Buying Tips For Recording Pulse Oximeter

By Deanne Shepard


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.

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.

Rechargeable batteries are on the contrary cost effective because they last longer. Power is depleted as they are used and must be recharged. Most devices can still be used as they get charged. Recent technology allow some gadgets to be able to use both kinds of batteries. The user is therefore presented with more flexibility in terms of choice of power source. It is better to settle for such brands of devices than ones that are specific in the kind of battery they can use.

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.

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.
