Understanding Wrist Pulse Oximeters And Why You Need One

By Leticia Jensen


The level of oxygen supply in the blood must be at the right level for normal body functioning. The muscles which are responsible for any movement in the body primarily depends on oxygen if they are to function as expected. When the brain is short of oxygen supply you are likely to feel dizzy or even faint. Death is very common in case of an acute shortage. With this said, the question is how to keenly monitor oxygen level in the blood system. The solution lies in oximeters designed for home use and in particular, the wrist pulse oximeters.

Hospitals depends on specific oximeters (devices used to determine the level of oxygen in blood) designed for this purpose. In fact, this is one of the first tests you are taken through for any medical checkup purpose. With understanding of just how important to keep track of oxygen level in blood, this device has been able to find its place in our houses.

The device is designed with multiple sensors and as such is attached to the wrist with the sensor over the finger. It is very small and light in weight with Bluetooth connectivity and is won like a ring. It therefore transmits data to a computer or cell phone as long as it has software to manage data. This means that you will need to buy software along with the device.

This equipment is the best mate if you need to keep tracking the oxygen percentage in your blood. If you are asthma patient for instance, this is the device you need. It is can also be necessary during time of rest. It comfortably fits over the fingers without having to penetrate the skin. It works by shinning red and infrared light of the skin. In this way, it is able to determine the level of oxygen in the hemoglobin.

When you compare it to the hand held, table top or other similar oximeters, it emerges as the best in terms of advantages. It is very portable, light in weight, longer battery life and is also cheap and easy to operate. The memory storage is also good allowing for reference later on. In addition to this, the device is easy available and is affordable for many people.

Given that this device operates by emitting red and ultraviolet light, other foreign light may hinder its optimal operation. Other than this, movements may also disrupt its accuracy in operation, the reason why it is best used over night. The other area of limitation is as a result of over reliance of pulse rate. While it works best with stronger pulse rate, it does not work properly with weak heat beats.

They are however limited when it comes to alarms. They are primarily used sleep screening and this does not allow for alarms. Although they are still good when it comes to spot checks, the table top, finger held or hand held versions are better with spot checks. They also depend on light and will require that no other strong light is present as this can affect readings. It is also better for more readings to obtain more conclusive results.

It is generally agreed that everyone is his first doctor. The implication is that you must be in constant check of how well your entire body is. In order to be able to do this, you need special devices that give quick feedback various data that matters to your health. One of this is the special oximeter.
