Web19 Feb 2024 · The hallmark of shock is decreased perfusion to vital organs, resulting in multiorgan dysfunction and eventually death. Vasopressors increase vasoconstriction, which leads to increased systemic vascular resistance (SVR). Increasing the SVR leads to increased mean arterial pressure (MAP) and increased perfusion to organs.
