Data collected over time through pulse oximetry can be used to check two types of information about a patient. The two pieces of information are blood oxygen saturation percentage and the heart rate. This method is non-invasive and does not involve penetrating the body in any way. For patients receiving CPAP therapy for apnea, a recording pulse oximeter can be used to determine the efficiency of the therapy.
Apnea activities lead to a drop in blood oxygen percentage during the night when they are taking place. Such drops can be recorded by oximeters with recording capability and used to compare with previous recordings made. The efficiency of therapy can be determined basing on the variations found in the recordings. Te extra features incorporated in modern devices make it important to own one of them. For example, spot checks for heart rates and oxygen saturation are possible in modern brands.
Ability to check the 2 aspects on the spot is useful in determining things like effect of height and changes in air pressure on normal brain functions. When exercising or involved in strenuous activities, one may want to know their heart rates and oxygen concentration in blood. These devices have certain features that a buyer should check out for before settling for any specific product.
The display should be the first factor to consider when making a purchase. Ordinary devices based on LED displays display heart rates and saturation of O2 in blood as the only pieces of information. Complex devices however, display more data on a better screen. Most common additional data displayed includes pulse waveform, various menus, pulse meter, perfusion index, and battery level indicator. Depending on the make of product, the menus open various functions.
A good device should also have the alarm function. Alarm function is important in warning the patient when certain threshold values have been reached. Normally the user has the freedom of setting their own threshold. The user can therefore be warned when their heart beat or blood oxygen concentration rises or falls below a given pre-determined level. Another alarm function is for warning the user when the battery level falls below a certain level.
These products come with two main types of batteries to choose from. The first type is the rechargeable lithium ion battery and the second one is the standard alkaline battery. The rechargeable type as suggested in the name can be recharged and reused when they run low. This way, they can last for several years unlike the alkaline types which when they wear out cannot be recharged. Some models of products can use both types of batteries. So it is upon the user to try that possibility out.
Comfort should be placed at the foremost of all considerations. The device should fit comfortably on the area it is attached. Since clip-based gadgets are used even at night, they should remain comfortable after several hours of use. Finger switching can also be done if any form of discomfort is felt.
After checking that all the important factors are well, one may check for extra functions like Bluetooth or wireless capabilities. A device that can wirelessly transmit real time values to the computer running the software is better off. Such capabilities are important to third parties like caregivers.
