Bench Performance Checks—Breathing Simulator
BENCH PERFORMANCE CHECKS—BREATHING SIMULATOR
The performance checks shown on page 35 through page 37 were
measured by use of a breathing simulator.
WARNING:
Due to excessive restriction of valves in the Controller, reduced
performance levels may result when gas supply pressures
< 50 psi (345 kPa) are used.
For these checks, we used a compressed gas supply of 50 to 55 psi
(345 to 379 kPa). The breathing simulator was configured with different
compliance and resistance values to represent different degrees of lung
health.
