Pad for a mask
A cushion pad for a mask worn by a patient, comprising a first side to contact skin of the patient, and a second side, opposite the first side, to contact or face the mask. The pad has a main body portion having a central portion shaped to cover a portion of the patient's nose extending from above the nose tip to the nasal bridge region without obstructing the patient's line of sight, and lateral side portions to extend downward and terminate along the sides of the nose or on the patient's cheeks. The main body is made of a breathable material, e.g., foam. The pad may include adhesive and/or an attached portion, e.g., a ring, to couple the pad to the patient and/or portion of the mask.
