3.3.2 Warnings Standard and High Flow/Bariatric Operating Mode
WARNING!
Idiosyncratic reactions
Patients with sickle cell anemia or pulmonary insufficiency may have a higher risk
of metabolic imbalance related to excessive CO2 absorption (idiosyncratic reac-
tion).
WARNING!
CO
2
absorption
CO
2
is absorbed during insufflation (intravasation). This means the body absorbs a
part the CO
2
gas used for insufflation. CO
2
concentrations in the blood or respirat-
ory system that are too high can lead to death of the patient in extreme cases. To
lower this risk, always carefully and closely monitor the patient's vital signs during
the entire insufflation process and make sure patient is breathing well. Sufficient
respiration can help avoid or limit problems with CO
2
. High pressure or a high gas
flow promotes CO
2
absorption. The abdomen is sufficiently distended using a pres-
sure between 10 to 15mmHg. Pressure values above 15 mmHg are required for
only a few cases but do increase the risk of intravasation. Never exceed the max-
imum intra-abdominal pressure of 30mmHg.
WARNING!
Metabolic and cardiac reactions
Insufflating CO
2
may result in metabolic acidosis. This can lead to cardiac irregular-
ities expressed with the following symptoms:
• Reduced respiration with restricted diaphram function
• Hypercapnia
• Reduction of venous reflux
• Reduced cardiac output
• Metabolic acidosis
WARNING!
Hypothermia/monitoring body temperature
The gas flow can lead to a lowering of the patient's body temperature during insuf-
flation. Hypothermia during insufflation can cause heart and cardiovascular prob-
lems. The risk for hypothermia can be significantly reduced with the use of gas that
is pre-warmed to body temperature. Therefore, you must always monitor the pa-
tient's body temperature during the entire insufflation process. Make especially
sure that the following, hypothermia-fostering, surgical conditions are avoided as
best as possible:
• High gas flow due to large leaks
• Long surgeries
• Use of irrigation and infusion solutions that are not preheated to body temperat-
ure.
