Confusion (neuro)
Coma
hyperkalemia
Cardiac arrest
Hyperkalemia, hypoxemia, and acidosis can cause what?-
ANSWER-MI
Coma can be caused by what?-ANSWER-An increased CO2
level and hydrogen causes dilated cerebral blood vessels
which increases blood flow to the brain and causes cerebral
edema and cause decreased CNS response.
COPD medulla responds to what?
What should you be careful of?-ANSWER-COPD patients
medulla is used to increased CO2 and responds to CO2 levels
so when you put oxygen on they may stop breathing.
