Gas flow rate
Surgical procedures must be brought to completion with insufflators having the capacity to
achieve flow rates of between 4 and 10 l/min. Insufflators with lower flow rates must only be
used for diagnostic procedures.
Gas coagulation systems
Some medical devices while introducing gas into the peritoneal cavity during surgical laparos-
copy (gas lasers, for example) can bring about excessive abdominal pressure. If venous sinuses
are formed and an embolism is caused, the use of a secondary source of gas that is distinctly
less soluble in blood than CO2 can cause a rapid increase in intra-abdominal pressure. The
use of these coagulation systems during laparoscopic procedures is entirely the responsibility
of the practitioner.
Bacterial filter
The use of a hydrophobic bacterial filter is essential for avoiding cross-contamination between
patients.
The potential equalisation plug located at the back of the medical device can be used to equa-
lise the grounding potential of the medical device with that of all the apparatuses plugged into
the power main in the environment. Use the shared grounding system in the hospital or the
building.
Connect the potential equalisation cable to the equipotential socket C7 at the back of the ap-
paratus.
Apparatuses connecting to the input/output ports must comply with the IEC 60950-1 stan-
dard.
