Top 3 Best Pulse Oximeter Reviews

Why were people buying pulse oximeters earlier this year? 🇺🇸

COVID-19 is a respiratory illness that can cause lung complications including pneumonia and acute respiratory distress, both of which deplete oxygen levels in the body, according to Johns Hopkins Medicine. Some COVID patients either do not notice or do not have other illness symptoms as their oxygen levels drop, according to Dr. Richard Levitan, who wrote in an op-ed in the New York Times that using pulse oximeters and monitoring blood oxygen saturation can help individuals recognize signs of COVID-19 before they notice any other symptoms. Most at-home pulse oximeters range in price between $25 and $200, and can be bought with pre-tax money from your FSA or HSA account. Increased demand for pulse oximeters was likely driven by people who wanted a relatively inexpensive device that gives out a number for assessing their health, rather than trying to gauge symptoms based on how they feel.
One thing Rizzo says to avoid (unless your doctor tells you otherwise) are phone apps that claim to work as pulse oximeters. “The traditional pulse ox works by shooting two wavelengths of light into the tissue. It’s not just white light, which is what most of the phone apps would use,” he says. This means the technology of a phone oximeter app is fundamentally different than an actual device, so if you’re relying on an oximeter for clear, consistent data, it’s best to stay old-school until more testing is done on phone oximeter apps. (Physical pulse oximeters that link to a phone app to track readings are medically fine, though may cost you more for that feature.)
If you do get an oximeter, Rizzo recommends speaking with your physician about it so you have context for what the numbers it displays mean for you. “The more information you have about what to do about the number on the pulse oximeter, the better you’ll be able to handle it,” he says. “It’s one number to be used along with everything else when you either call or do a televisit with your healthcare provider and say, ‘This is how I’m feeling,’ [and also mention the number on your pulse oximeter],’” he says. “It’s just additional information. It’s a matter of access and affordability.”

How to ensure the accuracy of measurement during the СОVID-19 pаndemiс?

We’ve discussed what pulse oximeters measure and how they work. Now we need to talk about the normal ranges for heart rate and oxygen saturation. 

  • Heart rate –  60-100 beats/min
  • Oxygen Saturation –  95-100%

Keep in mind, these are the normal values for an average adult. The ranges differ depending on your age. And while the normal range for oxygen saturation is 95-100%, the level isn’t considered to be dangerously low until it drops below 90%.

In such a case, that is referred to as hypoxemia, which means that there is an abnormally low level of oxygen in the blood. Hypoxemia is treated with supplemental oxygen. 

How to Use a Pulse Oximeter?

When oximeter is turned off,insert finger into to oximeter, Press the operating button

The measurement result will be read directly from the screen within 8s

It recommended that the finger thickness should between 8-25.4mm

Ring finger, middle finger and index finger are recommended as suitable monitor posoition

Choice your accurate reading

Oximeter use the most advanced photoelectric principle, through the high-quality transparent acrylic panel screen to let people directly judge whether the measuring environment is suitable for measurement, to avoid the influence of strong light on the measurement results, so as to ensure high accuracy.


The normal range of oxygen saturation was SpO2 95%-99%.


Insufficient oxygen supply: SpO2 90% – 95%;


Mild hypoxemia: SpO 2 < 90%.


Severe hypoxemia: SpO 2 < 85%.



  • ✅ 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.
