What is Iron Lung Machine?

It is one of the oldest life saving machine.

One of the earliest life-saving machines has been the iron-lung machine.It was invented by one Philip drinker of Harvard,U.S.A in 1929.This device is meant to aid who have difficulty in breathing ,either due to paralysis of chest muscles or due to some disease or some an accident .It has an air tight chamber to enclose the patient’s body.

It helps in breathing alternately reducing and increasing the air pressure around the patient’s body.When the pressure is reduced,his chest expands and air streams into his lungs through the normal air passages,as his head remains outside the machine.When the pressure is increased ,the chest contracts and air is automatically expelled from the lungs.

This machine has an tight chamber on wheels.The patient lies on a form rubber bed with an adjustable head and foot rests.It is operated by electricity but has a safety device which gives a warning signal in the case of power failure .The machine can then be operated by hand.

The machine has a cover which can be opened to give access to the patient .The patient’s head is usually enclosed in a plastic dome in which the air pressure is raised alternately raised and lowered to enable the breathing to continue .

During heart operation a heart-lung machine is often used.This takes over the function of  the heart and lungs and the surgeon can perform surgery safely.
