Flashcards in Airway Management Deck (17):
the passageway by which air enters or leaves the body. the structures of the airway are the nose, mouth, pharynx, larynx, trachea, bronchi, and lungs
an airway (passage from nose or mouth to lungs) that is open and clear and will remain open and clear, without interference to the passage of air into and out of the body.
the contraction of smooth muscle that lines the bronchial passages that results in a decreased internal diameter of the airway and increased resistance to air flow.
a high pitched sound generated from partially obstructed air flow in the upper airway
breathing in and out (inhalation and exhalation), or artifical provision of breaths
the amount of air that reaches the alveoli
the exchange of oxygen and carbon dioxide between the alveoli and circulating blood in teh pulmonary capillaries
the exchange of oxygen and carbon dioxide between cells and circulating blood
the diffusion of oxygen and carbon dioxide between the alveoli and the blood (pulmonary respiration) and between the blood and the cells (cellular respiration). Also used to mean, simply breathing
an insufficiency of oxygen in the body's tissues
increased work of breathing; a sensation of shortness of breath
the reduction of breathing to the point where oxygen intake is not sufficient to support life.
when breathing completely stops
a blue or gray color resulting from lack of oxygen in the body
pressure applies to the cricoid ring to minimize air entry into the esophagus during positive pressure ventilation also called Sellick Maneuver
a permanent surgical opening in the neck through which the patient breaths
