Ch 15 Airway Management Flashcards
Name the anatomical structures of the upper airway that are above the glottis.
tongue, uvula, pharynx, (nasopharynx, oropharynx, laryngopharynx), epiglottis
Name the anatomical structures of the lower airway that are below the glottis.
larynx, vocal cords, trachea
The physical act of moving air in to and out of the lungs
ventilation
The process of loading oxygen molecules onto hemoglobin molecules in the bloodstream
oxygenation
The exchange of oxygen and carbon dioxide in the alveoli and the tissues of the body
respiration
The process of exchanging oxygen and carbon dioxide between the alveoli and the blood in the pulmonary capillaries
external respiration (pulmonary respiration)
The exchange of oxygen and carbon dioxide between the systemic circulation and the cells of the body
internal respiration (cellular respiration)
The amount of air that is moved into or out of the lungs during a single breath
tidal volume
respiratory rate X tidal volume =
minute volume
Pulling of air into the lungs with negative intrathoracic pressure
negative pressure ventilation
normal breathing
Forcing of air into the lungs
positive pressure ventilation
created with a bag-mask device, pocket face mask or mechanical ventilation device
The amount of air that moves in and out of the lungs per minute minus the dead space
minute volume
A low level of oxygen in arterial blood
hypoxemia
can often be reversed by administering supplemental oxygen
A deficiency of oxygen at the tissue and cellular levels
hypoxia
requires more aggressive oxygenation and in some cases, ventilatory support
Partial pressure of carbon dioxide
PaCO2
