Oxygen Saturation At Room Temperature

If the level is below 90 percent it is considered low and called hypoxemia.

Oxygen saturation at room temperature. 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. Normal pao2 on fio2 100 should be 500 mmhg. Normal arterial blood oxygen saturation levels in humans are 95 100 percent. Oxygen solubility in fresh and salt water chart pdf.

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 is the fraction of oxygen saturated hemoglobin relative to total hemoglobin unsaturated saturated in the blood the human body requires and regulates a very precise and specific balance of oxygen in the blood. Oxygen saturation can be 100 when pao2 is 90 mmhg or 300 mmhg. At a high fio2 of supplemental oxygen oxygen saturation cannot distinguish a pao2 above 90 mmhg.

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. In air with normal composition the oxygen partial pressure is 20 of the total pressure. The normal oxygen saturation level is 97 100 oer 1. Oxygen saturation under ideal conditions is 2.

Oxygen saturation can miss a large a a gradient. Normal pao2 on fio2 50 should be 250 mmhg linear relationship. This results in 20 oxygen dissolution from air compared to pure oxygen.
