6 Best Pulse Oximeters

Pulse oximeters are a valuable tool to use for at-home fitness testing or oxygen-level monitoring, helping people participating in high altitude activities stay safe. Oximeters are also essential for many people around the globe who suffer from cardiopulmonary conditions of all kinds including but not limited to COPD, emphysema, asthma, and heart conditions of all kinds.

If you’re required to go for blood gas testing on a regular basis, your specialist has likely sent you on the search for an appropriate at-home device to measure your blood SpO2 levels on your own, in between lab visits. While at-home devices can’t have nearly the range and accuracy of a million-dollar blood gas analyzer, they are accurate enough to give a pretty good picture of how well your body is taking in oxygen at any given time.

Experts all agree that regardless of what you use them for, pulse oximeters are a sensible alternative to expensive blood gas testing. This is especially true for those who’re at risk for hypoxemia such adventure athletes, pilots, and people with health problems that prevent their bodies from taking in enough oxygen to maintain proper health.

Athletes will appreciate the benefits of knowing whether their exercise efforts are being rewarded with increased oxygen uptake. Pilots can prevent altitude sickness from setting in and endangering their crew or cargo by consulting their oximeter a few times during each flight.

Then there’s the ability for those with cardiopulmonary issues to monitor their health and get help before oxygen saturation levels get too low. Of course, there’s no substitute for a thorough clinical assessment, but oximeters can alert you before there’s a serious problem, prompting you to relax and seek immediate medical care.

Thanks for stopping by and spending some time with us. We hope you’ve enjoyed this read, and now have more confidence in your ability to choose a reliable pulse oximeter for monitoring your own SpO2 levels.
