Safety functions
The device is equipped with an automatic venting system.
When the insufflator detects an overpressure it automatically activates the vent-
ing system. The venting system releases gas from the abdomen or from the ves-
sel until the set nominal value has been reached again.
The function "Automatic venting system" can be activated/deactivated in the
Configuration menu.
CAUTION!
Please note that the automatic venting system is only active during the Veress
insufflation mode if "In Veress insufflation ON" has been set in the configuration
menu (only possible in Pediatric operating mode, see chapter 7 Using and Con-
trolling the PNEUMO SURE High Flow Insufflator in Pediatric Operating Mode,
page 34).
WARNING!
The venting rate of the automatic venting system is limited. Always monitor the
actual pressure when using additional insufflation sources.
The manufacturer advises against using additional, non-pressure controlled in-
sufflation sources during minimally invasive surgical procedures.
The self-inflating property of lasers cooled with CO2 and argon beamers can lead
to values exceeding the recommended and safe pressure rating.
After 2 to 5 seconds (depending on the setting in the Configuration menu), the
display depicts Venting system active when the nominal pressure has been ex-
ceeded by 2-5 mm Hg.
If the overpressure cannot be reduced by the automatic venting system within 5
seconds, the display depicts Overpressure followed by Venting system active. An
acoustic alarm is emitted.
Once the nominal pressure limit has been reached/exceeded (High Flow/Bariat-
ric -> 30 mm Hg or Pediatric/Vessel Harvest -> 20 mm Hg), the display depicts the
message Overpressure. A warning signal is emitted at the same time.
