We developed a computer assisted program for training the medical staff in ventilating newborn infants. The Java-based client-server program consists of two modules: the instructor module enabling the domain expert to create courses of virtual patients, the tutorial module running consultations with virtual patients. The tutorial module displays the course of the transcutaneous blood gases and a table of the ventilator settings which can interactively be adjusted by the trainee to provide an adequate gas exchange to the virtual patient. VIE-NVT is currently tested at our neonatal intensive care unit.
