From: Automatic versus manual pressure support reduction in the weaning of post-operative patients: a randomised controlled trial

Figure 3

Pressure support ventilation (PSV) level variation throughout weaning. Each PSV refers to increments of 30 minutes in the weaning process. There was a significant difference between the automatic mode and the manual mode of weaning (p < 0. 01). The numbers at the bottom of the figure refer to the number of patients that stayed in the weaning trials through time.
