The data had to be derived by classic methods, and had to be consistent and reliable with all subjects during any test regimen. In 1991 we produced the first Max-1 . In actual lab use, we tested and improved it for two years before we sold our first production unit. Brief Specifications - Integrated System Volume Measurement Pneumotach and mass flow transducer, measured in inspiratory air at ambient temperature and humidity. Computer software corrects any non-linearity in the transducer and pneumotach and applies standard correction factors to convert ventilation to B.T.P.S. or S.T.P.D. values.
Adaptations are available for lower ventilation rates.
Oxygen Analysis Rapid paramagnetic analyzer, no periodic maintenance or cell replacement. Carbon Dioxide Analysis Rapid infrared analyzer-permanent, no periodic maintenance or cell replacement. Design Includes simple to use hardware and software, and front panel digital displays of analyzer response has automatic calibration or manual calibration using front panel controls.
