Description

Within anesthesia machines, delivery of the anesthetic to the patient’s airway is the job of the “breathing system” which incorporates a mask or a tracheal tube. Dr. Ralph Waters (1883–1979) introduced this simple device in 1923 designed to prevent the exhalation of anesthetic into the ambient air or to prevent the patient from rebreathing their own carbon dioxide. Waters placed a carbon dioxide absorber, soda lime, in the canister between the gas inlet and the air reservoir bag. The patient was able to rebreathe anesthetic, “to-and-fro,” while the CO2 was filtered out.
