QUESTIONS AND CORRECT DETAILED ANSWERS (VERIFIED
ANSWERS) |ALREADY GRADED A+
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
Bronchioles - CORRECT ANSWER-Subdivision of the smaller bronchi in the lungs;
made of smooth muscle and dilate or constrict in response to various stimuli
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
Copnography - CORRECT 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 - 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 needs
Compliance - CORRECT ANSWER-Ability of the alveoli to expand when air is drawn
in during inhalation
Continous Positive airway pressure (CPAP) - CORRECT 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 - CORRECT ANSWER-portion of the tidal volume that does not reach
the alveoli and thus does not participate in gas exchange
Diffusion - CORRECT ANSWER-process in which molecules move from an area of
higher concentration to an area of lower concentration
dyspnea - CORRECT ANSWER-shortness of breath
end-tidal - CORRECT ANSWER-the amount of CO2 present at the end of an exhaled
breath
