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.
The most common devices in currently can only use 2 battery types, the rechargeable lithium-ion and alkaline battery. Alkaline batteries are permanently fixed in the gadget preventing them to be serviced. They also cannot be recharged. They may take years before they need to be replaced. Depleted battery can affect performance and accuracy of a device. Lack of batteries to replace depleted ones also limit the life of certain models.
On the contrary, rechargeable batteries last longer making them cost effective. The only service they need is recharging, when power runs out. Charging is even more convenient because it can be done when the gadget is in use. Some recent oximeter models are however capable of using both alkaline and rechargeable batteries. This provides much flexibility to the user in terms of power sources. Such models are better than those that are specific in the battery type they can use.
There is life-saving capability in products that have alarm systems. Alarms are set by the user to ring upon the occurrence of certain events. For example, when heart rate or blood O2 concentration goes above or below a specific level, the device through the alarm system, notifies the user. The health staff can therefore react fast enough to such occurrences if the patient is under a comma or sedatives.
All values recorded by the gadget are presented to the user through the display interface. The display chosen should be clear and readable with minimum effort. Expensive models normally have superior displays as opposed to LED displays in cheap models. Additional data like battery level, pulse meter and waveform, menus, and perfusion index should also be displayed.
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.
The features and quality of a product dictate its price. Quality should not be overlooked for cost when buying and oximeter. That is because poor quality can cause problems in sensitive cases. It should be known that high accuracy devices cost a lot.
