Use our free Blood pH Calculator to quickly determine your blood's acid-base balance. Input bicarbonate (HCO3) and PaCO2 values to assess if you have acidosis, alkalosis, or a normal pH level. This tool is vital for understanding your physiological state.
Formula:
The Blood pH Calculator utilizes a simplified form of the Henderson-Hasselbalch equation:
pH = 6.1 + log10 ( [HCO3-] / (0.03 * PaCO2) )
Where:
- pH: The resulting blood pH value.
- 6.1: The pKa of the bicarbonate buffer system in human plasma.
- [HCO3-]: Bicarbonate concentration, measured in milliequivalents per liter (mEq/L).
- PaCO2: Partial pressure of carbon dioxide, measured in millimeters of mercury (mmHg).
- 0.03: The solubility coefficient of CO2 in plasma.
