The importance of pulse oximetry has made it a requirement for some people to carry oximeters wherever the go. Recording pulse oximeter is among oximetry devices in use today. It measures heart rate and blood oxygen concentration as the two major aspects. It can also store data recorded over time in memory making it necessary to include the word recording in the name. Normally data is backed up on computers with supporting software.
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.
Batteries normally come in 2 types, that is, alkaline and rechargeable lithium-ion batteries. Alkaline batteries come permanently fitted in the gadget and cannot be serviced. They are capable of lasting several years, but they eventually degrade and need to be replaced. When they start failing, they can cause a major degradation in performance and accuracy of the device. Some models may also not have replacements for the battery shortening their life span.
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.
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 that have Bluetooth and/or wireless capability automatically download recorded data on computers. Users can set the downloads to occur at preferred intervals. This allows for backing up of data to be used later. This capability benefits health workers and patients because patients do not have to be disturbed 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.
