The heart is a special organ in the human system. It is pulsating ceaselessly unlike the other organs. Heart surgery is a highly complex operation, as the surgery has to be performed without arresting the heartbeat. At the same rime the functioning of the lungs has also to be kept up.
Medical men of genius invented the heart-lung machine in 1956 to carry on the activities of the heart as well as the lung during cardiac operations. The machine rakes upon itself the function of the heart and the lung ensuring purification of the blood and keeping up circulation of the blood.
The details of the functioning of this heart-lung machine are well known to the doctors. The tube which is fitted connecting the heart and the machine should be airtight and should be fixed with great care, for any lapse in the fitting of the tube may cause air bubbles which will endanger the patient’s life. Unfailing power supply is most crucial for the success of the operation as any interruption in power supply will stall the operation. Therefore we have to depend on generators for ensuring uninterrupted power supply during the course of the operation. (SSS Vol.27, p. 25)
