Maintaining a blood oxygen level of 75–100 mm Hg or 95–100% is vital for a healthy heart, brain, and kidneys. Most people don’t need to monitor their blood oxygen levels regularly.

Blood oxygen levels refer to the amount of oxygen circulating in the blood. Normal blood oxygen levels fall between 75 and 100 millimeters of mercury (mm Hg) on arterial blood gas (ABG) test results.

Blood oxygen levels measure the amount of oxygen in the blood. Normal oxygen saturation levels vary slightly from person to person, but they generally range between 95% to 100%.

A normal blood oxygen level for a healthy adult or child is typically around 95% to 100% SpO2, says Lauren Ferrante, MD, a pulmonologist at Yale Medicine.

One of those vital signs is blood oxygen level, and in the hospital, it’s measured with a pulse oximeter. Patients with Covid-19 can sometimes have relatively mild symptoms and seem to be ...

Low oxygen saturation, often indicated by a low SpO2 reading, means that there is a lower percentage of oxygen in your blood than what is considered normal for your age and health.

Understanding what a normal blood oxygen level reading is for you, is determined by many factors, including your age, whether you are fit and healthy, and any underlying illnesses that you might have.

Normal blood oxygen range for seniors Older adults typically have lower saturation levels compared to their younger counterparts. An acceptable level for some older men and women is around 95 percent.

Apple does not expect the Blood Oxygen function in the Series 6 to be intended for medical use, and so the Apple Watch will not send a notification if a lower than normal blood oxygen level is ...

The Apple Watch 6 and 7 has a blood oxygen app to measure saturation, ... a blood oxygen level of 95-100% is considered normal. Below that, and it might be an indication of an issue.
