Venous Blood pH Calculator

Venous Blood pH Calculator

The venous blood gas calculator estimates the venous blood pH, using the values of bicarbonate (HCO₃) and arterial carbon dioxide partial pressure (PaCO₂) in the patient’s blood. To do so, we apply the Henderson-Hasselbalch equation developed in 1908 by Dr. Lawrence Joseph Henderson and then improved by Dr. Karl Albert Hasselbalch.

If you’d like to estimate arterial blood pH and learn more about it, use our arterial blood pH calculator.
