"WebJul 17, 2024 · A normal oxygen extraction ratio is ~30%. As the amount of oxygen delivered to the body (DO2) decreases, a greater fraction of oxygen will be consumed (higher oxygen extraction ratio). An oxygen extraction ratio >50% is often regarded as reflecting a state of inadequate oxygenation. " - Oxygen extraction tension
