Detailed Verified Answers
Question:Airway
Ans: The passageway by which air enters and leaves the body. The structures
of the airway are the nose, mouth, pharynx, larynx, trachea, bronchi, and
lungs
Question: Alveolar ventilation
Ans: The amount of air that reaches the alveoli
Question: Artificial Ventilation
Ans: Forcing air or oxygen into the lungs when a patient has stopped
breathing or has inadequate breathing. Also called positive pressure
ventilation
Question: Apnea
Ans: Absence of breathing
Question: Bronchoconstruction
, Page | 2
Ans: The contractions of smooth muscle that lines the bronchial passages that
results in a decreased internal diameter of the airway and increased resistance
of airflow.
Question: Cellular Respiration (internal respiration)
Ans: The exchange of oxygen and carbon dioxide b/w cells and circulating
blood
Question: Cyanosis
Ans: A bluish or purplish color of the skin due to insufficient oxygen levels in
the blood
Question: Diffusion
Ans: the process by which molecules move from an area of higher
concentration to an area of lower concentration
Question: Dyspnea
Ans: Difficult or labored breathing; shortness of breath
Question: Flail chest
Ans: fracture of two or more adjacent ribs in two or more places that allows
for free movement of the fractured segment
Question: Flowmeter
, Page | 3
Ans: A valve that indicates the flow of oxygen in liters per minute
Question: Hypoxia
Ans: A deficiency in the amount of oxygen reaching the tissues
Question: Intercostal
Ans: Situated or extending b/w the ribs
Question: Nasopharyngeal airway
Ans: Flexile breathing tube inserted through the patient's nostril into the
pharynx to help maintain an open airway
Question: Oropharyngeal airway
Ans: Curved device inserted through the patient's mouth into the pharynx to
help maintain an open airway
Question: Paradoxical motion
Ans: Movement of the ribs in flail segment that is opposite to the direction of
movement of the rest of the chest cavity
Question: Patent airway
