관류

1935년 경의 린드버그 관류 펌프. 자연 관류를 시뮬레이트하기 위한 초기 기구.

관류(灌流, perfusion)는 순환계통이나 림프계통을 통해 유체를 장기나 신체조직으로 흘려보내는 일이며[1] 보통 혈액을 조직내 모세혈관계에 전달하는 것을 가리킨다. 관류는 혈액이 조직에 전달되는 속도,[2] 단위조직 질량 당 시간에 따른 혈액량으로 측정된다. SI 단위는 m3/(s·kg)이지만 인간의 장기의 관류에 사용할 때에는 보통 ml/min/g 단위로 보고된다.[3] 이 용어의 영단어 퍼퓨전(perfusion)은 "흘려 보내다"를 의미하는 프랑스어 동사 perfuser에서 비롯된 것이다.[4] 모든 동물 조직들은 건강과 삶을 위해 적절한 혈액 공급이 필요하다. 혈액 공급이 잘 되지 않는 허혈이 발생하면 관상동맥질환, 말초동맥질환 등 심혈관계 질환에서 보이는 건강 문제를 일으킬 수 있다.
