CORRECT WELL DETAILED
Aerobic metabolism - ANSWER Metabolism that can proceed only in the presence of
oxygen.
Agonal gasps - ANSWER occasional, gasping breaths that occur after the heart has
stopped
Alveolar minute volume - ANSWER The volume of air moved through the lungs in 1
minute minus the dead space; calculated by multiplying tidal volume (minus dead space)
and respiratory rate.
Alveolar ventilation - ANSWER The volume of air that reaches the alveoli. It is
determined by subtracting the amount of dead space air from the tidal volume.
American Standard System - ANSWER A safety system for large oxygen cylinders,
designed to prevent the accidental attachment of a regulator to a cylinder containing the
wrong type of gas.
Anaerobic metabolism - ANSWER The metabolism that takes place in the absence of
oxygen; the principle product is lactic acid.
Apnea - ANSWER absence of spontaneous breathing
Aspiration - ANSWER In the context of airway, the introduction of vomitus or other
foreign material into the lungs.
1
, Ataxic respirations - ANSWER Irregular, ineffective respirations that may or may not
have an identifiable pattern.
Automatic transport ventilator (ATV) - ANSWER A 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 A device with a 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.
Capnography - ANSWER A noninvasive method to quickly and efficiently provide
information on a patient's ventilatory status, circulation, and metabolism; effectively
measures the concentration of carbon dioxide in expired air over time.
Capnometry - ANSWER A device that measures the amount of expired carbon dioxide.
Carina - ANSWER Point at which the trachea bifurcates (divides) into the left and right
mainstem bronchi.
