What is an Oximeter?

A crooked thought occurred to me long back. The age was to question everything and critically view everyone.

One such thought was how a doctor can hear the pulse through a stethoscope if he is a hearing impaired person. Of course I never asked such weird doubts openly. Those questions were immediately swallowed.

For such doctors, a pulse oximeter will come in handy. Pulse oximeter is a medical device that indirectly measures the amount of oxygen in a patient's blood and changes in blood volume in the skin, producing a photoplethysmograph. It is often attached to a medical monitor so staff can see a patient's oxygenation at all times. Most monitors also display the heart rate.

Look at the picture below.

A person has to slip the instrument on his/her finger and the pulse rate is digitally shown in a few seconds. The device will turn on automatically when a finger is inserted and automatically turns itself off when finger is removed. The pulse oximeter has a bright LED digital display that is easy to read and displays pulse-rate, oxygen level, and a pulse-strength indicator graph.

This instrument runs on battery.
