The engineering of pulse oximeter did not start a few years ago. These devices have been in place for long now and were first made available for commercial purpose in 1970s. At this time, they were cumbersome and very bulky. To make matters worse, the price tag did not favor the majority of the population. The average retail price was somewhere in the range of $ 10,000. There has been however a drastic change over time and just with a few dollars one can get a very nice recording pulse oximeter.
The working of these devices relies on a very technical scientific principle. Oxygenated blood absorbs red light at 660nm while the deoxygenated blood absorbs infrared light at 940nm. As such, the pulse oximeters are made of two light emitting diodes (660nm and 940nm) and two light collecting sensors. The light emitted from LEDs passes through the tissues and are then collected by the sensors that then measures mount of infrared and red light in it. This allows for recording and reporting on oxygen saturation level. Most of the pulse oximeters are able to deliver data n pulse rate, the level of oxygen saturation and cardiac output.
Even with the same working principles, different models differ in a number of ways. Most significantly though, there are critical differences where your selection criteria should be based on. It is advisable that the rice or brand name should not be the first issues to consider, but rather go deep and find out about their working.
First of all, the brand and manufacturers should be FDA approved. Just like many other medical devices, these gadgets falls in the type II category and requires FDA approval before distribution to the public. It does not hurt to enter the brand name or manufacturer name through the FDA Medical Device Database and confirm.
Other than that, the issue of accuracy and dependability is very important. With the basic role of measuring the oxygen absorption rate and the pulse rate, the point is to get the devices that have the highest possible accuracy level with the most reliable readings. Most people compare the available options to those in hospitals so as to be sure of their dependability.
As much as possible, your device should be easy to use. In fact, the manual guide should be enough to help you through. If you find yourself having to find an expert to help you, then the device is possibly not the right one. In addition to this, the size also matters. Most people prefer a sizable one that is easy to carry around and safely store.
Together with these, there are many other features that additionally contribute to optimal choice. These include the device memory and its ability to connect with the computer or a mobile phone to facilitate data analysis. There are those gadgets that have storage capacity for more than one individual. Such gadgets are considered to be better choice, particularly for the family.
Lastly, you should look at the battery life, the ease of storage, logbook, storage case and general appearance. This together with the software that it runs with matters a lot. If all measures are taken to select the best device, your health and that of family members will be better managed.
