ion techniques to validate and smooth the input data. In addition to providing treatment advice to clinicians, several IDSSs can also be used for closed-loop control of ventilation and/or weaning, while others are strictly open-loop knowledge-based

Recent major advances in mechanical ventilation have resulted in new exciting modes of assisted ventilation. Compared to traditional ventilation modes such as assisted-controlled ventilation or pressure support ventilation, these new modes offer a number of physiological advantages derived from the improved patient control over the ventilator. By implementing advanced closed-loop control system...

This paper briefly considers the application of the principles of Empirical Modelling to an analog mechanical computer of WWII, and puts forward the theory that this primitive early computer, that followed such different principles to today's all-purpose computers, had properties of its design in common with EM models. The computer and system in question are related briefly to the principles of...
