Information About Recording Pulse Oximeter

By Annabelle Holman


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.

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.

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 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.

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.

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.

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.
