Connect the water tube from the water inlet (backflow)
[9]
to the water outlet
of the oxygenator.
NOTE: Ensure that the Hansen couplings are correctly connected to the water
inlet and outlet of the respective heat exchangers. The couplings are coded
with symbols for the patient water circuit and for the direction of flow.
3
Open the stopcock
[1]
of the patient water circuit P1.
▶
The handle is in the vertical position: The stopcock is open.
4
Ensure that the stopcocks that are not part of a water circuit are closed.
5
WARNING! Ensure that the oxygenator heat exchanger is connected to the
patient circuit P1.
De-air the patient water circuit (⇨ "De-airing the Circuits", page 56).
Connecting the cardioplegia heat exchanger to the CPLG water circuit
WARNING!
n
Before use, check the pressure resistance of the heat exchanger, as shown
on the manufacturer's data sheet.
n
The heat exchanger used must be approved for a water flow of at least 2 l/
min.
WARNING!
n
The tubes of the perfusion system used should not be too long.
n
Insert the external temperature sensors (optional) fully into the measurement
device in the perfusion system and lock into place.
