Claims (10)
- ヒトにおける換気を行い、胸部圧迫の効率を高めるためのシステムであって、
前記ヒトの呼吸口内に挿入されるように構成され、前記ヒトの身体通路内に配置するための作業部を有する換気装置を備え、
前記換気装置は、前記作業部に露出した圧力ルーメンを有し、前記圧力ルーメンは、前記圧力ルーメンを用いて前記身体通路内の圧力変化を検知するように構成されたセンサーと流体連通し、
前記換気装置は、前記ヒトを換気するために前記作業部を通して空気のボーラスを供給するように構成された制御システムを有し、
前記制御システムは、前記胸部圧迫の結果生じる前記身体通路内の前記圧力変化を検知すると、前記空気のボーラスの送達タイミングを変更し、かつ、血流を増加させるために体積を増加させた空気のボーラスを送達して前記胸部圧迫後に前記ヒトの胸腔をさらに再膨張させるように構成され、
前記システムは、予め定められた閾値を下回る圧力変化の検出したときに、設定された速度で前記ヒトを換気する、システム。 - 前記制御システムは、前記身体通路内の前記圧力変化をフィードバックするようにさらに構成される、請求項1に記載のシステム。
- 前記制御システムは、前記胸腔内の空気の体積の変化を測定することにより、前記胸部圧迫の質に基づいて前記フィードバックを提供するように構成される、請求項2に記載のシステム。
- 前記フィードバックは、胸部圧迫の所望の時間を識別するために示す指示信号からなる、請求項2に記載のシステム。
