1. A cushion pad for a ventilator mask arranged to form a seal with a user'"'"'s face so as to provide pressurized gas to the user, the cushion pad comprising:
- a first surface adapted to contact the user'"'"'s face when the cushion pad is positioned on the user'"'"'s face;
a second surface opposite the first surface; and
an edge surface extending from the first surface to the second surface around a perimeter of the cushion pad, whereincentral portions of the first and second surfaces together form a central region of the cushion pad, the central region being adapted to extend along a central ridge of the user'"'"'s nose to at least the user'"'"'s nose bridge when the cushion pad is positioned on the user'"'"'s nose,lateral portions of the first and second surfaces form a pair of side regions of the cushion pad that extend in opposite directions laterally from the central region and are adapted to extend laterally from the user'"'"'s nose to an area beyond the user'"'"'s nose when the cushion pad is positioned on the user'"'"'s nose,the cushion pad is adapted to assist the seal in avoiding undue leakage of gas,the cushion pad is separate from the ventilator mask,a thickness of the central region tapers at a first slope from an upper portion to a lower portion of the central region so that the thickness at the upper portion is greater than the thickness at the lower portion, anda portion of the edge surface in the lower portion of the central region tapers from the second surface to the first surface at a second slope that is different from the first slope.

Abstract
The present invention is a gel cushion that is placed on a user'"'"'s nose bridge before putting on a ventilator mask. The gel cushion is composed of a tacky gel material, such as a viscoelastic polymer gel. The gel cushion is wider than the edges of the ventilator mask and remains in place even if the mask is repositioned. The gel cushion adapts to the user'"'"'s face in the area on and around the nose bridge to cushion and seal the ventilator mask in that area.

20. A cushion pad for a ventilator mask arranged to form a seal with a user'"'"'s face so as to provide pressurized gas to the user, the cushion pad comprising:
-
a first surface adapted to contact the user'"'"'s face when the cushion pad is positioned on the user'"'"'s face; a second surface opposite the first surface; and an edge around a perimeter of the cushion pad, the edge connecting the first surface to the second surface, wherein central portions of the first and second surfaces together form a central lobe adapted to extend along a central ridge of the user'"'"'s nose to at least the user'"'"'s nose bridge when the cushion pad is positioned on the user'"'"'s nose, lateral portions of the first and second surfaces form a pair of side lobes that extend laterally in opposite directions from the central lobe and are adapted to extend laterally from the user'"'"'s nose to an area beyond the user'"'"'s nose when the cushion pad is positioned on the user'"'"'s nose, the cushion pad is adapted to assist the seal in avoiding undue leakage of gas, the cushion is substantially T-shaped, the cushion pad is separate from the ventilator mask, a thickness of the cushion pad tapers at a first slope from an upper end of the cushion pad to a lower end of the cushion pad so that the thickness of the cushion pad at the upper end of the cushion pad is greater than the thickness of the cushion pad at the lower end of the cushion pad, and a portion of the edge at the lower end of the cushion pad tapers from the second surface to the first surface at a second slope that is different from the first slope. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 42, 43)

28. A cushion kit for a ventilator mask arranged to form a seal with a user'"'"'s face so as to provide pressurized gas to the user, in use, the cushion kit comprising:
-
a first pad separate from the ventilator mask and having a substantially T-shape with a central lobe and two side lobes, the central lobe being adapted to contact the user'"'"'s face and extend upward from a central ridge of the user'"'"'s nose to at least the user'"'"'s nose bridge and the side lobes being adapted to contact the user'"'"'s face and laterally extend from the user'"'"'s nose to an area beyond the patient'"'"'s nose when the first pad is positioned on the user'"'"'s nose; a second pad separate from the ventilator mask; and a sealable container containing both pads, wherein at least the first pad has a first surface adapted to contact the user'"'"'s face when the respective pad is positioned on the user'"'"'s face, a second surface opposite the first surface and a side surface connecting a side edge of the first surface to a side edge of the second surface, wherein the central lobe and the two side lobes of the first pad are formed by the first and second surfaces, wherein at least the first pad is adapted to assist the seal in avoiding undue leakage of gas, wherein a thickness of the first pad tapers at a first slope from an upper portion of the first pad to a lower portion of the first pad so that the thickness of the first pad at the upper portion of the first pad is greater than the thickness at the lower portion of the first pad, and a portion of the side surface at the lower portion of the first pad tapers at a second slope that is different from the first slope. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
