Measuring Oxygen Saturation Is Called

Oxygen saturation should always be above 95 percent.

Measuring oxygen saturation is called.

It is obtained by drawing blood from an artery such as the radial artery in the wrist or the femoral artery in the groin. The properties of the tissue at this point determine the absorption. A level of 92 percent indicates potential hypoxemia or deficiency in oxygen reaching tissues in the body. Normal arterial blood oxygen saturation levels in humans are 95 100 percent.

You can measure the blood s percentage of oxygen saturation using a pulse oximeter a clip like sensor device that is placed on a thin part of your body such as an earlobe or nose. The value obtained from arterial blood gases or abgs sao2 describes the oxygen saturation of arterial blood. A measurement of your blood oxygen is called your oxygen saturation level. Abgs are measured in millimeters of mercury mmhg and can be a clue as to how efficiently your body is exchanging oxygen and carbon dioxide.

The underlying method for measuring oxygen saturation is called photoplethysmography. If the level is below 90 percent it is considered low and called hypoxemia. An oxygen saturation level of 95 percent is considered normal for most healthy individuals. However oxygen saturation may be lower if you have a respiratory disease or congenital heart disease.

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. In this method light of a defined wavelength is shone through a part of the tissue at the measurement site and then measured by a photodetector.
