oxygen Flashcards
wheeze/continuous
prominent on expiration, high pitched,musical quality
rhonchi/continuous
low pitched, inspiration, expiration
vescicular
soft breezy, heard over most lung tissue, louder longer inspiration
bronchovesicular
each side of sternum, area of thorax clavicle, equal duration and intensity. normal major airways.
bronchial
heard over trachea, blowing quality, longer and louder expiration
crackles.discontinous
fine middle to late inspiration soft, high pitched, coughing does not clear short duration,found lower lung fields
crackles, discontinous
early inspiration, louder, slightly lower pitched longer duration, any area of lung
ventilation
process of moving gases into and out of lungs
Perfusion
ability of cardiovascular system pump oxygenated blood to tissue and return deoxygenated blood to the lungs.
tissue oxygenation
physiological, developmental, lifestyle, enviromental
neural
CNS control of respiratory rate, depth and rhythm cerebral cortex regulates voluntary control of resp by delivering umpulses to the resp motor neurons by way of spinal cord.
Chemical
Maintains appropriate rate and depthof resp based on changes in CO2 O2 H concentration Ph in blood.
tidal volume
Volume inhaled or exhaled per breath
Residual volume
Air left in lungs after a maximal exhalation
Functional Residual Exhalation
Volume of air left in lungs after a normal exhalation
