Manufacturers of pulse oximeters are currently many and each claims that their products are the best in the market. These claims make it very hard to select the right product for personal use. This becomes even harder if one has no idea about the features the device should have. This article contains useful information concerning the features to ensure are available in CMS pulse oximeters before buying.
Many reasons are available for having ad using a pulse oximetry gadget. The immediacy by which blood oxygen levels and heart rates can be checked is one among the many reasons. It is vital to check these two values especially during workout sessions or when flying. The gadgets are important in flying because variations in altitude and air pressure may cause abnormal brain activities in some individuals. Estimation of the level of efficiency of CPAP therapy is possible through the use of these devices. Sleep apnea patients are advised to wear then when retiring to bed.
The first feature to check for should be the recording function. This function allows the device to maintain a record of values for the heart rate and oxygen saturation for a given period of time. This is useful when doing comparisons to determine changes in the two parameters. Such records can reveal the time of the night when apnea activities are happening. This is because the heart rate increases while oxygen saturation in blood drops when the activities are taking place.
Another aspect of great importance is the accuracy of values measured and displayed. Most devices allow a given degree of error in their readings. Highest error margins appear more in cheap devices hence one should know. Regardless of the type of product, error margins should not exceed 2 percent. Other means can be used to confirm accuracy of a device.
One should also check for the kind of display the device uses and the details displayed. Low-end devices normally use the ordinary LED display and only display the two parameters the gadget is meant for without additional information. Better devices use better displays and also display pulse waveform, battery level indicator, menus, pulse meter, and perfusion index value in addition to the two parameters.
Setting of threshold heart rate and O2 saturation percentage values should be possible in the device chosen. All devices that allow setting of threshold values also have alarm systems. The alarms alert the user when the values rise or fall below the threshold. This way, serious conditions can be avoided by taking preventive measures. Low battery levels are also revealed by the alarms.
The oximeter bought must have a warranty period. Warranties for these products are normally two years or more. When buying a high-end oximeter, avoid settling for those that the warranty does not exceed two years. Warranties provide protection against losses caused by the negligence of producers.
One should avoid purchasing products that use rechargeable lithium ion batteries yet have stayed on the shelves for more than a year at the instance of purchase. This is because lithium ion batteries get damaged when they discharge over a very long period. A better way would be to choose products in which both rechargeable and standard alkaline batteries can be used.
