Acid-Base Balance Lab (2D)

Interactive 2D Davenport diagram: drive pCO2 (respiratory) and plasma HCO3- (metabolic) with sliders and watch the Henderson-Hasselbalch equation classify blood pH as normal, acidosis or alkalosis in real time.

Medical Technology & Imaging Physics2DEasy60 FPS📱 Mobile-adapted⇄ 3D version

This 2D companion simulator draws a live Davenport diagram — plasma HCO3- on the vertical axis, pH on the horizontal axis, with diagonal iso-pCO2 lines — and drives it from two real physiological controls: pCO2 (the respiratory component, set by the lungs) and plasma HCO3- (the metabolic component, set by the kidneys). The Henderson-Hasselbalch equation converts both into a live blood pH, which is classified as normal, respiratory acidosis, respiratory alkalosis, metabolic acidosis or metabolic alkalosis as you move the sliders. Toggle physiological compensation on or off to see how the kidneys or lungs partially correct a primary disorder by adjusting the other variable, pulling the point back toward the normal zone on the diagram.

⚙ Under the hood

Interactive 2D Davenport diagram where adjustable pCO2 and plasma HCO3- drive the Henderson-Hasselbalch equation, with live pH classification and compensation modeling.
