95 to 100 percent 95 to 100 percent.
1 Venous oxygen saturation (SvO 2) is measured to see how much oxygen the body consumes. 2  Under clinical treatment, a SvO 2 below 60% indicates that the body is in lack of oxygen, and ischemic diseases occur. In medicine, oxygen saturation (SO 2), commonly referred to as sats, measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen. At low partial pressures of oxygen, most hemoglobin is deoxygenated. 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. The 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. Newly oxygenated red blood cells carry oxygen to your body. A pulse oximeter uses light to measure the oxygen saturation level, the percentage of hemoglobin in your red blood cells carrying oxygen. Normal oxygen saturation levels fall between 95 and 99 percent. If you're in good health, normal blood oxygen levels almost always fall within a very predictable range. Medical professionals use two primary measurements for determining your blood oxygen level: oxygen saturation and arterial oxygen. Oxygen saturation is a term referring to the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal blood oxygen levels in humans are considered 95-100 percent. In medicine, oxygen saturation (SO 2), commonly referred to as sats, measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen. At low partial pressures of oxygen, most hemoglobin is deoxygenated. Though the pulse oximeter actually measures the saturation of oxygen in your blood, the results are often used as an estimate of blood oxygen levels. Normal pulse oximeter readings range from 95 to 100 percent, under most circumstances. Values under 90 percent are considered low. 1  Causes. When this level of oxygen falls below a certain amount, hypoxemia occurs and you may experience shortness of breath. Your doctor determines whether you have hypoxemia by measuring your blood oxygen level — the amount of oxygen traveling in your arteries. A range of 94-99% is normal for healthy adults breathing room air which contains 21% oxygen. Anyone who is not achieving the critical blood oxygen saturation level of 90% (SpO 2) or of 55-60mmHg (SaO 2), may require additional oxygen.  The Harvard link I've provided explains that blood oxygen saturation levels are normal at 95%-100%. This is what you would expect a healthy adult to be. What is considered a normal blood oxygen saturation level for a non-smoker how can this be affected by smoking and at what range is blood oxygen saturation considered impaired Resources appreciated.? Normal Blood Oxygen Levels. Healthy people have a normal range of oxygen saturation from 95% – 100%, although levels down to 90% are common and not usually cause for alarm. During exercise, the increased oxygen consumption may reduce blood saturation, but the increased breathing rate and blood flow compensate for this. Oxygen levels remain within the established normal range. Cigarette smoke contains carbon monoxide, which competes with oxygen on the hemoglobin of the red blood cell. Because hemoglobin saturated with CO (carbon monoxide) can not be differentiated from that with oxygen, a pulse oximetry test may indicate the blood level is normal, when in fact the oxygen levels are low. An SaO 2 (arterial oxygen saturation) value below 90% causes hypoxemia (which can also be caused by anemia). Hypoxemia due to low SaO is indicated by cyanosis. Oxygen saturation can be measured in different tissues: 1  Venous oxygen saturation (SvO 2) is measured to see how much oxygen the body consumes. 2  Under clinical treatment, a SvO 2 below 60% indicates that the body is in lack of oxygen, and ischemic diseases occur. In medicine, oxygen saturation (SO 2), commonly referred to as sats, measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen. At low partial pressures of oxygen, most hemoglobin is deoxygenated. Hypoxemia, or low blood oxygen, describes a lower than normal level of oxygen in your blood. In order to function properly, your body needs a certain level of oxygen circulating in the blood to cells and tissues. When this level of oxygen falls below a certain amount, hypoxemia occurs and you may experience shortness of breath. Your doctor determines whether you have hypoxemia by measuring your blood oxygen level — the amount of oxygen traveling in your arteries.
