Objectives
Narrative objectives1 Lung-protective mechanical ventilation with the use of lower tidal volumes is beneficial for patients with ARDS and without ARDS. However, there is little evidence about a specific amount of tidal volume less than 10ml/kg/PBW. Achieving 6ml/kg/PBW of tidal volume without neuromuscular blockade is sometimes interrupted by the patients-ventilator asynchrony (PVA).
PVA is defined as a mismatch between the patient breathing efforts with a ventilator's breath delivery. A higher incidence of PVA is significantly related to ICU mortality. Reverse triggering (RT) is one of the types of PVA, which is defined as the inspiratory effort due to the mandatory breathe by a mechanical ventilator. RT is a notable phenomenon because the incidence of RT is almost fifty percent of mechanically ventilated ARDS patients and RT may exacerbate the lung injury. Lower tidal volume may also relate to the incidence of RT according to a prospective multicenter observational study.
Therefore, this study aims to investigate the incidence of RT in mechanically ventilated patients receiving 6ml/kg/PBW compared to 7.5 ml/kg/PBW.
Basic objectives2 Others
Basic objectives -Others This study aims to clarify the incidence of RT in mechanically ventilated patients with acute respiratory failure (PaO2/FIO2 < 300mmHg) including ARDS, comparing 6 ml/kg PBW of tidal volume with 7.5 ml/kg PBW.
