Abstract: A sizing gauge (4) is structured to be used with a patient (8) and is structured to enable an identification of a particular patient interface that is most appropriately sized for the patient. The sizing gauge includes a support portion (12) and a sizing portion (16). The sizing portion includes a first gauge element (36) and a plurality of second gauge elements (40A,40B,40C). The first gauge element is disposed on the support portion and is structured to be positioned at a first location on the patient's face. The plurality of second gauge elements are disposed on the support portion and are situated at locations spaced from the first gauge element. The distance between the first gauge element and each second gauge element is representative of a size in one direction (44) of each of at least some of the plurality of patient interfaces. At least one of the plurality of second gauge elements comprises a tactile feature.

Abstract: A patient interface device storage system includes a patient interface device structured to deliver a flow of breathing gas to a patient, the patient interface device including a mask, and a storage shell having an outer peripheral wall and a bottom wall which together define a cavity. The cavity is sized and configured to receive and hold at least a portion of the mask. The bottom wall includes a first attachment member structured to be selectively engaged with a second attachment member associated with a gas delivery device in a manner such that the storage shell and the patient interface device are coupled to and held by the second attachment member.

Abstract: A patient interface storage system (2) includes a patient interface device (4) structured to deliver a flow of breathing gas to a patient, the patient interface device including a mask, and a storage shell (6) having an outer peripheral wall and a bottom wall which together define a cavity. The cavity is sized and configured to receive and hold at least a portion of the mask. The bottom wall includes a first attachment member structured to be selectively engaged with a second attachment member associated with a gas delivery device in a manner such that the storage shell and the patient interface device are coupled to and held by the second attachment member.

Abstract: A device and method of providing positive pressure support that employs a patient interface device (2, 102) having a mask (6, 106) and an adjustment arm (26, 126) coupled to the mask. The adjustment arm includes an extension member (28) extending from the mask. The mask engages the face of the patient and the adjustment arm is spaced from and not in engagement with the head of the patient. The method includes adjusting the pressure applied to the patient by the mask by adjusting a strapping force applied to the patient interface device without causing the adjustment arm to engage the head of the patient, as well as providing a flow of gas to the patient through the mask without causing the adjustment arm to engage the head of the patient.
