hemodynamically unstable
Clinical condition characterized by inadequate circulation and tissue perfusion requiring immediate intervention.
Full Definition
Hemodynamically unstable refers to a clinical state where the cardiovascular system cannot maintain adequate circulation and tissue perfusion. This typically manifests as hypotension, tachycardia, altered mental status, decreased urine output, or signs of shock. In acute care surgery, hemodynamic instability often indicates ongoing bleeding, sepsis, or cardiovascular compromise requiring urgent intervention. Documentation should include specific vital signs and clinical indicators rather than using this term alone. The condition necessitates immediate resuscitation and may influence surgical timing and approach.
Usage
Usage note: Always specify supporting vital signs and clinical findings rather than using this term in isolation.
