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.
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.
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.
Other than this, simplicity also matters. As much as possible, the user guide should be enough to guide you through without having to hire services from an expert which significantly increases expenses. What this means is that the ideal device is very easy to use, read and interpret data. Additionally, its size should also be comfortable to carry around and store as required.
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.
Other issues that should also put into consideration are the battery lifespan, the case for the device, its logbook, the ease of storage and general appearance among others. If all these are put into consideration, then the value for money is likely to be realized.
