![]() In fact, a 2021 study found that while the accuracy of some at-home oximeters fell short of the ISO standards required for clearance by the FDA, they could still accurately rule out the possibility of hypoxemia.Īccording to a 2016 study, some pulse oximeters that are not approved by the FDA can produce large errors (an average of 6.3 percent lower, or 4.3 percent higher, than the actual result) with blood oxygen saturation measurements. The accuracy of a reading can also depend on the device and whether you’re using it properly.īut these at-home devices can give you a good estimate of your blood oxygen saturation levels. No matter what your finger pulse oximeter says, seek emergency medical attention if you or your child has any signs of low blood oxygen levels, or hypoxemia.įrequently asked questions about finger pulse oximeters How accurate are finger pulse oximeters?Īt-home devices are designed to be easy to use but may not be as accurate as medical-grade devices. Oximeters may also be useful for extreme sports. Such cases may be brought on by acute illnesses, like pneumonia, or flare-ups of chronic conditions, like asthma. Checking that your oxygen saturation level is above the recommended level can help you determine whether you need to seek emergency medical attention. The American Lung Association also says that your oxygen saturation level should be over 90 to 92 percent. If your finger pulse oximeter reading is below 90 percent, try testing again - in case there was a testing error - or consider contacting your doctor. ![]() Readings should typically fall between 95 and 100 percent, with readings at 92 percent or below potentially indicating that there isn’t enough oxygen in your blood. This type of reading is called oxygen saturation, or SpO2, and the results display as a percentage. The light shines through the tissues of your fingertip, and the sensor on the other side picks up the light that comes through.įinger pulse oximeters can then measure how much light comes through your finger to estimate how many of your red blood cells are carrying oxygen. These devices have light-emitting diodes, or LEDs, on the inside of the probe that can send small beams of light through your finger to track the amount of oxygen in your blood. Pulse oximeters are most commonly worn on your finger and are completely painless to use. So, to help make your search a little easier, we’ve compiled our top picks of the eight best finger pulse oximeters so you can start tracking your levels quickly and easily from home. If you’re thinking about purchasing an at-home finger pulse oximeter, it’s important to discuss with your doctor when you should use it, how to interpret the results, and when to seek medical care.įinding the right device for your needs may take some time, and you may be wondering what the difference is between all of these different devices. For example, conditions like hypoxemia can result in low blood oxygen levels, and having a finger pulse oximeter at home could provide better peace of mind. While the COVID-19 pandemic has led to a renewed interest in pulse oximeters for home use, there are many other reasons why you might consider investing in your own device to have on hand. There are several different brands and designs available so that you can easily check your blood oxygen saturation levels from the comfort of your home. Here’s our process.įinger pulse oximeters are usually found at doctors’ offices and hospitals, but what you may not know is that you can also buy one to use at home.
