2) Perfuse through the aortic cannula as required
by the patient's condition, slowly decreasing the
level in the cardiotomy/venous reservoir.
3) If desired, blood in the oxygenator may also be
returned by adding clear prime to the venous
reservoir when the blood in the reservoir as
reached minimum value. Pump the prime
slowly (minimum flow ~50 ml/min) through the
oxygenator ensuring that the reservoir never be
emptied.
4) When the cardiotomy/venous reservoir is nearly
empty, stop the arterial pump and clamp the
arterial line.
USE OF THE ACTIVE VENOUS DRAINAGE
WITH VACUUM (VAVD)
The device can be used for vacuum-assisted
drainage as it is fitted with a pressure rilef valve.
To safely apply a vacuum to the device, carefully
read the instructions for use in this point.
CONNECTING THE VACUUM LINE
If performing venous drainage using the vacuum
technique, the vacuum line must be connected
to the port marked "VENT/VACUUM PORT" after
removing the label and yellow protection cap.
Connect the Eurosets connection kit (VAVD) to it.
Connect the other end of the line to a vacuum
regulator equipped with a condensation trap.

WARNINGS
• Do not apply the vacuum during PRIMING AND
RECIRCULATION PROCEDURE.
• It is recommended not to exceed -75.2 mmHg
(-10 KPa) when applying negative pressure to
the cardiotomy/venous reservoir.
• Periodically check functioning of the vacuum
If is necessary to interrupt vacuum application,
remove one of the leakproof caps on the cardiotomy/
venous reservoir and remove clamp from the
collecting line to the suction source for the VAVD
tecnique.
In case of vacuum-assisted drainage (VAVD),
re-insert leakproof cap on the cardiotomy/venous
reservoir and re-insert the clamp on the collecting
line to the suction source.

CAUTION
During the vacuum-assisted venous drainage
procedure pay attention to involuntary opening of
the luer locks or ports positioned on the turret,
as this causes a reduction of the vacuum in the
reservoir; open the ports only when fluids need to
be sent to the venous reservoir and only for the time
necessary for this operation.
