4.6.2 Check Before Every Application
WARNING!
Ensure that all the following requirements are met before every use:
n
The self-test completed without any error when the system was switched on (
⇨ "Switching On the HCU 40, Self-Test", page 43).
n
The size of the ice blocks is sufficient.
n
Crushed ice is available.
n
There are no leaks in the water tubes or tube connections or heat
exchangers.
n
The water flow is sufficient.
n
The water level in the tank is within the required range.
n
The values of the (optional) external temperature sensors are plausible.
System test
n
The alarm functions are functioning correctly (⇨ "Testing Alarm Functions",
page 69).
Connectors
n
The Instructions for Use for the employed heat exchangers have been
observed. In particular the connection requirements, e.g., direction of flow and
maximum possible pressure.
n
The set pressure limits for the circuits are equal to or lower than the
permissible maximum pressure for the heat exchangers (⇨ "Displaying the
Pressure Limits", page 68).
n
The patient circuit and cardioplegia water circuits are correctly connected:
–
the patient water circuit is connected to the oxygenator heat exchanger.
–
the cardioplegia water circuit is connected to the cardioplegia heat
exchanger.
