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.
Their working is based on scientific principles that have been in place for long. Ideally, oxygenated blood absorbs the red light at 660nm significantly different from 940nm where the deoxygenated blood absorbs infrared light. With this in mind, the gadgets are designed to emit the two light rays (red light and infrared light from) from LEDs. These are passed through the body tissues and absorbed by the data readings obtain includes the oxygen level in blood, the pulse rate and cardiovascular conditions.
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.
