What is the Acid Base & How does it work?
Acid‑base balance is essential for maintaining optimal cellular function. The primary regulators are the respiratory system, which controls carbon dioxide (COβ‚‚) elimination, and the renal system, which modulates bicarbonate (HCO₃⁻) reabsorption and excretion. The Henderson‑Hasselbalch equation describes the relationship between pH, arterial COβ‚‚ pressure (PCOβ‚‚) and bicarbonate concentration, allowing clinicians to assess the primary disturbance and the degree of compensation.
pH = pK_a + \log\frac{[HCO_3^-]}{0.03\times P_{CO_2}}
pK_a = 6.1 (acid dissociation constant of carbonic acid)
When the calculated bicarbonate differs from the measured value, the delta (Ξ”) indicates a metabolic component that is not explained by respiratory compensation alone, guiding further diagnostic evaluation.

Frequently Asked Questions
What is the Henderson-Hasselbalch equation?
The Henderson-Hasselbalch equation relates pH, pKa, and the ratio of conjugate base to acid concentrations in a buffer solution.
How does the respiratory system affect acid-base balance?
The respiratory system regulates COβ‚‚ elimination, which directly impacts blood pH by affecting carbonic acid levels.
What role does bicarbonate play in maintaining pH balance?
Bicarbonate (HCO₃⁻) is crucial for buffering acids and maintaining stable blood pH levels.
How do I interpret the results from this calculator?
The calculator provides a pH value and indicates whether there’s an acidosis or alkalosis, along with compensation status.
Can this calculator be used for medical diagnosis?
While helpful, this calculator is a tool for educational purposes. Medical diagnosis should always be done by a healthcare professional.
What are the normal ranges for COβ‚‚ pressure and bicarbonate concentration?
Normal PCOβ‚‚ range is 35-45 mmHg, and HCO₃⁻ concentration is typically 22-29 mEq/L.
How often should I check my acid-base balance?
Regular monitoring depends on your health status; consult with a healthcare provider for personalized advice.
