Purpose
This phase II multi-centered, randomized controlled trial of mechanical ventilation directed by esophageal pressure measurement will test the primary hypothesis that using a strategy of maintaining a minimal but positive transpulmonary pressure (PTP = airway pressure minus pleural pressure) throughout the ventilatory cycle will lead to an improvement in patient survival.

Primary Outcome Measures:
- A composite outcome of mortality and time off the ventilator at 28-days. [ Time Frame: Day 28 ] [ Designated as safety issue: No ]The trial will utilize a primary composite endpoint that incorporates death and days off the ventilator at 28 days in such a manner that death constitutes a more serious outcome. Every subject in the treatment group is compared to every subject in the control group and assigned one number resulting from each comparison. Since mortality outcome is clinically more important, mortality takes precedence over days off the ventilator. These scores are summed up to obtain a cumulative score for each subject. The cumulative scores are added up for each treatment group to form a test statistic by the Mann-Whitney technique.
Secondary Outcome Measures:
- Ventilator free days to day 28 [ Time Frame: Day 28 ] [ Designated as safety issue: No ]
- mortality [ Time Frame: Day 60 ] [ Designated as safety issue: Yes ]Hospital and ICU mortality to days 28 and 60
- lengths of stay [ Time Frame: Day 60 ] [ Designated as safety issue: No ]Hospital and ICU lengths of stay to days 28 and 60
- biomarkers of lung injury [ Time Frame: Day 7 ] [ Designated as safety issue: No ]Plasma biomarkers of lung injury on enrollment and days 3 and 7 after enrollment
- Survival [ Time Frame: 1 year ] [ Designated as safety issue: No ]
- Quality of life [ Time Frame: 1 year ] [ Designated as safety issue: No ]Will assess via questionnaires (SF-12, Barthel Index, VES-13) done by phone at 12 months
- Need for rescue therapy [ Time Frame: Day 28 ] [ Designated as safety issue: Yes ]Rescue measures will be chosen according to the practice at the clinical site, and may include repeated recruitment maneuvers, prone positioning, nitric oxide, epoprostenol sodium, airway pressure release ventilation, high frequency ventilation, or ECMO.

Experimental: EPVent
The overall goals for the "EPVent" group (esophageal-pressure guided mechanical ventilation) are to employ an open-lung strategy that includes low tidal volumes and maintenance of a positive transpulmonary pressure at end-expiration [Ptpexp]. Fraction of inspired oxygen [FiO2] and transpulmonary pressure pressure during an expiratory hold will be changed to achieve values shown in one of the columns of a protocol-specified table to meet the oxygenation target.

Other: Esophageal-pressure guided mechanical ventilation

Active Comparator: Control
The overall goals for the Control group are similar to those for the EPVent group: to employ an open-lung strategy that includes low tidal volumes using an alternative high positive end-expiratory pressure [PEEP] strategy. The control group PEEP and tidal volume will be managed without reference to the esophageal pressure measurements. PEEP and FiO2 will be raised or lowered to achieve the oxygenation target level

Criteria
Inclusion Criteria:
Acute onset of ARDS as defined by the Berlin Consensus Conference definitions:
- Hypoxemic respiratory failure with PaO2 / FIO2 ratio < 200 mmHg
- b) Bilateral alveolar/interstitial infiltrates on chest x-ray, with opacities not present for more than 7 days
- Respiratory failure not fully explained by cardiac failure or fluid overload
- Intubation on controlled ventilation and receiving PEEP ≥ 5 cm H2O
- Age 16 years or older
- Duration of ARDS 36 hours or less from meeting final Berlin criterion.
Exclusion Criteria:
- Received mechanical ventilation more than 96 hours
- Recently treated or bleeding varices, esophageal stricture, hematemesis, esophageal trauma, recent esophageal surgery or other contraindication for nasogastric tube placement
- Severe coagulopathy (platelet count < 5000/microliter or INR > 3)
- History of lung or liver transplantation
- Elevated intracranial pressure or conditions where hypercapnia-induced elevations in intracranial pressure should be avoided
- Evidence of active air leak from the lung
- not committed to full support
- Participation in other intervention trials for ARDS or for sepsis within the past 30 days.
- Neuromuscular disease that impairs ability to ventilate spontaneously
- Severe chronic liver disease, defined as Child-Pugh Score of ≥12
- Treating clinician refusal, or unwillingness to commit to controlled ventilation for at least 24 hours
- Inability to get informed consent from the patient or surrogate.
- Use of rescue therapies for prior to enrollment (e.g. nitric oxide, ECMO, prone positioning, high frequency oscillation). This does not exclude cases where these therapies were used as the initial mode of ventilation
