Pulse oximetry is important in many situations making it necessary to carry the device everywhere. Recording pulse oximeter is an oximetry device used for measuring the level of saturation of blood oxygen and the rate of heart beat. The word recording is used because the device is able to record and maintain a list of values in memory. Memory is normally in form of a computer, which runs the software that accompanies the device.
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.
Alkaline and rechargeable lithium-ion batteries are the 2 types of batteries in these devices. Alkaline batteries cannot be serviced because they come already fixed in the oximeter. They can last many years, but they must be replaced when they eventually degrade. The affect the accuracy and performance of the device greatly once they start failing. The life of some models is also limited due to lack of replacement batteries.
On the contrary, rechargeable batteries last longer making them cost effective. The only service they need is recharging, when power runs out. Charging is even more convenient because it can be done when the gadget is in use. Some recent oximeter models are however capable of using both alkaline and rechargeable batteries. This provides much flexibility to the user in terms of power sources. Such models are better than those that are specific in the battery type they can use.
Devices that incorporate alarm systems have life-saving capability. The user can program the gadget to alert them when certain events take place. For example, the device notifies the user through an alarm when blood oxygen saturation or heartbeat rises or falls below a certain level. Such notifications are important to the health staff when a patient is under a life threatening medical condition.
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.
