8
Q
what is the buffer system
A
first line of defense
9
Q
when is the buffer system activated
A
within seconds
10
Q
when is the respiratory system activated
A
several hours
11
Q
when does the renal system activate
A
2-3 days
12
Q
CO2 compensation mechanisms for acidosis
A
RR and depth will increase
CO2 will be blown off
13
Q
CO2 compensation mechanisms for alkalosis
A
RR and depth will decrease
CO2 will be retained
14
Q
bicarbonate compensation mechanisms for acidosis
A
H excreted and HCO3 will be retained
15
Q
Bicarbonate compensation mechanisms for alkalosis
A
H ions will be retained and HCO3 will be excreted
