The mean Sat 10 was 94.7% +/- 1.6%. The mean Sat 50 was 96.5% +/- 1.5%. There was no relationship between any of the O2 Sat measures and sex, race, or obesity as measured by body mass index. However, older subjects ( 60 years of age) had lower Sat 10 (92.8 +/- 2.3) and Sat 50 (95.1 +/- 2.0) than did younger subjects. O2 flux = (cardiac output x (Hemoglobin concentration x SpO2 x 1.34) + (PaO2 x 0.003)) – oxygen consumption. SvO2 = mixed venous oxygen saturation; measured via a sample of blood from a pulmonary artery catheter (PAC) measures the end result of O2 consumption and delivery; is used in ICU as a measure of O2 extraction by the body; normal SvO2.

Q:
What are the normal oxygen saturation levels by age?

A:
For infants and children, the normal oxygen saturation level should range between 97% to 99%.

For adults less than 70 years of age, the normal oxygen saturation level should range between 96% to 98%.

For adults aged 70 and above, the normal oxygen saturation level should be greater than 94%.
