A portable medical gas system tester is small, lightweight, sturdy, self-contained and portable and can be either pen-activated and/or voice-activated so that it can be operated in the field by just one person. The device can test, collect and interpret data from all medical gas components, such as outlets, valves, alarms, central sources of supply and emergency low pressure oxygen fill connections, and with all medical gases including oxygen, air, vacuum, waste anesthetic gas disposal, nitrous oxide, nitrogen, carbon dioxide and carbon dioxide/oxygen mixtures. The device has a computer, a digital display device, an analog to digital converter, a gas sensor, a pressure and vacuum transducer coupled to the gas sensor, and an oxygen transducer coupled to the gas sensor, an exhaust outlet for venting excess gases to outside of the device's case, a bi-directional flow sensor coupled to gas sensor, and a flow transducer coupled to the flow sensor. The computer analyzes and interprets the electrical signals relative to predetermined values and generates a digital display for an operator to view.

[ What is claimed is:] [38.]38. A method for testing compliance of a medical gas system with a preset standard, comprising:providing an apparatus having a computing device, a display device and a sensor for sensing data from said medical gas system, said display device and said sensor being coupled to said computing device, said sensor including a housing, at least one connector on said housing for mating said sensor with an outlet or inlet of said medical gas system, and a pressure or vacuum transducer and a flow sensing device within said housing, and a variable orifice within said housing between said connector and said flow sensing device for controlling the flow of gas between said connector and said flow sensing device;closing said variable orifice such that no gas can flow between said connector and said flow sensing device;mating said connector with an outlet or inlet of said medical gas system;sensing static gas pressure data from said medical gas system by said sensor;producing an electrical signal related to a gas pressure or vacuum sensed by said sensor, and transmitting said electrical gas pressure or vacuum signal to said computing device;manually opening said variable orifice;continuing to sense gas pressure data from said medical gas system by said sensor;when said measured gas pressure falls 5 psig, producing an electrical signal related to a gas flow rate sensed by said sensor, and transmitting said electrical gas flow rate signal to said computing device;interpreting of said electrical signals by said computing device; andcomparing said gas flow rate data with a preset gas flow rate standard and generating a display on said display device related to the flow rate measurement for said gas as a function of the compliance of said medical gas system with a preset standard.
