responds ONLY to increased BP
aortic arch
transmits via glossapharyngeal nerve to solitary nucleus of medulla
carotid sinus
responds to increase and decrease in BP
carotid sinus
carotid massage effect on HR
decrease
responds to decrease pO2, increase pCO2, and decrease blood pH
peripheral chemoreceptors
-carotid and aortic bodies
respond to changes in pH and pCO2 in brain interstitial fluid
central chemoreceptors
HTN, bradycardia, respiratory depression
cushing triad

increase in ICP --> constricts arterioles
--> cerebral ischemia
--> HTN (sympathetic response)
--> reflex bradycardia
major stimulator of respiration in health people
pCO2
major stimulator of respiration in pts with COPD
hypoxia
--> don't give too much O2!
