Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a severe lung condition that causes respiratory failure. Individuals with ALI/ARDS often require the use of a respirator or artificial breathing machine, known as a mechanical ventilator, while in an intensive care unit (ICU). Research has shown that lung protective ventilation (LPV), a type of mechanical ventilation technique, is an effective way to reduce the number of deaths due to ALI/ARDS. This study will evaluate the effectiveness of a Web-based educational program that aims to educate ICU clinicians about the use of LPV in patients with ALI/ARDS.
