The importance of pulse oximetry has made it a requirement for some people to carry oximeters wherever the go. Recording pulse oximeter is among oximetry devices in use today. It measures heart rate and blood oxygen concentration as the two major aspects. It can also store data recorded over time in memory making it necessary to include the word recording in the name. Normally data is backed up on computers with supporting software.
With advancing technology, which raises sophistication in modern devices, one may need to know the exact features to look for in a device before buying. The information in this article is important for novice buyers. Generally, some of the factors to be considered include battery type, display, accuracy, warranty, size, comfort, wireless or Bluetooth capability, compatibility with other gadgets, and perfusion index among others.
Batteries normally come in 2 types, that is, alkaline and rechargeable lithium-ion batteries. Alkaline batteries come permanently fitted in the gadget and cannot be serviced. They are capable of lasting several years, but they eventually degrade and need to be replaced. When they start failing, they can cause a major degradation in performance and accuracy of the device. Some models may also not have replacements for the battery shortening their life span.
Rechargeable batteries are on the contrary cost effective because they last longer. Power is depleted as they are used and must be recharged. Most devices can still be used as they get charged. Recent technology allow some gadgets to be able to use both kinds of batteries. The user is therefore presented with more flexibility in terms of choice of power source. It is better to settle for such brands of devices than ones that are specific in the kind of battery they can use.
Devices with alarm systems have added advantage because they are life-saving. The life-saving capability comes in because the gadget can be set by the user to notify them upon the occurrence of certain events. For instance, the user gets notified when their blood oxygen saturation level or heart rate falls or rises beyond a given level. This feature can be very vital for people under critical medical conditions.
All values recorded by the gadget are presented to the user through the display interface. The display chosen should be clear and readable with minimum effort. Expensive models normally have superior displays as opposed to LED displays in cheap models. Additional data like battery level, pulse meter and waveform, menus, and perfusion index should also be displayed.
Bluetooth and other wireless capabilities allow the gadget to automatically download recorded values on a computer. The download can be set to happen at predetermined time intervals. This ensures that no data is lost and a record of values is maintained for future use and reference. Such capabilities are useful to health workers in homes because they can keep track of the blood oxygen saturation and heart rate in a patient without disrupting them.
Price depends on quality and features the device has. When choosing, one should avoid trading quality with cost. That can be risky in critical use. Getting a device with a high level of accuracy costs a lot.
