A cushion member (12, 12′, 12″) for a patient interface device (4) that includes a main body portion (34) including a plurality of chambers (48) and a self-sealing cap portion (36) coupled to the main body portion. The cap portion covers each of the chambers and forms a plurality of membrane members (52), with each membrane member being positioned over and sealing a respective one of the chambers. The cap portion is made of a self-sealing material such that that each of the membrane members is structured to self-seal responsive to having a needle inserted through and pulled out of the membrane member. Also, an apparatus and a method for selectively adjusting the internal pressure of the chambers of such a cushion.
