Fig. 5

Inspiratory pressure–time product of the diaphragm per minute (PTP DI /min) in the two groups of patients, ventilated in neurally adjusted ventilatory assist (NAVA) or pressure support ventilation (PSV). White bars denote the PTPDI/min recorded each 4 hours during NAVA; black bars denote the PTPDI/min recorded each 4 hours during PSV. Dotted red lines denote the physiological PTPDI/min range according to a previous publication [42]
