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.
The most common devices in currently can only use 2 battery types, the rechargeable lithium-ion and alkaline battery. Alkaline batteries are permanently fixed in the gadget preventing them to be serviced. They also cannot be recharged. They may take years before they need to be replaced. Depleted battery can affect performance and accuracy of a device. Lack of batteries to replace depleted ones also limit the life of certain models.
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 is able to understand the values measured by the instrument. The display should be readable and clear enough to be seen without much trouble. Cheap models have standard LED displays, but the expensive models have better displays. The display should also be able to show other data such as battery level, perfusion index, pulse meter and waveform, and menus among others.
Devices that have Bluetooth and/or wireless capability automatically download recorded data on computers. Users can set the downloads to occur at preferred intervals. This allows for backing up of data to be used later. This capability benefits health workers and patients because patients do not have to be disturbed to take readings.
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.
