Acidosis Compensation
 

Metabolic Acidosis Compensation: Winters' Formula

PaCO2 = [(1.5*HCO3) + 8] ± 2

 

PaCO2=arterial part press CO2

 

Assesses adequacy of compensation for metabolic acidosis

 

If calculated PaCO2 = actual PaCO2 , then compensation adequate.

 

If actual > calculated , then both met and resp acidosis present.

 

If actual < calculated , then met acidosis & resp alkalosis present.
