Set the FLOW SETTING for a flow slightly LESS than the
flow that the insufflator can provide.
Push the MANUAL button.
Observe the effect of a complete cycle by noting the
pneumoperitoneal pressure on insufflator gauge/indicator
before the CRYSTAL VISION
immediately after the pump stops. The intra- abdominal
pressure should not drop more than 1-2 mmHg. If it does,
reduce the flow on the CRYSTAL VISION
SETTING and repeat the process until the pressure drops
very slightly. It is important to set the CRYSTAL VISION
flow as high as possible without diminishing the
pneumoperitoneal pressure.
The FLOW SETTING indicates the desired
maximum Flow.

at that moment. The meter will read zero
when the pump is off.

3. The MANUAL button can be used to start the vacuum
pump if smoke still exists when the TIME SETTING is
set for the maximum amount of time. Be sure to monitor
the pneumoperitoneal pressure so that it does not fall more
than a few mmHg (adjust the FLOW SETTING, if
necessary).
OPERATIONAL HINTS:
The TIME SETTING can be used to
conserve insufflator gas by reducing the
amount of time that the Crystal Vision
pumps after lasing stops.

lamp and audio indicators turn ON. If the pressure
exceeds 30 mmHg (±10% and 1 digit) the CRYSTAL

pressure situation.
