All You Need to Know About Finger Pulse Oximeters

by getbetterlife

Finger pulse oximeters have been used in healthcare for a long time. The first device of this type was invented back in 1935. But its use became widespread only in the 1980?s after the development of an infrared measurement system.

The finger pulse oximeter gives a measurement of the oxygen saturation in the blood as well as of the changes in the blood volume in the skin. It also gives an accurate reading of the patient?s pulse. This includes a read out of the pulse rate as well as the strength of that pulse. Some more advanced products can give a read out of the way that the blood volume has changed. There are even apparatuses that measure how well the body is processing the oxygen taken with air. These can also show how effectively the molecules are used by the organism.

Generally all patients with fluctuating oxygenation must have this bodily function monitored during hospital treatments and surgical operations. Finger pulse oximeter is also used during the recovery period so that the doctors can insure that this healing process is effective. Often the patients have to wear such an apparatus even after they leave the hospital.

For this reason the portable finger pulse oximeters are becoming very popular. They are compact and light. They can be used anytime anywhere and a lot of chronically ill people have them on all the time. They are attached to the finger easily without the skin being pierced. They are simply clipped on to the end of the finger. The readings are taken constantly and are displayed on a small screen. This monitor can be separate and attached to the finger clip through a short wire. Alternatively the screen can be on the device attached to the finger. You do not have to be a rocket scientist in order to use such a device. Anyone can operate the gadget no matter how sophisticated its measuring system is.

You can readily purchase a portable finger pulse oximeter at Getbetterlife.com. You will not need a special prescription. However, it is best for you to consult your physician first. In many cases such a device can really save the life of a patient, but it has its limitations. The pulse oximeters cannot show the whole picture even thought they measure the amount of oxygen in the blood accurately. For example, when a patient is suffering from hyperventilation the readings are perfectly normal and they cannot show that there is a poor gas exchange in the lungs. Thus, it is best to ensure that such a device will be useful to you before buying it.
