What is the normal o2 saturation?

A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood. If your home SpO2 reading is lower than 95%, call your health care provider.

What is a bad o2 saturation level?

The medical definition of a low blood oxygen rate is any percentage below 90% oxygen saturation. Oxygen saturation below 90% is very concerning and indicates an emergency. Call 911 immediately if you or someone you know experiences such a low blood oxygen level.

What should your oxygen level be?

Your blood oxygen level is measured as a percentage—95 to 100 percent is considered normal. “If oxygen levels are below 88 percent, that is a cause for concern,” said Christian Bime, MD, a critical care medicine specialist with a focus in pulmonology at Banner – University Medical Center Tucson.

What does o2 saturation tell you?

The oximeter display shows the percentage of oxygen in your blood. For someone who’s healthy, the normal blood oxygen saturation level will be around 95–100%. If the oxygen level is below this, it can be an indicator that there is a lung problem.

When to start supplemental O2?

When the oxygen saturation falls below 89 percent , or the arterial oxygen pressure falls below 60 mmHg – whether during rest, activity, sleep or at altitude – then supplemental oxygen is needed.

What oxygen saturation level is dangerous?

Oxygen is a critical nutrient and the body can die within six minutes without it. Any level below 88 per cent is dangerous and incapacitating to your body.

What is normal pulmonary artery saturation?

Many physician offices measure this by putting a pulse oximeter, commonly called a pulse ox, on a patient’s finger. There are two numbers on the pulse ox, the pulse and the oxygen saturation. A normal oxygen saturation reading is 95-100%. Physicians aren’t generally concerned about readings above 90%.

When to worry about oxygen saturation?

Oxygen saturation levels less than 90 percent should be considered a medical emergency, WHO advises. Symptoms of hypoxemia , including cyanosis, or a bluish coloring to the skin and mucus membranes, aren’t evident until oxygen saturation falls below 90 percent.
