, capnometer
Carina - CORRECT ANSWER-point at which the trachea bifurcates into the left and right mainstem
bronchi
Chemoreceptors - CORRECT ANSWER-monitor the levels of O2, CO2, and the pH of the cerbrospinal fluid
and then provide feed back to the resp. centers to modify the rate and depth of breathing based on the
body's need
Aerobic Metabolism - CORRECT ANSWER-Metabolism that can proceed only in the presence of oxygen
Agonal gasps - CORRECT ANSWER-Occasional, gasping breaths that occur agter the heart has stopped
Airway - CORRECT ANSWER-The upper airway tract or the passage above the larynx, which include the
nose, mouth and throat.
, Alveolar Minute Volume - CORRECT ANSWER-The volume of air moved through the lungs in 1 minute
minus dead space; calculated by multiplying the tidal volume and resp. rate
Alveolar Ventilation - CORRECT ANSWER-Volume of air that reaches the alveoli. It is determined by
subtracting the amount of dead space air from the tidal volume
American Standard Safety System - CORRECT ANSWER-A safety system for large oxygen cylinders,
designed to prevent the accidental attachment of regulator to a cylinder containing the wrong type of
gas.
Anaerobic Metabolism - CORRECT ANSWER-metabolism that takes place in the absence of oxygen;
principle by product is lactic acid.
Apnea - CORRECT ANSWER-absence of spontaneous breathing
Aspirations - CORRECT ANSWER-the introduction of vomitus or other foreign material into the lungs
Ataxic Respirations - CORRECT ANSWER-Irregular, ineffective respirations that may or may not have an
identifiable pattern
Automatic Transport Ventilator (ATV) - CORRECT ANSWER-Ventilation device attached to a control box
that allows the variables of ventilation to be set. It frees the EMT to perform other tasks while the
patient is being ventilated
Bag-valve Mask (BVM) - CORRECT ANSWER-device with one way valve and a face mask attached to a
ventilation bag; when attached to a reservoir and connected to oxygen, it delivers more than 90%
supplemental oxygen
Barrier device - CORRECT ANSWER-a protective item such as a pocket mask with a valve, that limits
exposure to a patient's body fluids
Bilateral - CORRECT ANSWER-A body part or condition that appears on both sides of the midline
