characterization of the isolated, ventilated, and instrumented mouse lung perfused with pulsatile flow

절연은 환기 및기구 마우스 폐 준비는 안정과 타악기 폐동맥 혈관 압력 유량 관계가 폐 동맥 유량, 유량 파형,기도 압력과 왼쪽 심방 압력 이상의 독립적인 컨트롤과 함께 측정할 수 있습니다. 폐 혈관 저항이 멀티 포인트, 지속적인 압력 - 유량 곡선을 기준으로 계산되며 폐동맥 혈관 임피던스는 주파수의 범위에서 얻은 타악기 압력 유량 곡선에서 계산됩니다. 그것이 무시할 수없는 혈관 준수의 영향, 특히 폐동맥 순환에 포함되어 있기 때문에 현재 임상 인식으로, 임피던스는 저항보다 오른쪽 심실 afterload의 우수한 측정하기위한 한 방법입니다. 임피던스 세 중요한 통계 수치 - 제로 헤르츠 임피던스 Z 0, 특성 임피던스 Z C 및 전파 반사 R W의 색인 - 흐름에 사용할 수 말초 동맥 단면적, 근위 동맥 강성과 상류 - 하류 임피던스에 대한 통찰력을 제공합니다 불일치, 각각. 고립에서 얻어진 모든 결과는, 환기 및 perfused 폐 동정 신경계 톤, 볼륨 상태 및 마취의 효과에 독립적입니다. 우리는 폐의 emboli과 저항 및 임피던스에 대한 만성 hypoxia의 영향을 계량이 기술을 사용 있고, Z C의 압력 의존성을 사용 vasoactive 요원과 질병의 행동 사이트 (즉, 근위 대 말초) 구별할 수 있습니다. 또한, 이러한 기술은 마우스의 유전자 조작 종자의 폐에와 함께 사용하는 경우, 폐의 혈관 구조와 기능에 대한 분자 수준의 결함의 영향을 확인할 수 있습니다.
