Things To Be Careful About When Using A Pulse Oximeter

A pulse oximeter is fairly easy to use that even someone without any medical supervision or training can make use of it

. New portable models are made with a button that users can easily press to start the machine. It's easy, quick, and accurate.

However, the accuracy of a pulse oximeter is dependent on several aspects. Without considering these factors, the use of the oximeter will be void. All its benefits will be useless if not used with proper care and attention.

First of all, consider your medical history. If you have prior illnesses or injuries, this may affect the reading of the oximeter. People with asthma, sleep apnea, or other chronic conditions are not advisable to solely depend on the reading of an oximeter. More tests have to be done to have a safer reading. One of the advantages of this device is to help determine the condition of the heart and the lungs. So, if the person already has a chronic lung disease to begin with, he shouldn't be surprised if the oxygen saturation percentage is lower than 95%. Also, the amount of oxygen saturated varies with age which means that an older person might have a different reading than a younger one.

Another thing to consider is that when the oximeter is doing a reading, you should be perfectly still. If you tend to be fidgety with your hands, you might want to place the sensors in your ear. Don't let the probe fall out of your or fingernail when you clip it.

How a pulse> works is made possible of infrared lights and red colored lights. These two lights are absorbed by the blood. The infrared is for the oxygenated blood while the red ones are for the deoxygenated blood. The ratio of these lights is also the ratio of the oxygen in the blood. Since light plays a huge part in determining the oxygen saturation, an external light source can disrupt the results. A bright lit room or sunlight can alter the light emitted by the machine.

Maintain the reliability and accessibility of the pulse oximeter by remembering the different factors that can affect the outcome of blood-oxygen levels. An inaccurate reading will cause confusion and serious medical dilemmas if not handled well.
