<unk>  <unk>  is a form of positive airway<unk>  (PAP) ventilation in which a constant level of<unk>  greater than atmospheric<unk>  is<unk> ly applied to the upper respiratory tract of a person. The application of positive<unk>  may be intended to prevent upper airway collapse, as occurs in obstructive sleep apnea, or to reduce the work of breathing in conditions such as acute decompensated heart failure.<unk>  therapy is highly effective for managing obstructive sleep apnea. Compliance and acceptance of use of<unk>  therapy can be a limiting factor, with 8% of people stopping use after the first night and 50% within the first year.
