Equate’s $39 pulse oximeter gets props from reviewers for its easy readability and accuracy. The oximeter features a backlit display, so you can read your results in any kind of lighting conditions. A stationary pulse oximeter - these are quite bulky and predominantly used in hospitals. The advantage of stationary pulse oximeters is that they provide highly accurate results, allow monitoring several indices and show the data in the form of graphs, which is very convenient. Portable pulse oximeters - these models are best suited for home.

Medical grade pulse oximeter

“A pulse oximeter is a medical device that measures the oxygen content in the blood”

“It’s an indicator of how much oxygen from the air we’re breathing into our lungs gets into the blood.”

Already essential for those with asthma or other lung diseases, a pulse oximeter is an affordable investment that could give you peace of mind during the pandemic.

It’s not only easy to use, but it gives valuable insight into your health that could be helpful to medical professionals.

The normal range of oxygen saturation is 95 to 100 percent. They are generally prescribed for home use in patients with pre-existing lung conditions or those who require supplemental oxygen.

Because infection-related pneumonia can cause low oxygen levels, it’s not surprising that finding a pulse oximeter available online or at your local pharmacy is almost impossible.

Benefits of pulse oximeter

  • Portability – Finger pulse oximeters only weigh a couple of ounces. They are so small they can fit in your shirt pocket.
  • Compact Pulse Oximetry – Finger pulse oximeters display SpO2 (Oxygen Saturation %) and heart rate in beats per minute.
  • Pediatric to Adult – Finger pulse oximeters can work on pediatric to adult patients. finger oximeters have the best patient range. If the user’s finger is thicker than a pencil then the finger oximeter will be able to get a reading.
  • Durable with Warranty: All finger pulse oximeters have at least a two-year warranty and have service centers in the United States.
  • Fast Readings – Finger pulse oximeters provide accurate readings within seconds making it the perfect device for spot checks.
  • Wireless Bluetooth – Fingertip oximeters with Bluetooth can connect to an iPhone/IOS or Android device and send readings for review.
  • Medical Grade: pulse oximeters are used in hospitals and clinical settings throughout the world. They use the same hospital-grade technology in their line of finger oximeters.

Pulse oximetry readings can be affected by

Pulse oximeter alarm limits

Fda

No Alarms: Since finger pulse oximeters are primarily used for spot checks (quick readings) and not for extended continuous readings there are no alarm options for finger pulse oximeters. We recommend handheld or tabletop oximeters with alarms if the alarm option is required.

Pulse oximeter memory

Memory – Most finger pulse oximeters do not have memory, but they have the ability to “stream” readings to an app via a Bluetooth connection to a smartphone or tablet.

Pulse oximeter for babies

Infants / Neonates: Finger oximeters will not work on infants and neonates. Handheld and tabletop oximeters with a properly sized sensor are still the best way to take oxygen and heart rate readings from infants and neonates.

The pulse oximeter can work on pediatric toes or fingers as long as the size is the thickness of a number 2 pencil or larger. No other finger oximeter can work on digits that small.

What is the most accurate pulse oximeter?

Many low-cost pulse oximeters sold to consumers demonstrate highly inaccurate readings. But, the accuracy of some low-cost pulse oximeters tested performed similarly to more expensive, ISO-cleared units when measuring hypoxia in healthy subjects.

Pulse oximetry is a quick and easy way to determine how well oxygen is being sent from the heart and lungs out to the furthest parts of the body, which can help determine if your heart and lungs are functioning properly.

Pulse oximeters can be used to gauge warning signs for chronic lung or heart conditions, and may help determine whether you should seek medical attention for the coronavirus.

Here's what you need to know about what exactly a pulse oximeter measures, how it works, and how you can use it properly.

What does a pulse oximeter measure?

A pulse oximeter measures the oxygen saturation of your blood. Essentially, this percentage is a calculation of how much oxygen is in the blood, with 100% being 'fully saturated' and the optimal level.

And while this simple non-invasive medical tool is available over the counter in many pharmacies, it's not necessary for most people.

'Unless you have a chronic heart or lung condition that affects your oxygen saturation on a regular basis, most individuals don't need one in their home,' says Albert Rizzo, MD, Chief Medical Officer for the American Lung Association.

Those with lung or heart conditions — such as chronic obstructive pulmonary disease (COPD) or heart failure — may be prescribed home oxygen therapy by their doctor, says Rizzo, and a pulse oximeter can help them to monitor whether the use of oxygen at home is improving their condition or not.

Pulse oximeters have also been used to indicate severe cases of COVID-19. That's because the coronavirus can cause a decrease in blood oxygen levels — though if this occurs, it's likely that you'll recognize other symptoms before needing to use a pulse oximeter.

In fact, Rizzo says that oxygen saturation by itself is often not the best indicator of medical conditions, and other symptoms are just as important to tell your doctor.

Other warning signs of low blood oxygen levels may include:

  • Increased heart rate
  • increased breathing rate
  • Feeling shortness of breath or gasping for air
  • Inability to do an activity that you did before without getting out of breath

For everyday health, you shouldn't rely on pulse oximeter readings alone, says William Berry, Research Scientist at Harvard T.H. Chan School of Public Health. The oximeter numbers are only estimates of your blood oxygen levels — and they should be taken in context.

How does a pulse oximeter work?

To get the most accurate reading on a pulse oximeter, there are a few simple steps, according to the World Health Organization:

  • Position the probe correctly. Depending on the device, this will usually be on the finger, toe, or earlobe. Make sure it is well-fitted, and not being forced on: for example, try the second toe rather than the big toe. If the probe is too loose or too tight, it may allow extra light in, which will impact the reading.
  • Make sure you're sitting still. Shaking or shivering will affect the reading, and may make it seem much lower than it actually is.
  • Remove any nail polish. If you're wearing colored nail polish, this might affect the reading. Finger tattoos or henna dye can also affect the reading: in this case, choose a different finger, toe, or earlobe. Cold fingers or toes can also cause false readings.

There are many types of pulse oximeters, which come with varying features and are sold at a range of prices, so you'll want to find the best pulse oximeter for your purposes.

A 2016 comparison between the accuracy of the pocket or standard pulse oximeter found that the standard oximeter had a precision error of 1.8%, while the pocket version showed 2.21% error. One 2018 study of pulse oximeters used in heart patients suggested that earlobe probes had greater accuracy.

If you think your pulse oximeter might not be accurate, Rizzo suggests checking the pulse reading or heart rate on the pulse oximeter against your own reading of your pulse.

How to read a pulse oximeter

According to WHO, a reading of 95% to 100% on the pulse oximeter is considered healthy and isn't a cause for concern.

If you have no underlying medical conditions, your levels should generally be at 95 or higher. But for people with chronic conditions, it's important to talk with your doctor about what the appropriate reading should be for you, and when you should seek medical attention.

For reference, lower levels of blood oxygen saturation may indicate:

  • Blocked airways
  • Difficulty breathing
  • Lung infection
  • Poor blood circulation
  • Drug interference from anesthesia, muscle relaxants, or anaphylaxis

In addition, if your pulse oximeter reading drops during exercise, Rizzo says it can be a sign of an underlying lung or heart condition and you should speak with your doctor.
