(a) Disconnect the green patient-breathing tube from the 500cc in-line
(b) Install a flow test device (P/N 4418) to the nebulizer outlet with the
orifice pointing away from the nebulizer.
(c) Adjust the nebulization control to maximum and refer to Table 2-2
for the flow parameters.
(d) Remove the flow test device and reconnect the tubing to the
(a) Disconnect the green nebulizer jet line from the outlet in the bottom
of the ventilator. Install the male adapter of a 0 to 60psig nebulization gauge (P/N 6758)
into the nebulizer jet outlet and connect the female adapter of the gauge to the nebulizer
(b) Set the flow for 10 lpm. The maximum setting on the nebulizer
control should indicate 12 to 16psig. The minimum setting should drop gauge pressure
to between 2 to 6psig.
(c) Disconnect the test gauge and reconnect the nebulizer jet line into
the base of the ventilator.
(a) Ensure the outflow valve is fully OPEN (clockwise). The airway
manometer should register between 2 to 4cmH2O.
(b) Rotate the expiratory flow control knob fully counterclockwise. The
sub-ambient pressure observed on the manometer should register at least -10cmH20.
Rotate the expiratory-flow knob fully clockwise to OFF.
Outflow valve (CPAP control).
(a) Adjust the flow for 15 lpm. Rotate the red control lever fully
counterclockwise and observe the manometer for a CPAP of at least 20cmH20.
(b) Rotate the red control lever back to a minimum setting (fully
