A pulse oximeter has long been touted by physicians as a must have medical device that is needed to monitor the pulse rate and oxygen levels of individuals wherever they are.
The device has actually changed dramatically over the last decade because it has been transformed from something that was not very portable to a medical device that is completely wireless and portable now.
The pulse oximeter works in a very technical way but its application to daily life is very simple.
In essence, what the individual does is that they place their finger inside the device which is only a fraction of the size of a typical cellular phone.
Once their finger is inside the device then they will get a reading of their pulse rate and oxygen levels within seconds.
This reading is actually continuous so if you begin to run or sit down the increase or decrease in blood flow throughout your body will be reflected by the device.
What the physician does is that he recommends buying the pulse oximeter for home monitoring needs.
Once the individual monitors themselves at home they can call the physician with their readings and the doctor will be able to determine if they person is functioning at optimal health or whether there is a need for concern.
The device is very portable and can be taken anywhere that you need to go because it is powered by a set of triple A batteries that you can actually opt to purchase the rechargeable kind if you desire.
Many years ago the medical devices went through a transformation in that they became much smaller through the invention of new technology that allowed them to get mobile and able to be manufactured in the fraction of the size of previous models as they were in the past.
