Correlation between pendelluft volume and regional ventilation delay. At the lowest pressure support ventilation (PSV) level, pendelluft volume positively correlated with the percentage of lung zones affected by ventilation delay (RVD) in the high-pendelluft group (p = .04, r = .69, empty circles), but not in the low-pendelluft group (p = .65, filled circles). While in the high-pendelluft group a high regional ventilation delay value was associated with the presence of pendelluft, some patients in the low-pendelluft group showed high regional ventilation delay values but low pendelluft volumes
