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.
According to research blood oxygen percentage drops at night when apnea activities are taking place. Oximeters with recording functionalities can record such drops for use in comparing with previous recordings. Variations in the comparisons can be based on to determine the efficiency of therapy. Additional features in oximeters with recording capabilities make it worthwhile to own one of these devices. For instance, one can determine their heart rate and saturation of oxygen in blood on the spot.
Being able to check the 2 parameters on the spot helps in determining how normal brain functions are affected by changes in height and air pressure. People involved in strenuous activities like exercising normally want to know the rates of their heart and blood O2 saturation. Buyers should check for the features discussed below before buying an oximeter.
The display should be the first factor to consider when making a purchase. In ordinary devices with LED displays, heart rate and concentration of blood O2 are the only pieces of information displayed. However, additional information is presented on the screen in a better display in complex devices. Most common additional information includes perfusion index, battery level indicator, pulse waveform, various menus, and pulse meter. Different functions are opened by the menus depending on the brand of the gadget.
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.
One must never ignore comfort in the device. The user should be comfortable with how tightly the device fits on the area of attachment. Clip-based devices that are attached to the finger should be comfortable even after being used for hours especially at night. One can switch the fingers if 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.
