Q

why can’t a person with COPD breathe with normal O2 levels?

A

copd pts have chronically elevated CO2 levels, and the chemoreceptors for CO2 do not respond to the high CO2 levels. therefore their stimulus for oxygen MUST be low (<95%)

Q

the body compensates for low O2 levels by __ and __

A

tachycardia (speeding up heart rate); chronic hypoxia (developing secondary polycythemia due to low O2 in the kidneys, which stimulates the release of erythropietin)
