A: Blood oxygen level is measured using pulse oximetry, a noninvasive procedure designed to monitor the delivery of oxygen to peripheral tissue, says Johns Hopkins Medicine. Pulse oximetry uses hemoglobin coloration and blood flow pulsation to measure the blood oxygen level.
Normally, when your blood circulates to your lungs, 95 to 100 percent of your red blood cells are able to grab oxygen molecules, reports Harvard Health Publications. This is the normal oxygen level for an adult female and can be measured using a device known as a pulse oximeter.This is a small instrument that attaches to one of your fingers and is able to measure the amount of oxygen inside your blood in a non-invasive manner.he term oxygen saturation refers to the amount of oxygen your blood is carrying. When your blood circulates, it goes to each of your cells and picks up carbon dioxide, a byproduct of metabolism.
