Abstract
An anesthetic vaporizer is disclosed having an inlet for receiving carrier gas and an outlet for delivering carrier gas with an anesthetic agent to a patient. The vaporizer has a passage that extends between the inlet and the outlet, a vaporizing chamber and a passageway extending from the vaporizing chamber to the outlet. A means such as a differential pressure transducer monitors the differences in pressure between the carrier gas in the passage and the anesthetic agent in the passageway to control the flow of the anesthetic agent through the passageway.
