Further study details as provided by McMaster University:

Primary Outcome Measures:

Hospital Mortality

Secondary Outcome Measures:

Mortality attributed to respiratory failure
Duration of respiratory failure and duration of mechanical failure
Evaluation of respiratory function during mechanical ventilation
Incidence of barotraumas
Non-respiratory organ dysfunction


Estimated Enrollment:	980
Study Start Date:	August 2000
Study Completion Date:	March 2006

Detailed Description:

To compare an innovative Lung Open Ventilation strategy with a proven low tidal volume strategy, hypothesizing that the Lung Open Ventilation strategy may reduce mortality, other organ dysfunction, and the duration of mechanical ventilation, intensive care, and hospital stay.

Eligibility


Ages Eligible for Study:	18 Years and older (Adult, Senior)

Pregnancy
Very unlikely to survive and lack of commitment to life support Underlying irreversible condition with 6 month mortality >= 50%
Greater than 48 hours elapsed since first eligible
Current participation in competing trial
Lack of physician, patient or proxy consent
