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.
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 first factor to consider is the display the device has. Ordinary devices will normally show only two pieces of information, the heart rate and blood O2 concentration in LED display. However, in more advanced devices, additional information may be displayed in a better display. The additional information may include perfusion index, pulse meter, pulse waveform, battery level indicator, and various menus. The menus open different functions depending on the model of the device.
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.
Oximeters may have one of the two major kinds of batteries. The major battery types in use today are the standard alkaline and rechargeable lithium ion. The lithium ion type can be recharged by electricity when it gets discharged. Because of this, lithium ion batteries are considered cost effective and durable unlike the un-rechargeable alkaline types. Both alkaline and lithium ion batteries can be used in some models of oximeters. This allows users some level of flexibility in their choices.
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.
Extra functionalities can be checked after one ensures that all important functions are present. A device that can wirelessly have all real time values transmitted to the computer on which the software that accompanies the oximeter is installed is better off. Third parties like caregivers can gain from such capabilities.
