A system/method for reducing or eliminating application of continuous, repeated, and/or excessive pressure at the contact footprints of a patient interface device and headgear assembly. For example, a patient interface with a plurality of cushions, each producing a different contact footprint when worn by the patient is employed. As another example, a plurality of patient interface devices, each having a cushion that produces a different contact footprint when worn by the patient, are employed. As another example, a patient interface device having a cushion, the configuration/shape of which can be altered such that the contact footprint which it produces is also changed, is employed. The contact footprint to which the patient is exposed is altered after a predetermined time period.

1. A method for providing a respiratory therapy regimen to a patient, comprising: fitting the patient with a patient interface device, wherein the patient interface device has at least a first cushion, a second cushion and a third cushion associated therewith, wherein the first cushion is structured
1. A method for providing a respiratory therapy regimen to a patient, comprising: fitting the patient with a patient interface device, wherein the patient interface device has at least a first cushion, a second cushion and a third cushion associated therewith, wherein the first cushion is structured to produce a first contact footprint relative to the face of the patient by contacting a first portion of the face of the patient, the first contact footprint having a generally triangular shape, wherein the second cushion is structured to produce a second contact footprint relative to the face of the patient by contacting a second portion of the face of the patient, the second contact footprint having a generally elliptical shape, and wherein the third cushion is structured to produce a third contact footprint relative to the face of the patient by contacting a third portion of the face of the patient, the third contact footprint having a third shape, the third shape being different from the generally triangular shape and the generally elliptical, and wherein the patient interface device is selectively configurable to include any one of the first, second and third cushions;configuring and using the patient interface device according to a rotation, wherein in the rotation the patient interface device is configured to include the first cushion and a flow of breathing gas is delivered to the airway of the patient via the patient interface device during a first predetermined period, the patient interface device is configured to include the second cushion and a flow of breathing gas is delivered to the airway of the patient via the patient interface device during a second predetermined period, and the patient interface device is configured to include the third cushion and a flow of breathing gas is delivered to the airway of the patient via the patient interface device during a third predetermined period, wherein the first cushion includes a first visual marking indicating the first predetermined period, the second cushion includes a second visual marking indicating the second predetermined period, and the third cushion includes a third visual marking indicating the third predetermined period; andafter the configuring and using the patient interface device according to the rotation is completed, re-configuring and re-using the patient interface device one or more additional times according to the rotation to deliver a flow of breathing gas to the airway of the patient such that a location on the patient's face wherein pressure is applied by the patient interface device is continuously changing during the respiratory therapy regimen. 2. The method of claim 1, wherein the first cushion, the second cushion and the third cushion comprises one of a mask cushion, a forehead support cushion, a chin support cushion, and a cheek support cushion. 3. The method of claim 1, wherein the patient interface device comprises one of a nasal mask, a full-face mask, and a total face mask. 4. The method of claim 1, wherein the patient interface device has at least a fourth cushion, a fifth cushion, a sixth cushion and a seventh cushion associated therewith, wherein during the rotation the patient interface device is configured to include each of the fourth, fifth, sixth and seventh cushions. 5. The method of claim 4, wherein each of the first, second, third, fourth, fifth, sixth and seventh cushion has a day of the week associated therewith, wherein the first visual marking indicates the day of the week associated with the first cushion, wherein the second visual marking indicates the day of the week associated with the second cushion, wherein the third visual marking indicates the day of the week associated with the third cushion, and wherein the fourth, fifth, sixth and seventh cushions each includes a visual marking indicating that day of the week associated therewith. 6. The method of claim 1, wherein the first, second and third predetermined periods are each a day. 7. A method for providing a respiratory therapy regimen to a patient, comprising: fitting the patient with at least first, second and third patient interface devices, wherein the first patient interface device has a first cushion, the second patient interface device has a second cushion and the third patient interface device has a third cushion, wherein the first cushion is structured to produce a first contact footprint relative to the face of the patient by contacting a first portion of the face of the patient, the first contact footprint having a generally triangular shape, wherein the second cushion is structured to produce a second contact footprint relative to the face of the patient by contacting a second portion of the face of the patient, the second contact footprint having a generally elliptical shape, and wherein the third cushion is structured to produce a third contact footprint relative to the face of the patient by contacting a third portion of the face of the patient, the third contact footprint having a third shape different from the generally triangular shape and the generally elliptical shape;using the first, second and third patient interface devices according to a rotation, wherein in the rotation the first patient interface device is used to deliver a flow of breathing gas to the airway of the patient during a first predetermined period, the second patient interface device is used to deliver a flow of breathing gas to the airway of the patient during a second predetermined period, and the third patient interface device is used to deliver a flow of breathing gas to the airway of the patient during a third predetermined period, wherein the first patient interface device includes a first visual marking indicating the first predetermined period, the second patient interface device includes a second visual marking indicating the second predetermined period, and the third patient interface device includes a third visual marking indicating the third predetermined period; andafter the using the first, second and third patient interface devices according to the rotation is completed, re-using the first, second and third patient interface devices according to the rotation one or more additional times to deliver a flow of breathing gas to the airway of the patient such that a location on the patient's face wherein pressure is applied is continuously changing during the respiratory therapy regimen. 8. The method of claim 7, wherein the first, second a third cushions each comprise one of a mask cushion, a forehead support cushion, a chin support cushion, and a cheek support cushion. 9. The method of claim 7, wherein the first, second a third patient interface devices each comprise one of a nasal mask, a full-face mask, and a total face mask. 10. The method of claim 7, wherein the first, second and third predetermined periods are each a day.
