Factors To Consider When Purchasing A Pulse Oximeter

A pulse oximeter is a simple device that measures SpO_2, or blood oxygen saturation level, and pulse rate (BMP). Typically you attach a sensor to your fingertip or earlobe, or to a child’s foot to get a reading. For a healthy individual, blood oxygenation levels should be in the 95 to 99 percent range.

 When purchasing a pulse ox, consider the features that will meet your needs. Units can cost anywhere from $30 to several thousand for the professional models used in hospitals. A simple device that provides accurate readings and is medically approved should be adequate for most home users.

If you want to pay a little more, you may get added features such as a color display and the ability to store and report long ranges of data. This feature can be very useful if you have a chronic condition you need to monitor and report back to your physician. If you have children, you may consider a pediatric oximeter or a hand held unit with a pediatric probe.

Testing the unit you choose against actual blood tests will guarantee not only the accuracy of the unit, but also that you understand how to use it correctly. Most reputable companies offer a refund on their products, so you can choose another unit if you find a discrepancy after comparison.

Other factors to consider include alarms and overall durability. Some patients need a pulseox with an audible alarm so they are alerted immediately to low oxygenation levels. As for durability, some units are designed to resist humidity or be shock resistant in case you drop them. It pays to do a little research to find out what features are available and which ones will be most useful to you.
