What is the standard pulse oximeter reading expected at sea level?

A pulse oximeter is a non-invasive device used to measure the oxygen saturation level in a person's blood. At sea level, the standard expected reading for a healthy individual typically ranges between 95% and 100%. The value of 98% is often cited as the average or ideal saturation for individuals at sea level, indicating that the bloodstream is carrying a sufficient amount of oxygen to the body’s tissues.

This measurement reflects how effectively oxygen is being transported from the lungs to the rest of the body and is crucial for overall health. A reading of 98% suggests that there is an adequate supply of oxygen being delivered, which is necessary for optimal cellular function and metabolism. Hence, 98% is the most appropriate representation of a healthy oxygen saturation level at sea level.
