Fig. 1From: Severe but reversible impaired diaphragm function in septic mechanically ventilated patientsA Endotracheal tube pressure induced by bilateral phrenic nerve stimulation during airway occlusion (Ptr,stim) at inclusion (< 24 h of intubation) and at the second measure (pressure support mode) in septic and non-septic patients. p identified by Wilcoxon matched-pairs test. B Relative changes (%) in endotracheal tube pressure induced by bilateral phrenic nerve stimulation during airway occlusion (Ptr,stim) between the two measurements (inclusion and pressure support mode) in septic and non-septic patients. p identified by Mann–Whitney test. C SOFA score at inclusion (< 24 h of intubation) and at the second measure (pressure support mode) in septic and non-septic patients. p identified by paired t test. D End-expiratory diaphragm thickness measured by ultrasound at inclusion (< 24 h of intubation) and at the second measure (pressure support mode) in septic and non-septic patients. p identified by Wilcoxon matched-pairs test.
