Title
(KO) 신호 천이 시간을 사용한 심혈관 상태 모니터링
Abstract
(KO)
심혈관 상태, 즉, 과역동성 순환, 혈관확장, 혈관수축, 또는 중심-대-말초 동맥압 탈동조화 상태를 모니터링하는 방법을 기술한다. 이러한 방법은 대상체의 심장 활성에 비례하거나 또는 상기 심장 활성과 함수 관계에 있는 중심 신호, 및 중심 신호와 관련이 있는 신호에 비례하거나 또는 상기 중심 신호와 관련이 있는 신호와 함수 관계에 있는 말초 신호를 측정하는 단계를 포함한다. 이어서, 중심 신호 및 말초 신호에 대해 동일한 심장 이벤트를 나타내는 특징들 사이의 시간차를 산출한다. 심혈관 상태는 그 시간차가 역치값보다 큰 경우 또는 작은 경우, 특정 기간에 걸쳐 나타나는 시간차가 역치값보다 큰 경우 또는 작은 경우, 또는 특정 기간에 대한 시간차에서의 유의한 통계학적 변화가 있는 경우에 제시된다. 이러한 방법은 대상체가 심혈관 상태를 경험하고 있음을 사용자에게 경고할 수 있고, 이를 통해 의사는 대상체에게 적절한 치료법을 제공할 수 있다.
