Description
図1は、本発明の原理による圧力サポートシステム30の例示的な実施の形態を概略的に図示する。圧力サポートシステム30は、概して32で示される圧力生成システム及び患者回路34を含む。患者回路34は、管路36及び患者インタフェース装置38を含む。図示された実施の形態において、圧力生成システム32は、圧力発生器40及び圧力発生器の流出口に結合される圧力制御弁42を含む。破線31によって示されるハウジングは、圧力サポートシステムのコンポーネントの多くを含む。
本発明の原理による圧力サポートシステム30の動作が次に、図2を参照して説明される。図2は、本発明の単純化されたバージョンに従ってコントローラ50によって実現される圧力制御プロセスの概略図である。制御ステップ(ボックス)60において、制御ステップ60から出力される矢印62によって示されるように、コントローラ50は、治療設定値(TSP)を決定するか又は治療設定値(TSP)を与えられる。治療設定値は、コントローラが達成しようとしている呼吸治療療法のパラメータに対応する。例えばCPAPシステムにおいて、TSPはCPAP圧力である。二相性システムでは、TSPは実際には、IPAP及びEPAPレベルである2つのTSPである。言い換えると、療法設定値は、通常の療法セッションの間にコントローラが圧力サポートシステムに到達させようとする制御されたパラメータ又は複数のパラメータの値である。
a) 圧力。
b) 流動又はボリューム。
c) 時間。
d) 装置設定(CPAP、IPAP、EPAP、圧力サポート、予備呼吸速度、吸息の時間、加湿設定、ターゲット体積、ターゲット流動、ピークボリューム、ピーク流動、ピーク圧力、平均ボリューム、平均流動、平均圧力)。
e) 圧力サポートシステムと関連したハードウェア(例えば、患者回路タイプ、患者のインタフェースタイプ、加湿器タイプ、フィルタタイプ、センサタイプ、追加の酸素など)。
f) 環境状態(高度、湿度、温度など)。
g) 患者の状態(覚醒/睡眠状態、睡眠段階、気道開通性、呼吸ドライブ、患者の健康、酸素飽和(SaO2)レベル、活動レベルなど)。
h) 圧力生成システムの使用量(コンプライアンス)。
Claims (6)
