During the operation as the actual deficit climbs, the LEDs will light up sequen-
tially representing the actual deficit volume until the deficit limit is reached. (See
Section
Deficit Limit
in Chapter 6, Safety functions).

Using the Pump during Operation
Open bag clamps (
(3)
Figure 5-10).
Fully open hysteroscope inflow stopcock.
Press the
Prime
button (
(17)
Fig. 5-1).
Pump will run for approximately 20 seconds to purge air from tubing and
run the Automatic Lumen Calibration.
Pump will display
Calibration Running.
Automatic lumen calibration
The pump is equipped with an automatic lumen calibration functionality. The
system determines the flow resistance of the hysteroscope. This resistance is
used to calculate the pump pressure necessary to maintain the pre-set intrauter-
ine pressure. In order to overcome this resistance the pump allows pressure of up
to 80 mmHg during calibration. This is indicated in the Intrauterine Pressure dis-
play. In case calibration fails due to high resistance it will be repeated allowing
pressure of up to 150 mmHg. If it still cannot be completed the pump will show
Prime Fail -Open Stopcock, Clamps
.
The automatic lumen calibration starts once the
Prime
button is pressed.
Once Automatic Lumen Calibration is completed, pump will beep three
times. The pump display will show
Prime Successful Close Stopcock
for 5 secs
followed by
System Operating.
Close hysteroscope inflow stopcock to stop fluid flow. Once all fluid has been
removed from the drape, zero the deficit display.
NOTE!
The pump continues to operate after automatic lumen calibration is complete.
The pump should be stopped by closing hysteroscope inflow stopcock.
NOTE!
Automatic lumen calibration has to be performed each time a different hystero-
scope is used during the procedure by pressing the Prime button.
System Operation
Open stopcock and guide the hysteroscope with fluid flowing into the uter-
us.
Adjust intrauterine pressure setting as necessary to obtain adequate disten-
sion and visualization.
Completing System Operation
After system operation is complete, close the hysteroscope inflow stopcock.
Wait until the entire fluid volume in the under-buttock drape and the tube
set has been has been collected into the canisters.
Press the
Pause/Resume
button.
Record the deficit volume on the deficit display. This is the total fluid volume
that was absorbed by the patient.
WARNING!
Device error: Do not use the Aquilex System if a defect is suspected or detected
during the function check. This also applies to obvious and visible defects, espe-
cially defects and damage of the power plug and power cord.

Changing Canisters during Procedure
Changing canisters during the procedure
Pause the pump by pressing
Pause/Resume
button.
This locks the fluid deficit display number.
Remove desired canisters and install new canisters.
