Best Answer

Normal oxygen saturation levels vary slightly depending on age and activity. A blood oxygen level of less than 90 percent is considered abnormal. The organs in the body need a continuous supply of oxygen to function properly. If oxygen saturation levels in the body become too low, various problems can develop. When oxygen saturation is too low it is called Hypoxemia.

What is normal saturation?

"Oxygen saturation" refers to the fraction of hemoglobin that is saturated by oxygen. It is related to the partial pressure of oxygen in the inspired air and, therefore, to altitude. Normal oxygen saturation in an otherwise healthy individual at sea level is > 95%. Low oxygen saturations can be found in a wide variety of lung diseases.

Why 1g of Hb bind to 1.34ml of Oxygen instead 1.39 at full saturation?

1g of Hb can bind with 1.34mL of oxygen instead 1.39 at full saturation because it does so at normal oxygen capacity.


What is the normal oxygen saturation of the left ventricle?

Deoxygenated blood from pulmonary circulation and cardiac perfusion is dumped into the the left atria, which brings down the oxygen saturation to about 97%. This is referred to as physiological shunting.

Is oxygen saturation of 91-95 acceptable with a collapsed lung?

Yes. Oxygen Saturation should be above or equal to 95 percent in a normal adult (without a collapsed lung), so between 91-95 is acceptable.
