How long do you strictly enforce low tidal volume ventilation in ARDS?
Median duration of mechanical ventilation in the ARMA trial was 8 days. For example, it is often necessary to balance sedation needs with ventilator dyssynchrony later in the course of ARDS. Is there any data to inform that tight control of tidal volume 4-6 cc/kg helps outcomes after more than 8 days of mechanical ventilation?

I do not believe that there is data specifically looking at during duration of LTVV in ARDS vs shorter durations. However, there are multiple trials that argue that LTVV in ARDS and patients at risk for ARDS improves mortality outcomes with minimal negative side effects. In my practice, I try to adh...

I use low tidal volumes throughout the entire course of ventilation in patients with ARDS as well as those with non-ARDS acute hypoxemic respiratory failure (AHRF). It is important to note that while the target tidal volume in the lung protective ventilation (LPV) group of the ARMA trial was 6 mL/kg...
