Fig. 3From: Assisted mechanical ventilation promotes recovery of diaphragmatic thickness in critically ill patients: a prospective observational studyDiaphragm thickening fraction over time. Diaphragm thickening fraction was lower during the days before day 0 (corresponding to the time spent by the patient ventilated in controlled modes) than during the days after day 0 (corresponding to the period spent with assisted ventilation modes)Back to article page
