Study information
Scientific title
High frequency oscillation versus lung-protective ventilation using conventional ventilators to reduce Acute Respiratory Distress Syndrome (ARDS) mortality: a randomised, parallel, two armed, multicentre pilot trial
Acronym
OSCILLATE Pilot
Study hypothesis
This is a pilot study to test the feasibility of a larger trial for which we hypothesise that high frequency oscillation will reduce acute respiratory distress syndrome (ARDS) mortality compared to lung-protective ventilation using conventional ventilators.
Ethics approval

Primary outcome measure
1. Feasibility at one-year of study. The three feasibility outcomes for the OSCILLATE pilot study will be evaluated as follows:
1.1. We will consider adherence to our explicit mechanical ventilation protocols to be adequate if more than 80% of patients (approximately 24/30) have fewer than 10% of monitored values (excluding crossover periods) as major protocol violations
1.2. We will consider the number of crossovers to be acceptable if fewer than 10% of patients cross over to the alternate ventilator, when not allowed by protocol
1.3. We will consider patient accrual to be adequate if we recruit 60 patients from 10 sites over one-year
Secondary outcome measures
No secondary outcome measures
