The clinical manifestations of sepsis may be flagrant or subtle. Awareness of the signs and symptoms of sepsis allows early recognition and prompt, appropriate management. The clinical presentation, relative frequency, and current pathophysiologic understanding of the manifestations of sepsis are reviewed. Special emphasis is placed on the cardiopulmonary manifestations, which are examined in a temporal sequence of preshock, early shock, and late shock states. While therapy for the underlying infection (such as antibiotics and drainage of abscesses) is often sufficient, therapy for the specific manifestations of sepsis may also be necessary. Guidelines for therapy for these manifestations of sepsis are given.
