Venous Blood pH Calculator



Urine Anion Gap


Defination / Uses

The venous blood gas calculator estimates the venous blood pH, using the values of bicarbonate (HCO ₃) and arterial carbon dioxide partial pressure (PaCO ₂) in the case's blood. To do so, we apply the Henderson-Hasselbalch equation developed in 1908 byDr. Lawrence Joseph Henderson and also bettered byDr. Karl Albert Hasselbalch.

The formula developed by Dr. Henderson described the use of carbonic acid as a buffer result. Also,Dr. Hasselbalchre-expressed that formula in a more complicated manner to study acid- base diseases, which redounded in the Henderson – Hasselbalch equation.
