What One Should Know About Recording Pulse Oximeter


By Annabelle Holman


Pulse oximetery helps to record two important pieces of information about patients. These two pieces of data are the rate at which the heart beats and the percentage of blood oxygen saturation. This method is considered non-invasive because no kind of penetration is done to the body. Patients who are under CPAP therapy for apnea can use a recording pulse oximeter to determine how effective the efficiency is.

Research has indicated that at night time when apnea activities are happening, blood oxygen level reduces. Such drops in oxygen level can be recorded over time and then used to compare with previous recordings hence helping in determining if therapy is helping or not. Oximeters with recording capabilities have several features that make them worth having. For instance, heart rates and blood oxygen concentration levels are able to be determined 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. 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.

An alarm function is incorporated in all good devices. The user is normally warned by the alarm when threshold values fall or exceed a given level. Threshold values are normally set by the users themselves. Therefore users receive a warning to know that the threshold blood oxygen saturation or heart rate has been surpassed or has dropped. Users are also warned when batteries fall 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.

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.
