ABG's Flashcards
normal pH
7.35-7.45
normal PaCO2
35-45
normal HCO3
22-26
normal oxygenation
80-100
mild hypoxemia
70-79
moderate hypoxemia
60-69
severe hypoxemia
<60
what is the buffer system
first line of defense
when is the buffer system activated
within seconds
when is the respiratory system activated
several hours
when does the renal system activate
2-3 days
CO2 compensation mechanisms for acidosis
RR and depth will increase
CO2 will be blown off
CO2 compensation mechanisms for alkalosis
RR and depth will decrease
CO2 will be retained
bicarbonate compensation mechanisms for acidosis
H excreted and HCO3 will be retained
Bicarbonate compensation mechanisms for alkalosis
H ions will be retained and HCO3 will be excreted
no compensation
if the value does not match pH is normal - no compensation has taken place
partial compensation
if the value that does not match pH is abnormal and pH is abnormal then partial compensation
full compensation
if the value that does not match the pH is abnormal but the pH is normal then full compensation has occurred
