Anaesthesia machine itself has evolved from a simple pneumatic device to a complex array of mechanical, electrical and computer – controlled components. Much of the driving force for these changes have been to improve patient safety and user convenience. Though many modifications have been brought out still the basic design has not much changed. Hence, knowledge of the basic design of the anaesthesia machine is a must for all the practicing anaesthesiologists to understand the modern anaesthesia workstation.
