Selecting The Appropriate Recording Pulse Oximeter
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.
The most significant aspect however is to find out is the device is able to give very accurate and reliable readings at its specific working range. The role is to measure the oxygen saturation level in the blood tissue and the results are very useful. As such, your goal is to obtain the device that gives the best possible results. You can compare it with those used in medical facilities for its accuracy level.
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.
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.
