Pulse oximetry is different; it’s a non-invasive way to gauge the level of oxygen in the blood.

What is a pulse oximeter and how is it being used during the СОVID-19 pаndemiс?

According to the American Lung Association, a pulse oximeter is an electronic device that measures the saturation of oxygen carried in your red blood cells. It can be used by doctors for patients with symptoms of shortness of breath or a known lung or heart condition.

Bravo TV host Andy Cohen, who tested positive for the coronavirus, said the small device helped in his recovery.

According to a report by Yahoo!, Cohen said using a pulse oximeter to monitor his oxygen at home helped keep him from needing to head to the hospital.

“You could scare yourself and think, ‘Oh my God, my lungs don’t feel right,’ but you could use this pulse oximeter and see, ‘OK, well actually, you’re fine, you’re within the range,’” he said.

“So that’s my pro-tip,” Cohen said, according to the Yahoo! article. “Make sure you have Tylenol and a pulse oximeter.”

According to a report by HealthLeaders, officials at Providence Regional Medical Center Everett in Washington State, which admitted the first U.S. COVID-19 patient, are sending patients who are likely positive for COVID-19 but not admitted to the hospital home with a thermometer and pulse oximeter to monitor their symptoms.
When you wear a pulse oximeter, you may see light emitting from the inside of it. This is normal, as one side of the unit generates light of differing wavelengths 🟢 Often, a unit will generate a minimum of two light wavelengths: red visible light and infrared light. Some units generate other light wavelengths, too.

What is pulse oximetry?

When a doctor seeks pulse oximetry information, he or she wants to measure the level of oxygen saturation in the blood. This data helps professionals determine how well the body’s organs are working.

A pulse oximeter is a small device that clips over a fingertip. Some people confuse pulse oximetry with the blood-drawing process, but these are two separate tests. A pulse oximeter doesn’t pierce the skin.

How a pulse oximeter works

The unit generates light

When you wear a pulse oximeter, you may see light emitting from the inside of it. This is normal, as one side of the unit generates light of differing wavelengths.

Often, a unit will generate a minimum of two light wavelengths: red visible light and infrared light. Some units generate other light wavelengths, too.

The light detector receives light

On the other side of unit’s interior is a light detector. It receives and measures the intensity of the light the generator creates.
Light passes through the finger

If your finger were not in the pulse oximeter, the light would easily travel from the generator to the detector. But with your finger in the device, much of the light is blocked and absorbed before it reaches the detector. The detector measures the amount of light that passes through your finger to reach the detector.

The unit interprets light absorption

By measuring the light, the pulse oximeter determines the oxygenation of your blood. Hemoglobin absorbs light waves when it carries oxygen. Additionally, the pulse oximeter uses the light data to measure blood vessel size and non-oxygenated hemoglobin. Within seconds, the pulse oximeter uses this data to determine your oxygenation level.

Tips

  • ✅ If you’re wearing dark nail polish, your pulse oximeter may provide a false reading.
  • ✅ An oxygen saturation level of about 95% is considered normal. Saturation levels below 92% are considered below average.
  • ✅ Pulse oximeters are designed to be portable, so testing can be done wherever you are. Some units are more portable than others, though.
  • ✅ Don’t use a pulse oximeter if your fingers are cold after being outside. Warm up your fingers first for a proper reading.
  • ✅ If your oxygenation levels are poor according to your pulse oximeter, don’t panic. Pay attention to any other symptoms you may be having, and if needed, seek medical attention immediately.
  • ✅ Some pulse oximeters will read your pulse at the same time they read your blood oxygenation level. Track this data for your doctor, too.
  • ✅ Avoid smoking on days you’re taking pulse oximeter readings. The chemicals in cigarettes can cause false readings with some pulse oximeters.

FAQ

❓ What is Oxygen saturation?
Oxygen saturation is a measure of how many hemoglobin proteins in the blood are carrying oxygen molecules.
❓ What level of oxygen is dangerous?
Acceptable range for those without a respiratory disease is between 95 and 99%
An oxygen level below 88% can be dangerous for any period of time. An oxygen level below 85% warrants a trip to the hospital. Keep in mind that an oxygen level 80% and lower puts your vital organs in danger, so it is important to keep a blood oxygen level chart handy so you know what levels require immediate treatment.
❓ Why would I use a pulse oximeter?
Use it as an early warning signal for pneumonia and respiratory disease, one of COVID19 symptoms.
