Two-node decision tree model. (a) Describes the two nodes of the decision model: (1) treat with Neurally Adjusted Ventilator Assist (NAVA) or pressure support ventilation (PSV), and (2) patient is synchronous or asynchronous. (b) Described the adjustable model input parameters (shown in orange) and the model output parameters (shown in blue). In addition to adjusting the proportion of patients with asynchrony index of at least 10% and costs, the duration of mechanical ventilation (MV) for synchronous and asynchronous patients can be adjusted from the default, originating from the de Wit et al. (2009) study. ICU, intensive care unit.
