Indications of the Flow 50 Insufflator
WARNING!
Idiosyncratic reactions
Patients with sickle cell anemia or pulmonary insufficiency may have a higher
risk of metabolic imbalance related to excessive CO absorption (idiosyncratic
2
reaction).

WARNING!
CO absorption
2
Due to the special surgical procedures - start of the heart bypass operation, and
the endoscopic removal of the vessel - special care has to be taken as CO is al-
2
ways absorbed through the tissue of the patient during insufflation (intravasa-
tion). This means the body absorbs part of the CO gas used for insufflation. CO
2 2
concentrations in the blood or respiratory 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 . High pressure or a high gas flow promotes CO absorp-
2 2
tion.
WARNING!
Metabolic and cardiac reactions
Insufflating CO may result in metabolic acidosis. This can lead to cardiac irregu-
2
larities expressed with the following symptoms:
• Reduced respiration with restricted diaphram function
• Hypercapnia
• Reduction of venous reflux
• Reduced cardiac output
• Metabolic acidosis
WARNING!
Dehydration
Insufflation can lead to dehydration of the tissue. This can result in organ tissue
damage and cardiovascular reactions of the patient. Long surgeries and large
leaks increase the risk of dehydration (especially at the insertion points of the
trocars or when changing instruments).
WARNING!
Embolism/insufflation of internal organs
Improper placement of the insufflation instrument could cause gas penetrating
a vessel or an internal organ, resulting in air or CO embolisms. To reduce the
2
risk, use a low flow rate for the first insufflation and ensure that the insufflation
instrument is correctly positioned. Check the position of the insufflation instru-
ment immediately if the actual pressure rapidly reaches the nominal pressure
value. CO embolisms can also be caused by a high intra-abdominal pressure.

Avoid high-pressure settings and close damaged blood vessels at once.
