What is a pulse oximeter?

A pulse oximeter can measure the amount of oxygen in someone’s blood. This is a small device that can be clamped on a finger or another part of the body. They are often used in hospitals and clinics and can be purchased and used at home.

Many people believe that oxygen level is an important indicator of human working conditions, just like human blood pressure or body temperature. People with lung or heart disease can use a pulse oximeter at home to check their condition as instructed by a healthcare provider. People can buy pulse oximeters without a prescription in some pharmacies and stores.

Pulse oximeter can tell if someone has COVID-19, or if someone has COVID-19, what is their condition? We do not recommend that you use a pulse oximeter to determine if someone has COVID-19. If you have signs of COVID-19, or if you are close to someone who has the virus, get tested.

If someone has COVID-19, a pulse oximeter can help them monitor their health and find out if they need medical care. However, although a pulse oximeter can help someone feel that they have a certain degree of control over their health, it does not tell the whole story. The oxygen level measured with a pulse oximeter is not the only way to know someone’s condition. Some people may feel nauseous and have good oxygen levels, and some people may feel good but have poor oxygen levels.

For people with darker skin, the pulse oximetry results may not be as accurate. Sometimes their oxygen levels are reported to be higher than actual levels. Those who check their own oxygen levels or check their own oxygen levels should keep this in mind when reviewing the results.

If someone feels short of breath, breathing faster than usual, or feels uncomfortable to perform daily activities, even if the pulse oximeter shows that their oxygen level is normal, the oxygen level may be very low. If you have these symptoms, call your doctor or other healthcare provider immediately.

The normal oxygen level is usually 95% or higher. Some people with chronic lung disease or sleep apnea have a normal level of about 90%. The “Spo2″ reading on the pulse oximeter shows the percentage of oxygen in someone’s blood.
