Troubleshooting 6-3
Table 6-1 EX3000 Anesthesia System Problem – Solution Matrix (continued)
No. Problem Cause Solution
5 Needle on system
pressure gauge
(Figure 1-5, 3)
indicates a negative
pressure a. Excessive
scavenger
system vacuum
Decrease scavenger system vacuum. Recommend
a scavenger interface valve to prevent removal of
patient gases. Also see items 9c and 10c.
b. Inadequate fresh
gas flow
Increase fresh gas flow rates.
6 Patient sleep level
seems too light a. Vaporizer is
empty
Fill vaporizer with the appropriate anesthetic.
b. Anesthetic
concentration is
set too low
1. Press the anesthetic agent concentration
section (Figure 1-5, 2) on the touch screen.
2. Press
S
or
T
until the desired concentration is
displayed.
c. Leak in patient
breathing circuit
Perform a System Pressure Leak Test as specified
below.
d. Excessive CO

build-up
1. Check CO2 absorbent and replace if necessary.
2. Check proper function of inspiration and
expiration valves (Figure 1-3).
e. Leak around the
vaporizer filler
port
1. Remove the filler plug.

touch screen.
b. Vaporizer
malfunction

the base of the flowmeter on the touch screen and
press the decrease button
T until the desired flow
rate is displayed.
c. Scavenger
system suction is
set too low or is
occluded
Increase vacuum flow for scavenger suction or
install a scavenger interface valve vented to
atmosphere.
9 Gas is flowing , but
breathing bag does
not inflate a. Breathing bag is
punctured
Replace breathing bag and mount the new bag
securely on the bag mount (Figure 1-3, 13)
b. Pop-off valve is
completely open
Turn the knob on the pop-off valve clockwise until
the bag starts to inflate.
c. Scavenger
system suction is
set too high
Decrease scavenger system suction.
or
Install a scavenger interface valve vented to
atmosphere.
