Abstract

A vent arrangement is provided to a mask to discharge exhaled gas from the mask to atmosphere. The vent arrangement is structured to diffuse the exhaust vent flow to produce less air jetting, thereby increasing the comfort of the patient and their bed partner. The vent may include a first wall, a second wall defining an outer perimeter, and a plurality of gas washout vent holes positioned between the first wall and the second wall, the vent holes having an inner edge positioned within the outer perimeter of the second wall.

Description

[0001] Application cross-reference [0002] This application claims the benefits of the U.S. Provisional Application No. 61 / 433,422 filed on February 16, 2011 and the U.S. Provisional Application No. 61 / 628,300 filed on October 28, 2011. All of the said applications are incorporated by reference. The content is incorporated into this article. Technical field [0003] The present technology relates to mask vents for noninvasive positive pressure ventilation (NIPPV) and continuous positive airway pressure (CPAP) treatments for sleep disordered breathing (SDB) conditions such as obstructive sleep apnea (OSA). Background technique [0004] The treatment of sleep disordered breathing (SDB) such as obstructive sleep apnea (OSA) through continuous positive airway pressure (CPAP) flow generator system involves: via catheters and masks to humans or other mammals The patient's airway continuously delivers air (or other breathable gas) pressurized above atmospheric pressure. Typically, the m...
