Although many new areas of research are directed at the regulatory aspects of the metabolic response, the prognosis of MOF remains poor. Critical care nurses, challenged to provide a supportive environment during this life-threatening syndrome, must understand its onset, clinical patterns, and prolonged support required by patients. Such knowledge will enable critical care nurses to detect subtle changes while monitoring clinical status, and facilitate timely interventions in order to decrease the morbidity and mortality associated with MOF.
