 Use of SI monitoring in isolated and perfuse lung reconditioning, may be an useful tool to prevent hyperinflation and opening-closing conditions by titrating optimal protective ventilation As previously reported by our group, in the first trial of lung reconditioning, signs of mechanical stress were detected with Paw-t curve. 3 Therefore we implemented EVLP procedure with continuous stress index analysis to detect and quantify the occurrence of hyperinflation or opening closing condition.
