Pulse oximetery is useful for recording two essential pieces of data from patients. The rate of the heart beat and the level of saturation of oxygen in blood are the two pieces of date captured. Since there is no penetration of the body of the patient, the method is referred to as non-invasive. A recording pulse oximeter makes it easier to determine the level of effectiveness of therapy in patients under CPAP therapy for apnea.
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.
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. 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.
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 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.
