Description
1.全ての測定について、テスト圧あるいは流れは10から20秒間安定しているように保持されなければならず、この期間中に平均の流れおよび圧力が記録される。
2.ステップ2および3の間の測定圧力は、非常に低い(0.2〜2cmH2O)。これは、異常に低い(CPAPについて)圧力でのファンの正確かつ安定した制御を必然的に伴う。この制御の理想的なモードは、一定の流れを届けることである。
3.ステップ5において、良好なリークに耐え得る密閉状態はブロック部材を用いて提供される。このステップの間、マスクはいかなるリークをもあらわにするように最高テスト圧で加圧される。これは、表示される流れを観察し、これが安定し、かつ最小であるようにブロック部材を調節することによってチェックすることができる。
4.特徴付けを確認するためにステップ8において行われ得る数多くの整合性のチェックがある。これらのいくつかは、
・テスト圧および流れの境界のチェック
・ホースの降下およびディフューザのリークのモデルに関するAおよびBの係数についての期待値のチェック
・AおよびBの係数のどちらも負でないことのチェック(圧力流れ曲線は、増加する勾配を有していなければならない)
である。
