Cardiac arrhythmias, including tachycardias and bradycardias, can be observed as a result of autonomic nervous system involvement. Tachypnea may be a sign of ongoing dyspnea and progressive respiratory failure.

Blood pressure lability is another common feature, with alterations between hypertension and hypotension. Temperature may be elevated or low.

Respiratory examination may be remarkable for poor inspiratory effort or diminished breath sounds. On abdominal examination, paucity or absence of bowel sounds suggests paralytic ileus. Suprapubic tenderness or fullness may be suggestive of urinary retention.
