Operating Modes of the PNEUMOCLEAR™ Insufflator
48 / 77
WARNING!
Hypercapnia
Because pediatric patients are especially susceptible to hypercapnia, it is recom-
mended to establish an end-tidal CO
2
monitoring routine.
6.4 Advanced Flow Operating Mode
The
Advanced Flow
operating mode is used to distend the peritoneal cavity during
laparoscopic procedures, including but not limited to robotic-assisted laparoscop-
ies by insufflating CO
2
. The Advanced Flow operating mode is designed to com-
pensate for large leaks e.g. due to the use of suction instruments.
Patients
The
Advanced Flow
operating mode is designed for laparoscopies performed on
normal weight and obese patients over the age of 14.
The
Advanced Flow
operating mode may be used for a number of different proced-
ures, including but not limited to:
• Prostatectomy
• Hysterectomy
• Gastrectomy
• Colectomy
• Nephrectomy
Insufflation parameters
The maximum nominal pressure can be set to 30 mmHg and the maximum gas
flow to 50l/min.
6.5 Vessel Harvest Operating Mode
The
Vessel Harvest
operating mode is used to distend the cavity along the vena
saphena magna and radial artery during an endoscopic vessel harvesting proced-
ure.
Patients
The
Vessel Harvest
operating mode is designed for patients over the age of 14.
Insufflation parameters
The maximum nominal pressure can be set to 20 mmHg and the maximum gas
flow to 10l/min.
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
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
2
is always ab-
sorbed through the tissue of the patient during insufflation (intravasation). This
means the body absorbs part of the CO
2
gas used for insufflation. CO
2
concentra-
tions 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 pa-
tient 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.
