Pulse oximetry is currently of great importance and some people are forced to carry an oximeter everywhere they go. Recording pulse oximeter is one of the models of oximetry devices used to measure blood oxygen saturation and heart beat. The device has the capability to store all values captured over time in a memory hence the name recording. A computer that is running the software that is sold together with the device serves as the memory.
With advancing technology, which raises sophistication in modern devices, one may need to know the exact features to look for in a device before buying. The information in this article is important for novice buyers. Generally, some of the factors to be considered include battery type, display, accuracy, warranty, size, comfort, wireless or Bluetooth capability, compatibility with other gadgets, and perfusion index among others.
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.
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 is able to understand the values measured by the instrument. The display should be readable and clear enough to be seen without much trouble. Cheap models have standard LED displays, but the expensive models have better displays. The display should also be able to show other data such as battery level, perfusion index, pulse meter and waveform, and menus among others.
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.
