| Wintersí Formula for Metabolic Acidosis Compensation
Expected pCO2 = 1.5 * HCO3- + 8 +/- 2
Winter's formula is used to
calculate the patients expected
This is then compared with the patients actual (measured) pCO2...
If the measured pCO2
is higher than calculated this indicates Primary Respiratory acidosis.
pCO2 is lower than
calculated this indicates Primary Respiratory acidosis.
If the values are
similar then Respiratory compensation is deemed adequate.
