The Bohr Effect

Why CO₂ is essential for oxygen delivery

CO₂ Level Normal

Low High

Hemoglobin

Holding O₂ tightly

Low CO₂ → High pH → Strong O₂ binding

Cell Oxygenation

Low O₂ delivery

7.45

Affinity

High

Release

Low

When CO₂ is low, oxygen stays bound to hemoglobin and is not effectively delivered to cells.

Train your breathing. Improve oxygen delivery.
