Abstract

A system for controlling the delivery of medical gases includes a digital signal processor that receives at least one ventilation parameter value change, calculates a fresh oxygen flow rate, total fresh gas flow rate into the breathing circuit, and a reference oxygen flow rate representative of a predetermined oxygen concentration delivered to a patient. A graphical display presents the calculated fresh oxygen flow rate, total fresh gas flow rate, and reference oxygen flow rate. A method of controlling the delivery of medical gases to a patient includes calculating a total fresh gas flow rate into the breathing circuit, calculating a fresh oxygen flow rate into the breathing circuit, calculating a reference oxygen flow rate representative of a predetermined oxygen concentration delivered to the patient and presenting the total fresh gas flow rate, the fresh oxygen flow rate, and reference oxygen flow rate on a graphical display.
