Claims made by producers of pulse oximeters make it hard to select the right gadget. This is usually the case especially if one is ignorant about the important features a good gadget should have. The information in this article should be able to help potential buyers in picking the right CMS pulse oximeters. All important features are highlighted although further research can be done to have more knowledge.
First, there are many reasons why it is useful to use a pulse oximetry device. One of the reasons is the immediacy with which one can check their heart rate and blood oxygen concentration. This is important especially during exercise or to pilots because normal brain functioning may be affected by changes in altitude and air pressure in some people. Patients with sleep apnea should also wear the device when going to sleep to determine the efficiency of CPAP therapy.
Checking for recording capability in a device should be the first thing. Devices with recording capability keep a record of values measured over time. Comparisons can therefore be done over a given time frame. An analysis of the recordings should tell when at night apnea activities occur. This is possible because, during apnea activities, oxygen levels in blood drop and heart rates increase.
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.
Oximeters that use rechargeable lithium ion batteries should not have been on the shelves for over a year at the time of purchase. This is because too much discharging in these kinds of batteries damages them. Choosing a product that can use both rechargeable and alkaline batteries is an added advantage.
