Oxygenation

abnormal breath sounds heard over the lungs

small air sacs at the end of the terminal bronchioles that are the site of gas exchange

incomplete expansion or collapsed of a part of the lungs

upper chambers of the heart

slow rate of breathing

those heard over the trachea; high in pitch and intensity, with expiration being longer than inspiration

medication that relaxes contractions of smooth muscles of the bronchioles

normal breath sounds heard over the upper anterior chest and intercoastal area

microscopic hair-like projections that propel mucus toward the upper airway so that it can be expectorated

fine crackling sounds made as air moves through wet secretions in the lungs

tendency of solutes to move freely throughout a solvent from an area of higher concentration to an area of lower concentration until equilibrium is established

types of breath-activated delivery methods for inhaled medication

difficult or labored breathing

polyvinyl-chloride airway that is inserted through the nose or the mouth into the trachea, using a laryngoscope as a guide

act of breathing out; synonym is exhalation

blood that develops in the pleural space

condition in which there is more than the normal amount of air entering and leaving lungs

decreased rate or depth of air movement into the lungs

deficient oxygenation of blood

inadequate amount of oxygen available to the cells

act of breathing in; synonym is inhalation

exchange of oxygen and carbon dioxide between the circulating blood and the tissue cells

instrument that delivers a controlled dose of medication to narrowed airways with each compression of the canister

disposable, plastic device that delivers oxygen via two protruding prongs for insertion into the nostrils

instrument that disperses fine particles of medication into the deeper passages of the respiratory tract where absorption occurs

process by which oxygenated blood passes through body tissues

fluid in the pleural space

continuous, dry grating sound caused by inflammation of pleural surfaces and loss of lubricating pleural fluid

air in the pleural space

movement of air into and out of the lungs

noninvasive technique that measures the oxygen saturation of arterial blood

gas exchange between the atmospheric air in the alveoli and blood in the capillaries

instrument used to measure lung capacities and volumes; one type is used to encourage deep breathing (incentive spirometry)

respiratory secretion expelled by coughing or clearing the throat

detergent-like phospholipid that reduces surface tension of the fluid lining the alveoli

rapid rate of breathing

aspiration of fluid or air from the pleural space

artificial opening made into the trachea through which a tracheostomy tube is inserted

lower chambers of the heart

normal sound of respirations heard on auscultation over peripheral lung areas

continuous, high-pitched squeak or musical sound made as air moves through narrowed or partially obstructed airway passages
