Brief Summary

Based on recent two-center results (Eur Respir J. 2011 Sep 1. \[Epub ahead of print\] PMID: 21885390) we hypothesized that intermittent High-frequency oscillation (HFO) combined with Recruitment Maneuvers (RMs) may beneficially affect the pathophysiology and survival of patients with moderate-to-severe Acute Respiratory Distress Syndrome (ARDS). Design: Randomized Controlled Trial. Intervention: Briefly, the HFO-RMs strategy of the intervention (HFO-RMs) group will comprise RMs (3/day) and an initial HFO session of 96 hours (HFO session can be interrupted before the 96-hour time point only if PaO2/FiO2 rises to \>200 mmHg for \>12 hours), followed by return to lung protective conventional mechanical ventilation (CMV) according to pre-specified oxygenation criteria. Within days 1-10 postrandomization, patients will be returned to HFO upon recurrence of their moderate-to-severe oxygenation disturbance. Patients of the control (CMV) group will receive lung protective CMV.

Study Arms (2)

CMV Arm

ACTIVE COMPARATOR

Patients with moderate-to-severe Acute Respiratory Distress Syndrome treated solely with lung protective, low volume high positive end-expiratory pressure conventional mechanical ventilation (CMV) and recruitment maneuvers, as specified in detail in the Detailed Description section.

Device: Lung protective CMV

HFO-RMs Arm

EXPERIMENTAL

Patients with moderte-to-severe Acute Respiratory Distress Syndrome treated initially with a 96-hour-lasting session (session duration modifiable according to oxygenation criteria) of High-frequency oscillation (HFO)-Recruitment Maneuvers (RMs), and then with lung protective CMV interspersed to additional HFO-RMs sessions (if required according to study protocol). The protocolized use of HFO-RMs may extend until day 10 post-randomization, according to pre-specified oxygenation criteria. Full details are provided in the Detailed Description Section.

Device: HFO-RMs

Interventions
