There are currently many manufacturers of pulse oximeters worldwide today with each claiming to manufacture the best. The many products on the market have made it continuously difficult for buyers to choose the right product. This is so especially if one does not know what to look for in the device. This article provides useful information about the features of CMS pulse oximeters one should look for when 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.
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.
The accuracy of values displayed by the device is also of great importance. Normally a certain error level is allowed in most readings. Low-end devices have the highest error margins hence caution should be exercised when buying them. Whatever the case an error margin of two percent should not be exceeded. Accuracy can be determined by comparing values from the gadget and those measured through other means.
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.
