Problems solved by technology
Thus, adjustment of the fit or stability of the nasal assembly directly affects the seal, which can adversely affect patient comfort.
Similar to Trimble, adjustment of the fit or stability of the nasal assembly directly affects the seal, which can adversely affect patient comfort.
A common problem with known nasal assemblies, such as those discussed above, is patient comfort.
For example, the prongs tend to irritate the patient's nose due to the tension applied by the headgear assembly that pulls the rigid shell and prongs towards the patient's nose.
Another problem is achievement of a sealing fit with

Abstract
A nasal assembly for delivering breathable gas to a patient includes a frame having lateral connector, a cushion with a pair of nozzles, and a clip to secure the cushion to the frame. The frame includes a vent channel and a plurality of vent holes. The frame/cushion includes structure (lugs/cut outs) to prevent the assembly of an unvented frame with an unvented cushion, for safety purposes. The frame includes cored portions that interface with corner lugs provided on the cushion. A patient interface includes a frame, a cushion (nasal mask, nasal-oro mask, nozzles, etc.) and a vent assembly including a pattern of vent holes including at least two rows.
