A blood draw is a painful process that requires inserting a needle into a vein.
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.

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
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.
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.

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.
