Pulse oximetry is currently of great importance and some people are forced to carry an oximeter everywhere they go. Recording pulse oximeter is one of the models of oximetry devices used to measure blood oxygen saturation and heart beat. The device has the capability to store all values captured over time in a memory hence the name recording. A computer that is running the software that is sold together with the device serves as the memory.
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.
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 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.
Devices with Bluetooth and/or wireless capabilities are able to automatically download all recorded data on a PC. The user can set the download to happen at given intervals. This way, data is backed up for future use at all times. The health staff in a home finds such capabilities useful because they do not need to disturb the patient 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.
