How can I measure the oxygen level of my blood during the COVID-19 pandemic?

You can measure your blood oxygen level with a pulse oximeter. That’s a small device that clips onto your fingertip. It shines a light into the tiny blood vessels in your finger and measures the oxygen from the light that’s reflected back.

How does COVID-19 affect the blood?

Some people with COVID-19 develop abnormal blood clots, including in the smallest blood vessels. The clots may also form in multiple places in the body, including in the lungs. This unusual clotting may cause different complications, including organ damage, heart attack and stroke.

What instrument measures oxygen level?

An arterial blood gas (ABG) test is a blood test. It measures your blood’s oxygen level. It also can detect the level of other gases in your blood, as well as the pH (acid/base level). An ABG is very accurate, but it’s invasive. To get an ABG measurement, your doctor will draw blood from an artery rather than a vein.

What device is used to test oxygen levels?

Oxygen saturation is measured by a pulse oximeter, a device placed on the finger that uses light absorption to indicate the level of saturated hemoglobin, the protein on the red blood cell that stores oxygen during transport. Oxygen levels can also be determined through a blood test called an arterial blood gas, or ABG .

What machine measures oxygen levels?

The thing the machine measures, the oxygen saturation, is the proportion (percent) of the hemoglobin in the red blood cells that are carrying oxygen. Our red bloods cells are stuffed full of a protein called hemoglobin, which is a carrier for oxygen.

What device measures oxygen?

The device you are referring to is called a pulse oximeter. It measures the oxygen percentage in your blood flow into the fingertip which is recorded as an oxygen saturation percentage. It helps physicians determine the degree of impairment in oxygen.
