The new Tec6 desflurane vaporizer.

The Tec 6 vaporizer is an electrically heated, thermostatically controlled, constant temperature, pressurized, electromechanically coupled dual circuit, gas/vapor blender. The pressure in the vapor circuit is electronically regulated to equal the pressure in the fresh gas circuit. At a constant fresh gas flowrate, the operator regulates vapor flow with a conventional concentration control dial. When the fresh gas flowrate increases, the working pressure increases proportionally. At a specific dial setting at different fresh gas flowrates, vaporizer output is constant because the amount of flow through each circuit is proportional. Independent confirmation of vaporizer performance and design characteristics awaits vaporizer availability.
