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.
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 factor to check is the accuracy of the device. Normally most devices allow a certain level of error in their readings. The error margin is normally highest in the low-end devices hence one should make the choice carefully. The margin should not exceed two percent. To determine the level of accuracy, one may have the heart rate and blood O2 saturation measured through other means and then the values compared to those of an oximeter.
One must also check the information shown and the kind of display it is displayed on. Normal LED displays are the commonest in low-end products. No other information besides heart beat and oxygen concentration are displayed by cheap devices. High quality commodities have superior displays that display extra information like menus, perfusion index value, battery level indicator, pulse waveform, and pulse meter apart from the 2 main parameters.
The gadget chosen should allow the user to set threshold values for the two parameters. Devices with this capability also incorporate alarm systems for alerting the user when the values of the two parameters go below or above the threshold. This way, preventive measures can be taken to avoid serious conditions if the patient under medical care. Alarms also warn when battery levels fall below a certain percentage.
Like all electronics, oximeters should also have reasonable warranty periods. The normal warranty period is two years. If the warranty is less than two years, it is advisable to seek other options especially if the product costs high. This helps to avoid loses due to the mistakes of the manufacturer.
When buying a product that utilizes rechargeable lithium ion battery, one must check to ensure that it has not been on the shelf for more than one year. This is because damages are caused to lithium ion batteries when the discharge process takes a long period. The best products to settle for are the ones that use both standard alkaline and rechargeable batteries.
