Answer
Most patients who are in a septic state experience respiratory distress secondary to severe sepsis or as a manifestation of septic shock. Pulmonary dysfunction of sepsis (ie, acute respiratory distress syndrome [ARDS]) also may occur. These patients need intubation and mechanical ventilation for optimum respiratory support.
