Arterial Blood pH Calculator
- PaCO2 = Arterial oxygen partial pressure
- HCO3 = Bicarbonate
Defination / Uses
The arterial blood pH calculator estimates the acidity of the arterial blood using the Henderson-Hasselbalch equation. Bicarbonate (HCO ₃) and arterial carbon dioxide partial pressure (PaCO ₂) situations are included in the formula developed in 1908 byDr. Lawrence Joseph Henderson and also bettered byDr. Karl Albert Hasselbalch, who amplified it to help with the computation of the arterial blood gas.
Some of the most important information that can be gained from the blood gas values is bloodpH. pH is a measure of acidity or alkalinity of any result. Normal pH value ranges for arterial blood are7.35-7.45, while normal pH of venous blood is7.31-7.41. It means that venous blood is more acidic than arterial. It's due to the fact that there's further of the acidic carbon dioxide (CO₂) in the venous blood.
