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.
Each device may slightly vary in its working and it is therefore advisable to consider several features when selecting the best device for the job. If possible, the brand and the prices should not be the main determinants but rather, it is better to look for a device that work best for your situation at the lowest price possible.
The first feature to consider is if the model is FDA certified. Pulse oximeter falls in the category of class II device and hence must be registered with FDA before it can be sold. Currently, most of them are FDA certified by it does not harm to run a check on it by going through the FDA Medical Device Data Base from where the manufacturer name is entered on the search field to access the required information.
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.
The device should also be relatively easy to use. If possible, it should be used by all family members without having to struggle. In fact, the user manual alone should be enough to guide you through without having to involve an expert. It should also be of the size that comfortably work for the targeted end user, be it children or adults.
In addition to these, there are several other features that go a long way in assisting you make the right choice. These include its memory, Ability to connect to a computer or phone to allow for data access and analysis. The devices that have multi-person memory status are also considered deal since data for more than one person.
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.
