ventilate and oxygenate the remaining body systems and tissues
airway
passageway by which air enters and leaves the body. includes the nose, mouth, pharynx, larynx, trachea,
bronchi and lungs
alveolar ventilation
the amount of air that reaches the alveoli
artificial ventilation
forcing air or oxygen into the lungs when a patient has stopped breathing or has inadequate breathing
(positive pressure ventilation)
apnea
no breathing
bronchoconstriction
contraction of smooth muscle that lines the bronchial passages that results in a decreased internal
diameter of the airway and increased resistance to airflow
cellular respiration
exchange of oxygen and carbon dioxide between cells and circulating blood
cyanosis
blush color of the skin due to insufficient oxygen levels in the blood
diffusion
process by which molecules move from an area of high concentration to an area of low concentration
dyspnea
difficult or labored breathing; shortness of breath
flail chest
fracture of two or more adjacent ribs in two or more places that allows for free movement of the
fractured segment
flowmeter
valve that indicated the flow of oxygen reaching the tissues of the body
, hypoxia
deficiency of oxygen reaching the tissues of the body
intercostal
situated or extending between the ribs
nasopharyngeal airway
flexible breathing tube inserted through the patient's nostril into the pharynx to help maintain an open
airway
oropharyngeal airway
curved device inserted through the patient's mouth into the pharynx to help maintain an open airway
paradoxical motion
movement of ribs in flail segment that is opposite to the direction of movement of the rest of the chest
cavity
patent airway
airway that is open and clear and will remain open and clear without interference to the passage of air
into and out of the body
pressure regulator
device connected to an oxygen cylinder to reduce pressure, so it is safe for delivery of oxygen to a
patient
pulmonary respiration
exchange of oxygen and carbon dioxide between the alveoli and circulating blood in the pulmonary
capillaries
respiratory arrest
when breathing stops completely
respiratory distress
increased work of breathing; a sensation of shortness of breath (doesn't need ventilation)
respiratory failure
reduction of breathing to the point where oxygen intake is not sufficient enough to support life (needs
ventilation)
retractions
pulling in the skin and soft tissue between the ribs when breathing
upper airway
