The Michigan Instruments’ Breath Simulation Module is a compact precision device designed to transform the dual adult Training and Test Lung into a spontaneously breathing system. While in this mode, the PneuView system can analyze a simulated patient breath at preset compliances and resistances as well as investigate the characteristics of assisted ventilation. No other apparatus allows for simulated breaths at such a controllable level. Use of a Breath Simulation Module allows for: A physical and digital display of spontaneous breaths, useful in the classroom and in ventilator calibration. Accurate control of breath rate, tidal volume and inspiratory time. Easy, calibrated ventilation of testing equipment via line-air. Simple setup. With a Breath Simulation Module, a spontaneously breathing system can be set up in less than two minutes.
