Abstract
The basic design of the anesthesia machine has changed very little in the past 10 years.1,2,3 The means of providing gas flows to the breathing circuit remains essentially unchanged. Because of the variable effect which fresh gas flows rates have on the breathing circuit gas concentrations, training and experience are necessary before one can deliver a smooth and controlled anesthesia, with existing equipment, particularly when using closed circuit anesthesia. The anesthesia machine can be made easier to use by adding computer control. The anesthetist may then adjust the inspired oxygen concentration, the end-tidal anesthetic concentration, the circuit volume, and the end-tidal carbon dioxide concentration; the computer will set the fresh gas flows. By letting the user set these primary parameters, the machine becomes function oriented and anesthesia safety may improve.
