20140090648 | METHOD AND APPARATUS FOR TREATING APNEA/HYPOPNEA - Methods and/or apparatuses for treating sleep-disordered breathing (SDB) are provided. In particular, systems and/or methods are provided which may temporarily boost the pressure of a supply of breathable gas provided by an AutoSet device for the treatment of hypopnea. In certain example embodiments, a supply of breathable is provided to patients to treat apneas and/or hypopneas. The presence and/or absence of apneas and/or hypopneas are detected (e.g. by monitoring the Apnea-Hypopnea Index). When hypopnea events are detected, the pressure of the supply of breathable gas temporarily is increased above the Pcrit and/or CPAP levels, at least during patient inspiration. When the hypopnea events are normalized, the pressure is reduced. In certain example embodiments, the pressure will not be increased when a non-hypopnea event is detected at the same time as a hypopnea event. | 04-03-2014 |
