Acute Lung Injury

Hypoxemia is a major complication of acute lung injury, and it is often difficult to manage. Mediators such as nitric oxide and prostacyclin can improve oxygenation by increasing blood flow through ventilated areas. Prostaglandin E1 (PGE1) by continuous aerosol via a ventilator has also been shown to improve oxygenation [178]. At the present time the preponderance of the evidence indicates that transient changes in ventilation/perfusion relationships in the lung may improve oxygenation but do not change outcome. Such therapeutic manipulations should be done using appropriate experimental protocols.
