What are the SIRS criteria?
|
A. Core temperature* of >38.3°C (>100.9°F), >38.5°C (>101.3°F) in children, or <36°C (<96.8°F).
B. Tachycardia (in the absence of an external stimulus, long-term use of drugs, painful stimuli; or otherwise unexplained persistent elevation over 30 min): a heart rate of >90 beats/min; or in children, a mean heart rate >2 SD above normal for age; or in children <1 y of age: bradycardia, defined as a mean heart rate <10th percentile for age. C. Mean respiratory rate >20 breaths/min or PaCO2 <32 mm Hg; or in children >2 SD above normal for age or mechanical ventilation for an acute process not related to underlying neuromuscular disease. D. Leukocyte count >12,000/mm3 or <4000/mm3, or >10% immature (band) forms, or in children elevated or depressed level for age (not secondary to chemotherapy-induced leukopenia). |

|
define sepsis
|
The systemic response to infection, manifested by the presence of two or more of the conditions listed above as criteria for SIRS
|
|
|
define severe sepsis
|
Sepsis plus one of the following: cardiovascular organ dysfunction or acute respiratory distress syndrome or dysfunction of two or more other organs
|
|
|
Define septic shock
|
A state of acute circulatory failure characterized by persistent arterial hypotension unexplained by other causes. Hypotension is defined as a systolic arterial pressure <90 mm Hg (in children, a pressure <2 SD below normal for age); a mean arterial pressure <60 mm Hg, or a reduction in systolic blood pressure of >40 mm Hg from baseline, despite adequate volume resuscitation, in the absence of other cause of hypotension.
