Exam 1, phys CIS Flashcards
which bronchi is more likely to have a foreign body aspiration
right
what is the effect of low CO2 on bronchioles
vasoconstriciton– contracts smooth mm cells
bronchospasms
predisposing factors to sleep apnea
altered sleep position
pharyngeal muscle tone
decreased drive
what is gold standard Dx for obstructive sleep apnea
polysomnography
describe alveolar P and alveolar P in quiet respiration
intrapleural gets more negative during inspiration, less negative during expiration
alveolar pressure gets more negative in inspiration and slightly positive at end of exhalation
how does body compensate for chronic hypozemia
increase epo production
how can pulm HTN and increased Hct change cardiac function so that nocturia occurs
release of ANP
increase Na excretion= diuresis
