Pulse oximetry is important in many situations making it necessary to carry the device everywhere. Recording pulse oximeter is an oximetry device used for measuring the level of saturation of blood oxygen and the rate of heart beat. The word recording is used because the device is able to record and maintain a list of values in memory. Memory is normally in form of a computer, which runs the software that accompanies the device.
With advancing technology sophistication of modern devices is very high making it necessary to have some knowledge about them before setting out to buy one. Novice buyers can find the information in this writing useful. Generally, battery type, size, comfort, display, wireless or Bluetooth capability, accuracy, compatibility with other gadgets, perfusion index, and warranty are some of the factors to consider when buying an oximeter.
Alkaline and rechargeable lithium-ion batteries are the 2 types of batteries in these devices. Alkaline batteries cannot be serviced because they come already fixed in the oximeter. They can last many years, but they must be replaced when they eventually degrade. The affect the accuracy and performance of the device greatly once they start failing. The life of some models is also limited due to lack of replacement batteries.
Rechargeable batteries on the other hand are very durable and cost effective over time. They only need to be recharged when they discharge. Charging can be done even when the instrument is in use making the batteries even more convenient. There are however some models of oximeters, which can use both alkaline and rechargeable batteries. Going for such models can offer an added advantage.
Devices that incorporate alarm systems have life-saving capability. The user can program the gadget to alert them when certain events take place. For example, the device notifies the user through an alarm when blood oxygen saturation or heartbeat rises or falls below a certain level. Such notifications are important to the health staff when a patient is under a life threatening medical condition.
The display is the interface through which the user communicates with the device. Choosing a product with clear and easily readable display is advised. Expensive models come with better displays than those found in cheap brands. Better displays also show information like pulse waveform and meter, menus, perfusion index, and battery level.
Devices with Bluetooth and/or wireless capabilities are able to automatically download all recorded data on a PC. The user can set the download to happen at given intervals. This way, data is backed up for future use at all times. The health staff in a home finds such capabilities useful because they do not need to disturb the patient to take readings.
Cost is dependent on quality and features incorporated in the device. Quality should not be traded for cost when making a purchase because that can be dangerous. Some of the most accurate devices cost very highly.
