perfusion pressure

the gradient between arterial blood pressure and venous pressure in a comparable location in the vascular tree.

pulmonary perfusion

blood flow through the pulmonary capillaries.

renal perfusion

the rate of perfusion in the kidney is much higher than in any other organ. The rate of formation of urine depends to a large extent on the perfusion rate.

perfusion scan

using pulmonary scintigraphy, radionucleotide agents injected into a peripheral vein can be detected where it is trapped in the pulmonary capillary bed. Used to assess pulmonary blood flow.

perfusion technique

maintenance of blood circulation to tissues during cardiopulmonary bypass.

perfusion:ventilation ratio

see ventilation: perfusion ratio.

perfusion Bathing an organ or tissue with a fluid. See Arterial perfusion, Hyperthermic perfusion, Isolated hepatic perfusion, Limb perfusion, Myocardial perfusion Oncology A technique used for a melanoma of an arm or leg; circulation to and from the limb is stopped with a tourniquet; chemotherapy is put directly into the circulation to ↑ regional drug dose Transplantation The intravascular irrigation of an isolated organ with blood, plasma or physiologic substance, to either studying its metabolism or physiology under 'normal' conditions or for maintaining the organ as 'fresh' as possible, while transporting donated organs to recipients.
