Which system shows initial signs of dysfunction in systemic Respiratory system
inflammatory response syndrome (SIRS) and multiple organ
dysfunction syndrome (MODS)? The pulmonary vasculature is directly affected by inflammatory mediators. Hence the
initial signs of dysfunction in systemic inflammatory response syndrome (SIRS) and
Respiratory system multiple organ dysfunction syndrome (MODS) are seen in the respiratory system.
Cardiovascular system Cardiovascular changes are detected later when there is myocardial depression.
Gastrointestinal system Effects on the gastrointestinal system are seen when the motility gets decreased.
Central nervous system Neurologic dysfunctions are seen when the patient's mental status begins to show
signs of change.

Confusion, agitation, and lethargy and finally the dysfunction results in hepatic encephalopathy. The patient's dyspnea is
caused by changes in the respiratory system by inflammatory mediators.
