Venous Blood pH Calculator: Determine Acid-Base Balance

Calculate Your Venous Blood pH

Easily calculate venous blood pH using bicarbonate (HCO3-) and pCO2 values. This online tool helps medical professionals assess acid-base status, identifying potential acidosis or alkalosis for patient care. Fast, accurate, and essential for monitoring metabolic and respiratory conditions.

Formula:

The Venous Blood pH is estimated using a modified Henderson-Hasselbalch equation:

`pH = 6.1 + log10([HCO3-] / (0.03 × pCO2))`

  • pH: Calculated Venous Blood pH
  • [HCO3-]: Bicarbonate concentration (mEq/L)
  • pCO2: Partial pressure of carbon dioxide (mmHg)
  • 6.1: pKa of the bicarbonate buffer system at 37°C
  • 0.03: Solubility coefficient of CO2 in plasma at 37°C (mmol/L/mmHg)
