An electronic anesthesia delivery apparatus for mixing a carrier gas and first and second anesthetic agents comprises a chassis having an electronic vaporizer, the vaporizer having a first anesthetic chamber and a second anesthetic chamber retaining the first anesthetic agent and the second anesthetic agent, a carrier gas input port in flow communication with the first anesthetic chamber and the second anesthetic chamber, a precision orifice and an electronic control valve corresponding to each of the chambers being downstream of the gas input port, each of the chambers having a conduit in flow communication with the carrier gas input port, each of the conduits extending into each of the chambers below an upper level of anesthetic agent, wherein the carrier gas passes through a porous diffuser near an end of the conduit and bubbles through the anesthetic agent, the chamber further comprising an anesthetic gas outlet port, an electronic touchscreen display for controlling carrier gas flow rate to the first anesthetic chamber and the second anesthetic chamber, the electronic touchscreen display further allowing control of concentrations of the anesthetic agent in an anesthesia to a patient by intermittently opening and closing of the electronic control valve, a circuit board having an input/output portion, the circuit board in electronic communication with the electronic touchscreen display, the input/output portion receiving temperature of the anesthetic agent, the electronic anesthesia delivery apparatus allowing use of a first anesthetic agent while a second anesthetic agent is one of either replaced or substituted in the second chamber.
