During an ABG, a nurse or lab technician draws blood from an artery, such as the radial artery in the wrist or the femoral artery in the groin. The lower the oxygen level, the more severe the hypoxemia. Anyone who is not achieving the critical blood oxygen saturation level of 90% (SpO2) or of 55-60mmHg (SaO2), may require additional oxygen. The SpO2 test result is expressed as a percentage. Comparison of SpO2 values from different fingers of the hands. However, oxygen saturation below 90% (hypoxemia) is considered low and usually suggests an abnormality in oxygen handling. has decreased. On the other side of the finger, a sensor detects and measures the amount of light that passes through the finger without getting absorbed by the tissue and blood.

For example, someone older than 70 years of age may have an oxygen saturation level of about 95%, which is an acceptable level. In medical shorthand, you may hear it called a PaO2 when using a blood gas and an O2 sat (SpO2) when using a pulse ox. Older adults typically have lower oxygen saturation levels than younger adults. Oxygen saturation is a crucial measure of how well the lungs are working. Normally, a PaO2 reading below 80 mm Hg or a pulse ox (SpO2) below 95 percent is considered low. (2019, July 17). Although it does have a margin of error, a pulse ox reading is usually accurate enough. This can lead to complications in body tissue and organs. Here are a few of them: Such devices have a sensor on a wire attached to the patients finger. Whats more, pulse oximeters can be used continuously and, therefore, can provide long-term monitoring of a persons blood oxygen levels.
