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.
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 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.
There is life-saving capability in products that have alarm systems. Alarms are set by the user to ring upon the occurrence of certain events. For example, when heart rate or blood O2 concentration goes above or below a specific level, the device through the alarm system, notifies the user. The health staff can therefore react fast enough to such occurrences if the patient is under a comma or sedatives.
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.
Cost is dependent on quality and features incorporated in the device. Quality should not be traded for cost when making a purchase because that can be dangerous. Some of the most accurate devices cost very highly.
