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.
A pulse oximetry gadget becomes useful in a wide range of circumstances and reasons. The immediacy of checking heart rate and blood oxygen concentration is one of the major reasons. Checking these two parameters is vital especially when one is exercising or when flying because the normal functioning of brain is affected in some people by changes in air pressure and altitude. Efficiency of CPAP therapy in patients with sleep apnea can also be determined by wearing the device at night when going to bed.
The recording function should be the first feature to check for. This function is responsible for maintenance of a list of values recorded over a specific period of time. Variations in measurements can be determined over time. By observing the record, one can tell the time when apnea activities take place during the night. This is because, during apnea activities, heart rates increase and oxygen concentration in blood drops.
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.
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.
A reasonable warranty period should accompany the oximeter purchased. Warranties normally last at least two years for these products. One should seek other options if the warranty does not run for at least two years especially in the high-end models. This protects the buyer from the negligence 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.
