Anesthesia Machine - This term includes the frame, yoke(s), flowmeter(s), vaporizer(s), oxygen flush assembly and all hoses and connections.

Regulator(s) - The regulator(s) are responsible for reducing the supply tank pressure to specified levels.

Oxygen Flush Assembly - The flush assembly is responsible for purging all waste gas from the induction chamber.

Vaporizer - The vaporizer is responsible for changing the liquid agent to a vapor which the patient can inhale. It then delivers the vapor into the moving steam of oxygen in controllable amounts.

Reconditioned Vaporizer - In human medicine, a vaporizer that has been properly cleaned and calibrated for its specific agent and is ready for clinical use. In veterinary use, it could refer to simply a "used" vaporizer or a vaporizer which has been re-labeled for an agent other than the agent for which it was designed. It is recommended that proper questions be asked to determine each sellers' definition of the term.

Service Definitions

Service - A term reserved for any unscheduled work and any repairs directly related to a specific problem. "Service" and "Preventative Maintenance" are occasionally used interchangeably. "Service" is done on an "as needed" basis. "Preventative Maintenance" is regularly scheduled.

Preventative Maintenance Service (P/M) - Annual inspection including checks of all components for proper operation and potential problems. Identification and prevention of possible future breakdowns. Replacement of rubber or other disposable goods.

Calibration - Calibration indicates a vaporizer has been set to standard measuring graduations, under a variety of conditions. Internal components are cleaned of foreign matter and contaminents, new gaskets, seals and wicks are installed. The calibration process takes place while operating under different flowrates, temperatures and time frames.

Efficacy Test - A meter reading of vaporizer output, determining whether or not the output matches the dial reading at both high and low oxygen flows.

Certification - Documentation that all components of the machine have been inspected and perform to manufacturer's specifications. Guarantees that the components are working properly and should continue to perform as expected for another year.
