From: Impact of prolonged assisted ventilation on diaphragmatic efficiency: NAVA versus PSV
Neuro-ventilatory efficiency (NVE) and neuro-muscular efficiency (NME) recorded during the spontaneous breathing trial at 0, 24 and 48 hours in the two groups of patients, i.e., randomized to be ventilated in neurally adjusted ventilatory assist (NAVA) or pressure support ventilation (PSV). The NVE and NME trends were significantly different (analysis of variance model; F = 15.32; p <0,0001 for NVE and F = 5,15; p = 0.033 for NME). *Significant difference compared to 0 hours (within-group post-hoc comparison). #Significant difference compared to 24 hours (within-group post-hoc comparison). §Significant difference compared to the same time (between-groups post-hoc comparison)
