Q
What is the equation for calculating whether or not a patient is compensated adequately for metabolic acidosis?
A
PaCO2 = 1.5(HCO3) + 8 +/- 2
2
Q
What is the equation for calculating whether or not a patient is compensated adequately for metabolic alkalosis?
A
Expected change in PaCO2 = (.5 to 1.0) change in HCO3
3
Q
What are the equations for calculating whether or not respiratory acidosis is acute or not?
A
Acute:
HCO3 = 24 + (PaCO2 - 40)/10
Chronic:
HCO3 = 24 + 4(PaCO2 - 40)/10
4
Q
What is the equation for calculating anion gap?
A
Anion gap = [Na] - ([Cl] + [HCO3])
5
Q
What are the equations for calculating whether or not respiratory alkalosis is acute or not?
A
Acute
Expected HCO3 = 24 - 2(40 - PaCO2)/10
Chronic:
Expected HCO3 = 24 - 5(40 - PaCO2)/10
