Hemoglobin's S-shaped curve lets blood grab oxygen in the lungs and release it in tissues. The cooperative binding (Hill coefficient > 1) makes the curve steep, so a small pressure drop unloads a lot of O₂. A right shift (higher P50) releases even more where it's needed. Educational tool, not medical advice.

Saturation here75.1%

At lungs (100 mmHg)97%

At tissue (40 mmHg)75%

Governing equation

S = \frac{( p O _{2} ) ^{2.7}}{26. 6 ^{2.7} + ( p O _{2} ) ^{2.7}} = 0.75

Reading this result: Cooperative binding (Hill 2.7) gives the S-shape: the swing from 40 to 100 mmHg moves saturation from 75% to 97%, which is how tissues get their O₂.
