- 11.前記振幅(An)と弱い呼吸低下の閾値(S1)および強い呼吸低下の閾 値(S2)とを比較する手段を備えており、該振幅が、該弱い呼吸低下の閾値( S1)に相対して該強い呼吸低下の閾値(S2)を越えている場合には、前記自 動調節手段は比較的大きな第1の増加調節(x)によって加えられる圧力を増加 させ、該振幅が該2つの閾値(S1、S2)の間にある場合には、比較的小さな 第2の増加調節(x)によって加えられる圧力を増加させる請求項1または4に 記載の装置。
- 12.呼吸低下を検出した後に前記閾値を低下させる手段(24)を有する請求 項8に記載の装置。
- 13.前記振幅(An)が呼吸低下を示す値を保持している場合に、前記自動調 節手段が、連続的に増加する調節(X)によって圧力(Pc)を増加させるよう に構成された請求項1または4に記載の装置。
- 14.所定の時間間隔に許される圧力増加(MAP)を制限する手段(34、3 7)を備えている。請求項13に記載の装置。
