UCLA EMT Airway Unit UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Ventilation - CORRECT ANSWER - The physical act of moving air into and out of the lungs
Oxygenation - CORRECT ANSWER - The process of loading oxygen molecules onto
hemoglobin molecules in the bloodstrean.
Respiration - CORRECT ANSWER - the actual exchange of oxygen and carbon dioxide in the
alveoli as well as the tissues of the body
tidal volume - CORRECT ANSWER - The amount of air (in mL) that is moved in or out of
the lungs during one breath.
Residual Volume (RV) - CORRECT ANSWER - The air that remains in the lungs after
maximal expiration.
Alveolar ventilation (VA) - CORRECT ANSWER - The volume of air that reaches the alveoli;
calculated by subtracting the amount of dead space air from tidal volume.
Minute Volume - CORRECT ANSWER - The Volume of air moved through the lungs in 1
min. Calculate by multiplying TV and RR
Alveolar Minute Volume - CORRECT ANSWER - The Volume of air moved through the
lungs in 1 min minus the dead apace.
Vital Capacity (VC) - CORRECT ANSWER - The amount of air that can be forcibly expelled
from the lungs after breathing in as deeply as possible.
, Dead space - CORRECT ANSWER - The portion of the tidal volume that does not reach the
alveoli and thus does not participate in gas exchange.
Hypoxia - CORRECT ANSWER - Low oxygen saturation of the body, not enough oxygen in
the blood
Dyspnea - CORRECT ANSWER - difficult breathing,labored breathing, shortness of breath.
Surfactant - CORRECT ANSWER - A liquid protein substance that coats the alveoli in the
lungs, decreases alveolar surface tension, and keeps the alveoli expanded; a low level in a
premature infant contributes to respiratory distress syndrome.
aerobic respiration - CORRECT ANSWER - Respiration that requires oxygen
anaerobic respiration - CORRECT ANSWER - Respiration in the absence of oxygen. This
produces lactic acid.
Diffusion - CORRECT ANSWER - the process by which molecules move from an area of
higher concentration to an area of lower concentration
hypercarbia - CORRECT ANSWER - Increased carbon dioxide level in the bloodstream.
tension pneumothorax - CORRECT ANSWER - An accumulation of air or Gas in the pleural
space that progressively increases pressure in the chest that interferes with cardiac function with
potentially fatal results.
pulmonary embolism - CORRECT ANSWER - A blood clot that breaks off from a large vein
and travels to the blood vessels of the lung, causing obstruction of blood flow.
hemothorax - CORRECT ANSWER - blood in the pleural cavity
