Fig. 5From: A new way of monitoring mechanical ventilation by measurement of particle flow from the airways using Pexa method in vivo and during ex vivo lung perfusion in DCD lung transplantationDifferent drugs were injected into the ex vivo lung perfusion (EVLP) circuit. Distribution of different particle sizes at a baseline, and after injection of b potassium (K), c norepinephrine (NA), and d niprid. Note the differences in the total amount of particle count in the different settings; interestingly, the same particle size distribution was seen in all the settings. Volume-controlled ventilation (VCV) with small tidal volumes 6–8 ml/kg, breathing frequency at 16, and PEEP at 2 (VCV1) was used during all settingsBack to article page
