perfusion pressure
The driving pressure that maintains blood flow through tissue capillary beds.
Full Definition
Perfusion pressure represents the pressure gradient between arterial inflow and venous outflow that drives blood through the microcirculation. In vascular medicine, it is critical for assessing tissue viability and healing potential. Reduced perfusion pressure, often due to arterial disease, can lead to tissue ischemia and impaired wound healing. Measurements such as toe pressures and transcutaneous oxygen levels help quantify perfusion adequacy.
In Context
- "Adequate perfusion pressure is essential for ulcer healing in diabetic patients." — Wound care assessment
- "The perfusion pressure gradient determines the success of limb salvage procedures." — Surgical consultation note
