Blood oxygen saturation may be used for hypoxic hypoxia, but is generally meaningless in other forms of hypoxia.
2.
In hypoxic hypoxia 95 100 % saturation is considered normal; 91 94 % is considered mild and 86 90 % moderate.
3.
Oxygen remains at 20.9 % of the total gas mixture, differing from hypoxic hypoxia, where the percentage of oxygen in the air ( or blood ) is decreased.
4.
Even in hypoxic hypoxia blood measures are only an approximate guide; the oxygen level in the brain tissue will depend on how the body deals with the reduced oxygen content of the blood.
5.
These methods can be used to mimic some forms of hypoxic hypoxia and they are currently being studied including the detection of variation in arterial CO 2 tension acting as a quick-response-system for short term ( or emergency ) regulation.
