6
Q
When do you use Winters formula?
A
when a pt has metabolic acidosis and you want to know the expected pCO2 response
[1.5(HCO3)] + 8 +/- 2
7
Q
What is the Winters formula?
A
[1.5(HCO3)] + 8 +/- 2
8
Q
What is the delta gap equation?
A
Change in AG/ change in HCO3
9
Q
How do you determine if a pt with metabolic alkalosis has PCO2 compensating as expected?
A
0.7(change in HCO3 from normal) + 40
