ATELECTASIS
The assessments for measuring ventilatory mechanics and oxygenation were performed on the first day of each participant’s inclusion in the study. These assessments took place at five time points in both groups: before the usual care (A1), 5 minutes after the usual care (A2), 5 minutes after the interventions in the intervention group (or after a 20-minute interval in the control group, comparable to the duration of the interventions) (A3), and 30 minutes after the interventions (A4).At the end of the hospital stay or death, an evaluator blinded to the participant’s allocation and outcomes of ventilatory mechanics and oxygenation assessed the following outcomes: incidence of atelectasis, length of hospital and ICU stays, duration of mechanical ventilation, extubation success, and in-hospital mortality.
