med.oxygen-dissociation-Hill Calculator
Calculates oxygen saturation of haemoglobin from partial pressure of O₂ using the Hill equation, generating the oxygen-haemoglobin dissociation curve. The sigmoidal dissociation curve means small changes in PO₂ near the inflection point dramatically shift O₂ delivery — the basis of pulse oximetry interpretation.
Inputs
Po2 Mmhg
Force per unit area (Pa). Atmospheric pressure at sea level: 101,325 Pa. Check whether gauge or absolute pressure is required.
P50 Mmhg
Reference formula or conversion factor shown for context.
N Hill
Reference formula or conversion factor shown for context.
Hb G Dl
Amount of solute per unit volume. Higher concentration = more solute dissolved.
Results
oxygen saturation SO₂ (%)
How close the system is to its capacity limit. Above 80% sustained saturation typically leads to queuing and latency spikes.
O₂ content CaO₂ (mL/dL)
Sample size or count used in the calculation.
SO₂ = PO₂ⁿ/(PO₂ⁿ + P50ⁿ)
Median (50th percentile) latency -- half of requests complete faster than this. Representative of the typical user experience.
Hill coefficient n
Sample size or count used in the calculation.
Bohr effect
Reference formula or conversion factor shown for context.
CaO₂ = 1.34·Hb·SO₂ + 0.0031·PO₂
Reference formula or conversion factor shown for context.
