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.
Instant checking of the two parameters assists one to determine the effects of changes in air pressure and altitude on brain functions. The parameters are also normally a concern to individuals taking part in strenuous activities such as exercise. Before buying an oximeter, the buyer should check the presence of following features.
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.
All good devices include the alarm function. Alarms are vital because they warn users when threshold values are exceeded or have fallen below. Normally the threshold values can be determined by the user themselves. Users therefore get warned when blood oxygen saturation or heart rate falls or exceeds a certain level. The alarm also warns users when the battery is empty or below a certain percentage.
Users can choose from two major types of batteries. Standard alkaline and rechargeable lithium ion batteries are the two major types of batteries in use today. The rechargeable type is rechargeable upon being discharged hence can be reused. This makes them durable and cost effective unlike the alkaline types which become useless once they get discharged. Some oximeters can use both lithium ion and alkaline batteries. This gives users a wider range of flexibility to operate in.
Comfort is a factor that must never be overlooked. A good gadget is one that allows some level of comfort to the user. Although most clip-based designs are placed on the finger, one should ensure that they are comfortable even after hours of using the gadget. If there is any form of discomfort, the fingers can always be switched.
Additional functionalities may be checked after ensuring that the important ones are present. Normally oximeters have accompanying software that is installed on a PC. Devices with wireless capability transmit recorded data to the PC in real time. Caregivers and other third parties can benefit from such capabilities.
