A perfusionist is a healthcare professional who operates the heart-lung machine during cardiac surgery to manage the patient's physiological status and keep their heart still and unbeating while the cardiac surgeon operates. To become a perfusionist requires a 10+2 medical education with 55% marks minimum, and some institutes require an entrance exam for admission to the B.Sc. degree program. Perfusionists work primarily in operating rooms and ICUs of hospitals and have job prospects managing heart-lung machines and devices like ventricular assist devices. Starting pay for a perfusionist with one year experience is Rs. 10,000-12,000 per month.
