Oxygen saturation can miss a large a a gradient.
Oxygen saturation at room temperature.
For example someone older than 70 years of age may have an oxygen saturation level of about 95 which is an acceptable level.
Normal arterial blood oxygen saturation levels in humans are 95 100 percent.
This results in 20 oxygen dissolution from air compared to pure oxygen.
If the level is below 90 percent it is considered low and called hypoxemia.
Dissolved oxygen meters by entering feet above sea level or in some meters an internal barometer compensates for changes in pressure automatically provided that the barometer is properly calibrated.
Normal pao2 on fio2 100 should be 500 mmhg.
Normally dissolved oxygen from air in fresh water and sea water salt water at pressures ranging 1 4 bar abs are indicated in the diagrams and tables below.
The normal oxygen saturation level is 97 100 oer 1.
Dissolved oxygen values shown in the table represent saturation for the corresponding temperature.
Oxygen solubility in fresh and salt water chart pdf.
Oxygen saturation can be 100 when pao2 is 90 mmhg or 300 mmhg.
Older adults typically have lower oxygen saturation levels than younger adults.
In aquatic environments oxygen saturation is a ratio of the concentration of dissolved oxygen o 2 to the maximum amount of oxygen that will dissolve in that water body at the temperature and pressure which constitute stable equilibrium conditions well aerated water such as a fast moving stream without oxygen producers or consumers is 100 saturated.
Oxygen saturation under ideal conditions is 2.
In air with normal composition the oxygen partial pressure is 20 of the total pressure.
