Fig. 6From: 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 transplantationDPPC and PC concentrations were measured in exhaled particles in four of the animals and were expressed as weight percent (wt%). The amount DPPC in percent (wt%) of total Pex sample is shown in a. Note the significant increase in DPPC in EVLP late phase as compared to in vivo (p = 0.04). No differences were observed in the PC wt% of total Pex sample, as shown in bBack to article page
