سلام ، کشت پرفیوژن چیست؟اگر ممکنه کمی راهنماییم کنید .تشکر
سلام دوست عزيز ،پرفيوژن در فيزيولوژي فرايند انتقال غذا از رگ هاي خوني بهمويرگ هاي خوني در بستر بافته از تست پرفيوژن براي ارزيابي بيمار توسط پزشكان استفاده ميشه .
In
physiology,
perfusion is the process of nutritive delivery of
arterial blood to a
capillary bed in the
biological tissue. The word is derived from the French verb "perfuser" meaning to "pour over or through."
Tests of adequate perfusion are a part of the patient assessment process performed by
medical or emergency personnel. The most common methods include evaluating skin color, temperature, condition and capillary refill.
Overperfusion and underperfusion
The terms "overperfusion" and "underperfusion" are measured relative to the average level of perfusion across all tissues in an individual body, and the terms should not be confused with
hypoperfusion and "hyperperfusion", which measure the perfusion level relative to the tissue's current need.
Tissues like the
skin are considered overperfused and receive more blood than would be expected to meet the metabolic needs of the tissue. In the case of the skin, extra blood flow is used for
thermoregulation. In addition to delivering
oxygen, the blood helps
dissipate heat by redirecting warm blood close to the surface where it can cool the body through
sweating and
thermal radiation.
