Multiple organ failure.

Abstract

Diagnostic criteria for individual organ system failure are imprecise, a factor that adds a considerable amount of ambiguity to this area of clinical research. Nonetheless, multiple organ failure is a common sequela of ARDS and other catastrophic medical and surgical illnesses that continues to limit patient survival. The cumulative weight of investigative evidence currently supports the premise that concepts of acute respiratory failure must encompass the abnormal gas exchange in the systemic as well as the pulmonary microvasculature. In this context, we need not dispense with the term ARDS, as respiratory distress applies equally to the nonpulmonary organs as well as the lungs.
