The pulse oximeter technology has been in place for a very long time since it was first made commercially available in 1970s. At the time of introduction, the devices were so cumbersome and could weigh up to 35lbs. They were also uncomfortable to use and were so expensive selling at an average price of 10, 000 each. This has so far changed and getting a nice looking sizable recording pulse oximeter is not an issue any more.
The working of these gadgets depends on scientific principles commonly used. Oxygenated blood usually absorbs red light about 660nm while the deoxygenated blood absorbs infrared light at 940nm. The oximeters are thus designed with two LEDs at 660nm and 960nm and two sensors to gather the same. Once emitted, the LED lights go through tissues from where given amount is absorbed depends on oxygen levels in the blood. The rest is detected by sensors that process it into readable data. Some of the information made available from the device include pulse rate, oxygen absorption rate and the cardiovascular data.
Not all of these devices work in the same manner. It is therefore important to understand features of an ideal oximeter before setting off to buy one. The decisions should be based on the brand name or prices only, rather, focus on getting high quality devices at significantly lower price tag.
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.
