Pulse Oximeter Price The use of medical devices such as pulse oximeters has increased dramatically in recent years. Basically, pulse oximetry is a painless, noninvasive method of measuring the saturation of oxygen in a persons blood. Overview: Oxygen saturation standard values 5. Any health condition that limits your body's ability to produce red blood cells can result in low hemoglobin levels, which in turn limits the amount of oxygen that can saturate your blood. Oxygen "hitches a ride" on the hemoglobin as it circulates until it gets dropped off to the body's tissues. If your breathing is unassisted, its difficult for your oxygen levels to be too high. A pulse ox cant tell the difference between this other type of gas and oxygen. An.

Warning signs of a low oxygen level include trouble breathing, confusion, difficulty waking up, and bluish For adults less than 70 years of age, the normal oxygen saturation level should range between 96% to 98%. Due to the fact that oxygenated and deoxygenated hemoglobin has a different color and exhibits different light absorbing ability, the oximeter is able to distinguish between them and based on this estimate the blood oxygen saturation value. 2023 Dotdash Media, Inc.
