In evaluating this complex field, it is critical that our view does not become colored by a single study or effectiveness in a particular disease state. Whether this is because of inappropriate study design, the complex nature and spectrum of ARDS, inefficacy of NO, inappropriate dosing, or counterbalancing toxic effects of NO is unknown.
