This measures how much oxygen your blood is carrying. This is called the oxygen saturation and is a percentage scored out of This is important to know because when your oxygen level is low, the cells in your body can have a hard time working properly.
Low blood oxygen, known as hypoxemia, means that the level of oxygen in the blood has dropped below average, normal levels, due to one or more of many different causes. Under most circumstances, breathing room air, normal readings range from 95 to percent. Levels above 90 percent are not considered low, so you probably are worrying unnecessarily.
Your blood oxygen level indicates how much oxygen your red blood cells are carrying. High blood oxygenation plays an essential role in ensuring that your muscles, brain and other organs receive the energy they need to function properly. Oxygen saturation SpO 2 measures how much oxygen blood carries in comparison to its full capacity.
Every body needs oxygen. In fact, every tissue and every cell in the body needs a constant supply of oxygen to work properly. Oxygen gets into our cells and tissues via the lungs.
Hypoxemia occurs when levels of oxygen in the blood are lower than normal. If blood oxygen levels are too low, your body may not work properly. Blood carries oxygen to the cells throughout your body to keep them healthy.
Your blood oxygen level is a measure of how much oxygen your red blood cells are carrying. Your body closely regulates your blood oxygen level. Maintaining the precise balance of oxygen-saturated blood is vital to your health.
Hypoxemia is a below-normal level of oxygen in your blood, specifically in the arteries. Hypoxemia is a sign of a problem related to breathing or circulation, and may result in various symptoms, such as shortness of breath. Hypoxemia is determined by measuring the oxygen level in a blood sample taken from an artery arterial blood gas. It can also be estimated by measuring the oxygen saturation of your blood using a pulse oximeter — a small device that clips to your finger.
Oxygen saturation—sometimes referred to as O sats, or simply, sats—refers to the extent to which hemoglobin is saturated with oxygen. Hemoglobin is an element in the blood that binds with oxygen to carry it through the bloodstream to the organs, tissues, and cells of the body. Normal oxygen saturation is usually between 96 percent and 98 percent.
Share this post:. The body requires a specific amount of oxygen in your blood to function properly. The normal range of oxygen saturation for adults is 94 to 99 percent. Anyone with an oxygen saturation level below 90 percent will likely require supplemental oxygen, which is prescribed by your primary care doctor or pulmonologist.
