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 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.
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 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.
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.
