HALES [Heart And Lung Equipment Simulator] represents a paradigm shift in perfusion simulation away from the now obsolete Hydraulic Perfusion Simulators (HPS).
The paradigm shift is that HALES is not just a simulator but a full featured perfusion system INTERFACE. It has a full range of hydraulic connections to the Heart-lung machine, and connects as does a cannulated patient.The increasing use of ECMO in the ICU has generated a need for a flexible and multi-configurable patient. The sort of flexibility that HALES provides.
HALES can be used with as many or few patient connections as the situation dictates which generates a flexibility and utility not had by the old HPS. From there on the new paradigm takes over to provide an educational experience which is only limited by the syllabus and the imagination!
