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.
