Low Perfusion™ pulse oximetry, introduced in 1995, has been shown in over 100 independent and objective studies to outperform other pulse oximetry technologies.[2] Masimo SET® has also been shown to help clinicians reduce severe...

상승하며 정점에 도달하는 시간이 지연되고 장골동맥 정점에 비해 활성도가 낮다. 이를 정략적으로 계산하여 관류지수(Perfusion index)로 표현하기도 한다. 즉 동맥곡선 이하면적(area under the arteria curve)와 신혈류곡선 이하면적과의 비율을 계산...
