WebShock is a state of organ hypoperfusion with resultant cellular dysfunction and death. Mechanisms may involve decreased circulating volume, decreased cardiac output, and vasodilation, sometimes with shunting of blood to bypass capillary exchange beds. Symptoms include altered mental status, tachycardia, hypotension, and oliguria. WebPatients with septic shock can be clinically identified by a vasopressor requirement to maintain a mean arterial pressure (MAP) ≥ 65mmHg and lactate > 2 mmol/L (>18mg/dL) in the absence of hypovolemia [1].
