A pulse oximeter clips onto your finger and indirectly measures oxygen saturation. Mixed venous oxygen saturation (SvO2) is the percentage of oxygen bound to hemoglobin in blood returning to the right side of the heart. Oxygen is taken in by the lungs when we breathe in. In circulatory conditions like heart disease, inadequate blood flow can prevent optimal oxygen delivery. We have adapted and delivered comprehensive infection prevention, including COVID-19 precautions, safety innovations and processes to safeguard you during your visit. A low saturation level could indicate a respiratory illness or other medical condition. But generally speaking, when oxygen saturation drops below 95%, levels are considered abnormal or below normal. These drops in oxygen levels are called desaturations. Pulse oximeter readings are expressed as a percentage. In short, blood oxygen saturation is the amount of oxygen within a blood cell. For example, someone older than 70 years of age may have an oxygen saturation level of about 95%, which is … Supplemental oxygen could have the most significant direct impact and is prescribed by your primary care doctor or pulmonologist.

Oxygen saturation refers to the level of oxygen carried by red blood cells through the arteries and delivered to internal organs. Some people require supplemental oxygen 24 hours a day, whereas others use supplemental oxygen only as needed. The two terms are sometimes confused, but are distinct in that hypoxemia relates to decreased oxygen concentration in the blood only.
