AAOS 12th Edition ECTSI - Chapter 11
aspiration Correct Ans-in the context of the airway, the introduction of vomitus or other
foreign material into the lungs
ataxic respirations Correct Ans-Irregular, ineffective respirations that may or may not have
an identifiable pattern.
automatic transport ventilator (ATV) Correct Ans-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-mask device Correct Ans-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 Correct Ans-A protective item, such as a pocket mask with a valve, that
limits exposure to a patient's body fluids.
bilateral Correct Ans-A body part or condition that appears on both sides of the midline.
, AAOS 12th Edition ECTSI - Chapter 11
bronchioles Correct Ans-Subdivision of the smaller bronchi in the lungs; made of smooth
muscle and dilate or constrict in response to various stimuli.
capnography Correct Ans-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.
aerobic metabolism Correct Ans-Metabolism that can proceed only in the presence of
oxygen.
aerosol-generating procedure Correct Ans-Any airway manipulation that induces the
production of aerosols that may present a risk for airborne transmission of pathogens, such as
CPR.
agonal gasps Correct Ans-abnormal breathing pattern characterized by slow, gasping
breaths, sometimes seen in patients in cardiac arrest
, AAOS 12th Edition ECTSI - Chapter 11
airway Correct Ans-The upper airway tract or the passage above the larynx, which includes
the nose, mouth, and throat.
alveolar minute volume Correct Ans-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 Correct Ans-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 Safety System Correct Ans-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 Correct Ans-The metabolism that takes place in the absence of
oxygen; the main by-product is lactic acid.
apnea Correct Ans-absence of spontaneous breathing
