EMT AIRWAY EXAM | 2025/2026 UPDATE QUESTIONS
AND ANSWERS | WITH COMPLETE SOLUTION!!
Aerobic Metabolism Answer - Metabolism that can proceed only in the
presence of oxygen
Agonal gasps Answer - Occasional, gasping breaths that occur agter the heart
has stopped
Airway Answer - The upper airway tract or the passage above the larynx, which
include the nose, mouth and throat.
Alveolar Minute Volume 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 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 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 Answer - metabolism that takes place in the absence of
oxygen; principle by product is lactic acid.
,Apnea Answer - absence of spontaneous breathing
Aspirations Answer - the introduction of vomitus or other foreign material into
the lungs
Ataxic Respirations Answer - Irregular, ineffective respirations that may or may
not have an identifiable pattern
Automatic Transport Ventilator (ATV) 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) 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 Answer - a protective item such as a pocket mask with a valve,
that limits exposure to a patient's body fluids
Bilateral Answer - A body part or condition that appears on both sides of the
midline
Bronchioles Answer - Subdivision of the smaller bronchi in the lungs; made of
smooth muscle and dilate or constrict in response to various stimuli
Copnography Answer - a noninvasive method to quickly and efficiently provide
information on a patient's ventilatory status, circulation and metabolism.
Effectively measures the concentration of CO2 in expired over time
, Capnometry Answer - A device that measures the amount of expired CO2,
capnometer
Carina Answer - point at which the trachea bifurcates into the left and right
mainstem bronchi
Chemoreceptors 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 needs
Compliance Answer - Ability of the alveoli to expand when air is drawn in
during inhalation
Continous Positive airway pressure (CPAP) Answer - method of ventilation
used primarily in the treatment of critically ill patients with resp. distress; can
prevent the need for endotracheal intubation
dead space Answer - portion of the tidal volume that does not reach the
alveoli and thus does not participate in gas exchange
Diffusion Answer - process in which molecules move from an area of higher
concentration to an area of lower concentration
dyspnea Answer - shortness of breath
end-tidal Answer - the amount of CO2 present at the end of an exhaled breath
external respiration Answer - the exchange of gases between the lungs and the
blood cells in the pulmonary capillaries; also called pulmonary respiration
