摘要: This study classifies the mode of ventilation using respiratory rate, inhaled and exhaled carbon dioxide concentrations in anaesthetised patients. Thirty seven patients were breathing spontaneously (SPONT) 50 on a ventilator (intermittent positive pressure ventilation, IPPV). A data-based methodology for rule inference from trained neural networks, orthogonal search-based extraction, identified two sets low-order Boolean rules differential identification ventilation. Combining both models produced three possible outcomes; IPPV, SPONT 'Uncertain'. The true rates approximately maintained at 96% IPPV 93% SPONT, with false 0.4% each category 4.3% 'Uncertain' inferences.
