Buying Tips For Recording Pulse Oximeter

By Deanne Shepard


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.

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 with alarm systems have added advantage because they are life-saving. The life-saving capability comes in because the gadget can be set by the user to notify them upon the occurrence of certain events. For instance, the user gets notified when their blood oxygen saturation level or heart rate falls or rises beyond a given level. This feature can be very vital for people under critical medical conditions.

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 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.
