Pulse Oximeters for Sale - How to go for

There are many pulse oximeters for sale on the market. The best one for you depends on your needs and budget. According to our research, if you have very poor blood circulation, you probably need to buy one at the top end; otherwise many high potential cheap oximeters will meet your needs.

The technology of pulse oximeter has come a long way. Today, one can find a finger oximeter for under and it weighs only a few ounces. When it was first ready commercially in the 1970's, it weighed about 35 lbs., and had a bulky and clumsy earpiece. The sensor had weight of 3 lb and looked a C clamp attaching to the patient's ear. It was not pleasant and very uncomfortable.

There are any types of pulse oximeters: from sophisticated models used in operating rooms to simple fingertip models. The fingertip models are widely used at homes, emergency rooms, and hospitals for spot checks. This narrative focuses on the fingertip models from the home-use perspective.

The finger pulse oximeters for sale on the store can be classified into two groups - high-end and others. The high-end one is exemplified by Nonin Onyx 9500, which costs about 0. The most popular vendors for the second group are Beijing choice and Contec curative Systems. We had tested the Nonin Onyx 9500 against two pulse oximeters from Beijing Choice. We tried to portion their accuracy under discrete physiological conditions. We discovered that all the pulse oximeters have similar operation except when the sick person has very low blood circulation. The Nonin Onyx 9500 produced correct readings, while others failed to register any reading. See the link at the end of this narrative for details on the experiment.

In the second group, the prices range from colse to to over 0. The major differences in the middle of these pulse oximeters are building potential and features, such as pleth graph, alarm, Oled display, memory, Pc interface, and sensor size. Of all the oximeters we carry in our store, they are all very well-built; any way we can still see the differences in the middle of the very low-end ones with the best ones.

Pleth graph is an useful feature which is also the least understood feature. I have talked to many customers and only a few noticed this feature. After some simple explanation, they all expressed concerned in keeping an eye on the graph. The pleth graph shows the convert in the volume of arterial blood with each pulse beat. By watching the pleth waveform, the heart beating pattern is clearly displayed. The amplitude of the wave gives an indication of the blood circulation; the waveform can show some irregular heart beats, such as missing beats and bigeminy.

When a heart sick person is having discomfort, it is important to eye the pleth waveform and report the data to his doctor. Since the hurt is ordinarily transient, a physician may not be able to see the waveform during an office visit.
