Activating Gradient mode
NOTE
Only use for support
The ambient temperature and behavior of the heat exchanger can affect the
functioning of the Gradient mode and lead to inaccuracies.
n
Consequently, the Gradient mode should only be used as a supporting
function and you should additionally monitor the patient temperature.
n
Monitor the temperature of the patient with an independent monitoring and
alarm system.
The HCU 40 requires the measured values from the external temperature sensors
for the Gradient mode.
The Gradient mode is automatically deactivated for circuits where no external
temperature sensors are connected.
You can activate the Gradient mode for the patient and cardioplegia water circuit
independently of each other.
1
▶
The touchscreen displays the temperatures (T
ext
) measured externally for
the patient and cardioplegia water circuit as well as fields for the gradients
(ΔT) (⇨ "Parameter Display", page 27).
NOTE: Also follow the instructions for use of the disposable being used.
2
For the patient water circuit connect the temperature sensor in the venous line
or to the venous reservoir.
Or
For the cardioplegia water circuit connect the temperature sensor to the
cardioplegia heat exchanger.
3
Touch the symbol of the corresponding circuit.
