hemodynamic stability
Maintenance of adequate blood pressure and circulation to support organ perfusion.
Full Definition
Hemodynamic stability refers to the maintenance of adequate cardiovascular function with sufficient blood pressure, heart rate, and circulation to ensure adequate tissue perfusion and oxygenation. In acute care surgery, hemodynamic stability is a critical factor in determining the urgency and approach to surgical intervention. Stable patients may be candidates for non-operative management or delayed surgical intervention, while hemodynamically unstable patients typically require immediate operative intervention. Assessment includes vital signs, urine output, mental status, and laboratory markers of perfusion such as lactate levels and base deficit.
Usage
Usage note: Refers specifically to cardiovascular function, not overall clinical stability.
