Best Pulse Oximeters in 2021 (Top 10) – Buyers Guide

A pulse oximeter is a medical device that measures the oxygen content in the blood,” says Tsuang. “It’s an indicator of how much oxygen from the air we’re breathing into our lungs gets into the blood.” Clipped onto a fingertip, the device displays both oxygen saturation, as a percentage of red blood cells carrying oxygen, and your pulse rate.

The normal range for oxygen saturation is 95–100 percent. Tsuang typically prescribes them for home use in patients with preexisting lung conditions or those who require supplemental oxygen. Because COVID-19 and pneumonia related to the infection can cause low oxygen, oxygen monitoring is critical in more severe cases.

Pulse oximeters have traditionally been used by nurses and clinicians, or for home monitoring with conditions like chronic obstructive pulmonary disease (COPD) or pulmonary fibrosis. The device is a painless, reliable way to check someone’s oxygen saturation—or the amount of oxygen that’s currently being pumped through your blood.

If you feel uncomfortable all the time and feel like something is wrong with your body and vitals, but does not have the option to go to a hospital or clinic near you, then this product is a must-have for you.

Pulse oximeters for use at home aren’t new, but as COVID-19 continues to make health and safety a top priority, more people are looking for ways to manage their health.

The benefit here, of course, is designed for sports and recreational users that wish to measure pulse rate and strength while on the fly.

Precision is key, no matter what the circumstances of operation. The oximeter needs to be accurate, reliable and has an excellent battery life so that you can be sure the oximeter will power up when we need it.

This is where the majority of users have been especially satisfied by the SM-110. It provides SpO2 readings and pulse measurements and the LED display is large yet battery efficient.

Getting Accurate readings from an oximeter

Even if the oximeter is functioning perfectly without any fault, you might at times end up with wrong and inaccurate results if you do not follow the procedure. Therefore, the following points must be followed in the quest for accurate readings.

Wash your hands properly.

When a pulse oximeter works, it shines some light through the skin. Therefore, in case the skin is dirty, the functioning of the gadget can get interfered with resulting in wrong readings. This call for the cleaning of your fingers and skin before applying the clip on your fingers.

Remove the nail polish

The nail polish similarly blocks the oximeter functionalism by absorbing the produced light. As a result, the information that you would receive would be inaccurate.

Avoid subjecting the oximeter to bright light when in use

Since the gadget operates by emitting the light, exposing it again to excess light when in use would interfere with the light from the system leading to inaccuracy.

Stay still when using the oximeter

It is advisable to avoid moving the body parts when taking the readings for a perfect and accurate result. However, even when measuring the level of oxygen while exercising, you need to stay still when taking the readings.

Best Pulse Oximeters For Your Fingertip Buyer’s Guide

The Most Important Features to Consider

  1. Accuracy
    Accuracy is paramount in any medical tool, even ones that aren’t officially intended to act as professional hospital-grade medical tools, but even more so for ones meant for self-diagnosis by non-medical professionals. Therefore it’s a good idea when choosing a portable fingertip oximeter that claims of accuracy on the manufacturer’s part are backed with published evidence or the equivalent. Though peer-reviewed academic studies aren’t likely to be found supporting portable fingertip pulse oximeters, it’s a good idea to see if the products you’re looking at are supported by some sort of clinical trial.
  2. Easy-To-Read Displays
    When testing yourself, it’s important to be able to read the display quickly and easily in any environment and light level- that’s why displays with red or green on black displays are generally the best bet, especially for use during sports and other outdoor or athletic activity. It’s also important to keep in mind that a display that shows more information may actually be harder to read during some activities or by seniors or people with sight issues, so depending on the user, more is not always better.
  3. Compact, Non-Bulky Design
    Oximeters are sophisticated technology and necessarily require a certain amount of bulk to house the needed components and remain durable, but if you’re likely to be using it on the go, it’s ideal to have one that’s been designed to be as compact as possible without sacrificing important features or durability. Thankfully, most commercially available fingertip oximeters at all price lines are designed with this factor in mind, and often include lanyards for wearing around the neck, if they’re too large to fit comfortably in a pocket.
