Feb 18, 2022 · What is a blood oxygen level test? There are two main ways to measure or test blood oxygen levels: through a blood draw test and through pulse oximetry (using an oximeter). A blood draw test provides much more information about your oxygen levels than an oximeter does.
Jun 13, 2024 · A normal range for your blood oxygen level is between 92% and 100%. SpO2 readings can fluctuate based on activity, overall health, and other factors. Your body relies on a coordinated effort between your heart, lungs, and circulatory system to maintain a healthy blood oxygen level.
Sep 13, 2024 · Pulse oximetry is a quick, noninvasive test that measures the oxygen saturation levels in the blood, using a device called a pulse oximeter. It helps monitor how well oxygen is being delivered throughout the body. It is commonly used in hospitals, healthcare provider offices, and at home.
- Oxygen content (O2CT). This measures the amount of oxygen in the blood.
- Oxygen saturation (O2Sat). This measures the amount of hemoglobin in your blood. Hemoglobin is a protein in your red blood cells that carries oxygen from your lungs to the rest of your body.
- Partial pressure of oxygen (PaO2). This measures the pressure of oxygen dissolved in the blood. It helps show how well oxygen moves from your lungs to your bloodstream.
- Partial pressure of carbon dioxide (PaCO2). This measures the amount of carbon dioxide in the blood.
