Progress of respiratory variables in pigs. Unadjusted data presented as median [interquartile range]. (A) Electrical activity of the diaphragm in microvolts. (B) Esophageal pressure swing in cm H2O. (C) Tidal volume in ml/kg of predicted body weight. (D) Peak transpulmonary pressure in cm H2O. (E) Driving pressure in cm H2O. After lidocaine administration, all variables progressively decreased over time. *Corrected P < 0.05 when compared to baseline.
