2.2.4 患者インタフェース
2.2.5 呼吸圧力治療(RPT)装置
加湿なしに空気の流れを送出すると、気道が乾燥することがある。必要な場合、例えば患者が睡眠中または休息中(例えば病院にて)、周囲温度に関連して絶対湿度および/または空気の流れの温度を上げるのに、医療加湿器すなわち呼吸治療装置用加湿器を使用できる。その結果、医療加湿器はベッドのそばに置くので小さくてよく、患者の周囲を加湿および/または加熱することなく、患者に送る空気の流れをただ加湿および/または加熱するように構成されてよい。室内設置のシステム(例えば、サウナ、空調、蒸発冷却器)も患者が呼吸する空気の加湿に使用できるが、部屋全体を加湿および/または加熱することになり、居住者に不快をもたらす。
