Consensus clinical definition of ALI or ARDS:
* Partial pressure of oxygen in arterial blood to the fraction of inspired oxygen (PaO2 / FiO2) ratio ≤ 200 (ARDS) or ≤ 300 (ALI), and;
* Bilateral infiltrates on chest x-ray, and;
* No clinical evidence of congestive heart failure, and;
* Pulmonary artery occlusion pressure (PAOP) ≤ 18 mm Hg, if a pulmonary arterial catheter is present
Serum total protein concentration \< 6.0 g/dL.
Endotracheal intubation and mechanical ventilation ≥ 24 hours.
You may not be if

* Ongoing fluid resuscitation defined as \> 2 liters of crystalloid boluses or \> 4 units of blood products transfused in the prior 24-hour period.
* Vasopressor support exceeding any of the following:
Dopamine or dobutamine \> 5 mcg/kg/min, or in combination at any dose; or
Any other vasoactive agent (i.e. epinephrine, norepinephrine, phenylephrine)
