Real-Time Estimation of Alternative Stress Index for Low-Cost, Mechanical Ventilators for Emergency Use

Stress index is a useful indicator in mechanical ventilation to assess improper ventilation settings. It can indicate tidal overdistension or tidal recruitment, which are two major mechanisms of ventilator-induced lung injury. However, it’s implementation require dedicated hardware and software and is not a widespread parameter used in commercial ventilators. In this work, an alternative, simple w...
