The automatic change-over must be selected on the surgeon's orders.
Press the "STOP" button to halt insufflation.
6.5 COnTROls
When the pneumoperitoneum has been created at the required pressure, the insufflator will
keep this cavity at the pressure selected and will immediately compensate for any leakage of
CO2.
The high-flow mode must be activated in order to benefit from maximum reactivity from the
insufflator.
When the determined pressure has been reached, the insufflator will stop insufflating. The insuf-
flator will resume as soon as the pressure in the cavity falls below the pressure selected.
Control the pressure in the trocar during gas input.
6.6 eXCessiVe PRessURe
As soon as the instantaneous pressure in the cavity exceeds the pressure setpoint by 2 mm Hg:
- The message "EXCESSIVE PRESSURE" is displayed on the screen.
The insufflator then opens the external desufflation valve to lower the pressure in the cavity.
As soon as the pressure in the cavity exceeds the pressure setpoint by 5 mm Hg:
- The instantaneous pressure display turns orange
The insufflator then opens the external desufflation valve to lower the pressure in the cavity.
6.7 PARAMeTeRs
The instantaneous flow is shown on the screen in litres/minute.
The volume of gas used is shown in litres on the screen (accurate to the decilitre. For illustrative
purposes only.)
This measurement begins at the same time as insufflation and is only reset to zero when it reini-
tialises each time the apparatus is started up (or from the parameters interface menu).
If necessary, set it to zero using the menu.
Only use medical-grade CO2 for coelioscopy, in accordance with European standards.
