Heater Cooler Unit Usage: The Heater-Cooler Unit (HCU 30) supplies temperature-controlled water for cardioplegia heat exchangers and for blood heat exchangers in extra corporeal circulation and for blankets with which patients can be warmed or cooled. The HCU 30 is intended to circulate water through heat exchange circuits to warm or cool a patient during short duration cardiopulmonary bypass procedures lasting 6 hours or less.

Reason: There is the potential for contaminated water to enter parts of the Heater-Cooler Unit circuits. There is a potential risk of bacterial contamination including Mycobacteria species.
