UCLA EMT Airway Unit Exam
Questions and Answers 100% Pass
Ventilation - ✔✔The physical act of moving air into and out of the lungs
Oxygenation - ✔✔The process of loading oxygen molecules onto
hemoglobin molecules in the bloodstrean.
Respiration - ✔✔the actual exchange of oxygen and carbon dioxide in the
alveoli as well as the tissues of the body
tidal volume - ✔✔The amount of air (in mL) that is moved in or out of the
lungs during one breath.
Residual Volume (RV) - ✔✔The air that remains in the lungs after maximal
expiration.
Alveolar ventilation (VA) - ✔✔The volume of air that reaches the alveoli;
calculated by subtracting the amount of dead space air from tidal volume.

,Minute Volume - ✔✔The Volume of air moved through the lungs in 1 min.
Calculate by multiplying TV and RR
Alveolar Minute Volume - ✔✔The Volume of air moved through the lungs
in 1 min minus the dead apace.
Vital Capacity (VC) - ✔✔The amount of air that can be forcibly expelled
from the lungs after breathing in as deeply as possible.
Dead space - ✔✔The portion of the tidal volume that does not reach the
alveoli and thus does not participate in gas exchange.
Hypoxia - ✔✔Low oxygen saturation of the body, not enough oxygen in
the blood
Dyspnea - ✔✔difficult breathing,labored breathing, shortness of breath.
Surfactant - ✔✔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 - ✔✔Respiration that requires oxygen

, anaerobic respiration - ✔✔Respiration in the absence of oxygen. This
produces lactic acid.
Diffusion - ✔✔the process by which molecules move from an area of
higher concentration to an area of lower concentration
hypercarbia - ✔✔Increased carbon dioxide level in the bloodstream.
tension pneumothorax - ✔✔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 - ✔✔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 - ✔✔blood in the pleural cavity
open pneumothorax (sucking chest wound) - ✔✔An open or penetrating
chest wall wound through which air passes during inspiration and
expiration, creating a sucking sound.
