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 sophistication of modern devices is very high making it necessary to have some knowledge about them before setting out to buy one. Novice buyers can find the information in this writing useful. Generally, battery type, size, comfort, display, wireless or Bluetooth capability, accuracy, compatibility with other gadgets, perfusion index, and warranty are some of the factors to consider when buying an oximeter.
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 on the other hand are very durable and cost effective over time. They only need to be recharged when they discharge. Charging can be done even when the instrument is in use making the batteries even more convenient. There are however some models of oximeters, which can use both alkaline and rechargeable batteries. Going for such models can offer an added advantage.
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.
The display is the interface through which the user communicates with the device. Choosing a product with clear and easily readable display is advised. Expensive models come with better displays than those found in cheap brands. Better displays also show information like pulse waveform and meter, menus, perfusion index, and battery level.
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.
