Designed by Convergent Engineering, FDA cleared VentAssist™ uses machine intelligence to simplify mechanical ventilation by focusing on optimizing oxygenation, ventilation, patient effort, and lung protection. Convergent's patented techniques for calculating plateau pressure and patient work of breathing  (neural network) are combined with standard parameters and used in a fuzzy logic system to guide therapy. VentAssist recommends new ventilator settings and provides rationale for the changes. Philips Healthcare has licensed and commercialized VentAssist.
