Different 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 settings
