The performance of a respiratory mass spectrometer, modified commercially for use during general anesthesia, was evaluated. Stability and linearity proved satisfactory for monitoring respiratory gases and accurate measurement was possible when the inspired concentration of all gases was < 80%. The system was installed centrally in a 3-room operating theater suite; the selection of lone sampling probes which permit an adequate response time for all gases is discussed.
