Fig. 1From: Physiological effects of invasive ventilation with neurally adjusted ventilatory assist (NAVA) in a crossover studyStudy design. Baseline measures were collected when patient met stability conditions. No changes in PEEP, FiO2, sedation nor inotropic doses were allowed during the two 30-min study periods.
