4 Ensure that the stopcocks that are not part of a water circuit are closed.
5 WARNING! Ensure that the cardioplegia heat exchanger is connected to the
cardioplegia water circuit.
De-air the cardioplegia water circuit (⇨ "De-airing the Circuits", page 56).
Connecting the warming/cooling blanket to the water circuit P2
WARNING!
n When operating the warming/cooling blanket, use a pressure reducer to
reduce the pressure to the permissible level for the warming/cooling blanket;
or only operate the warming/cooling blanket in addition to a water circuit with
a connected oxygenator heat exchanger or the supplied pressure reducer to
avoid overpressure in the warming/cooling blanket.
n Place a dry, absorbent sheet with a moisture barrier on the warming/cooling
blanket to protect the patient against any leakage from the blanket.
n The warming of transdermal medication (e.g. plasters) may increase the
amount of active ingredient administered, and so harm the patient.
n When the HCU 40 is off, it is possible that the patient's body temperature will
fall.
n Only connect the warming/cooling blanket with the short tubes intended for it
((⇨ "Accessories", page 133), 6 m (3 m + 3 m)) in order to minimize the
deviation between the setpoint and actual temperature of the warming/cooling
blanket.
Indications
To prevent or treat hypo/hyperthermia.
Use of the warming/cooling blanket with the heater-cooler unit HCU 40 helps to
regulate the patient's body temperature. For this purpose, temperature-controlled
water is passed through a hypo/hyperthermia warming mat via a connection tube.
This mat acts as the interface that either keeps the patient warm or cool. Its
temperature is adjusted to a preset value by the heater-cooler unit.
NOTE
Observe the corresponding Instructions for Use when connecting and using the
warming/cooling blanket.
