Reimers Systems, INC

Operating Environment	* Indoors * In normal air environment * Can be placed inside a Hyperbaric chamber where an 80 volt dc motor is acceptable * The lung module can also be placed outside of a hyper-baric chamber with pipes run-ning into the chamber to the apparatus. When used in this way, the maximum internal working pressure is 100 psig.
Standard Breathing Waveforms	* 15 liter per minute (lpm) sine wave1.0 l tidal volume, 15 bpm * 22.5 lpm sine wave 1.5 l tidal volume, 15 bpm * 40 lpm sine wave 2.0 l tidal volume, 20 bpm * 50 lpm sine wave 1.0 l tidal volume, 50 bpm * 90 lpm sine wave 3.0 l tidal volume, 30 bpm * 30 lpm square wave 2.0 l tidal volume, 15 bpm
Other Breathing Waveforms	Almost any physiologically reasonable waveform can be programmed using the "contouring" capabilities of the motion controller
Tidal Volume	0 to 3.0 liters
Flow Rate	0 to 283 liters/minute
Piston Displacement	* 0.44 liters/inch * 18223 motor encoder TTL counts/liter
Power Requirements	* 115 vac, 15 amps, 60 hz or * 220 vac, 8 amps, 50/60 hz
Standard Instrumentation	* Piston position transducer, analog output * Motor position encoder * Breathing pressure transducer
Data Acquisition	* Analog to Digital board: 8 analog inputs, 4 KHz. * Commercial data acquisition software for laboratory type applications
Data Analysis Software	Microsoft Excel with RSI's breathing resistance spread- sheet for analyzing and summarizing typical breathing resistance test data.
Dimensions	* Lung Module: 37.5" lg. (953mm) x 15.5" wd. (394mm) x 11.0" ht. (279mm) * DAC Module: 25.7" lg. (654mm) x 20.7" wd. (527mm) x 8.4" ht. (213mm) * Computer: varies per application
