Low blood oxygen, known as hypoxemia, means that the level of oxygen in the blood has fallen below normal levels, due to one or more of many different causes. Under most circumstances, breathing room air, normal readings range from 95 to 100 percent.
Oxygen levels can also be determined through a blood test called an arterial blood gas, or ABG. This test measures the partial pressure of many blood gasses, including oxygen. Healthy people have a normal range of oxygen saturation from 95% â 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.
