and a primary headgear comprising a pair of arms extending in opposite directions from a central region, the central region being configured to engage and support the patient interface on the patient's face, wherein the central region of the primary headgear comprises an aperture configured to receive a portion of the patient interface. ### Claim 2 (depends on 1) The patient interface system of claim 1, wherein each of the pair of arms is configured to engage the patient's nose. ### Claim 3 (depends on 1) The patient interface system of claim 1, further comprising a securing pad configured to be positioned across the bridge of the patient's nose. ### Claim 4 (depends on 3) The patient interface system of claim 3, wherein each of the pair of arms comprises a securing portion adjacent an end of the respective arm that is distal to the central region, the securing portions being removably attachable to the securing pad. ### Claim 5 (depends on 1) The patient interface system of claim 1, further comprising a supplemental headgear attachable to the primary headgear and configured to wrap around the patient's head. ### Claim 6 (depends on 1) The patient interface system of claim 1, wherein the sealing portion of the patient interface comprises a pair of nozzles. ### Claim 7 (depends on 1) The patient interface system of claim 1, wherein the sealing portion of the patient interface comprises a single nasal seal. ### Claim 8 (depends on 1) The patient interface system of claim 1, wherein the patient interface is configured to be supported from the primary headgear at the aperture. ### Claim 9 (depends on 1) The patient interface system of claim 1, further comprising: a securing pad configured to be positioned across the bridge of the patient's nose; and a supplemental headgear attachable to the primary headgear and configured to wrap around the patient's head, wherein each of the pair of arms is configured to engage the patient's nose, wherein each of the pair of arms comprises a securing portion adjacent an end of the respective arm that is distal to the central region, the securing portions being removably attachable to the securing pad, wherein the sealing portion of the patient interface comprises a pair of nozzles or a single nasal seal, and wherein the patient interface is configured to be supported from the primary headgear at the aperture. ### Claim 10 A patient interface system configured to deliver pressurized breathable gas to a patient's airways, the patient interface system comprising: a suspension system configured to wrap around the patient's nose and comprising a pair of laterally opposed arms extending from a central region; and a patient interface configured to be suspended from the suspension system and comprising a sealing portion configured to sealingly engage the patient's nose when the patient interface system is mounted on the patient's face, wherein the central region of the suspension system comprises an aperture configured to receive a portion of the patient interface to anchor the patient interface to the suspension system. ### Claim 11 (depends on 10) The patient interface system of claim 10, further comprising a securing pad configured to be positioned across the bridge of the patient's nose. ### Claim 12 (depends on 11) The patient interface system of claim 11, wherein each of the pair of laterally opposed arms comprises a securing portion adjacent an end of the respective laterally opposed arm that is distal to the central region, the securing portions being removably attachable to the securing pad. ### Claim 13 (depends on 10) The patient interface system of claim 10, wherein the central region of the suspension system is shaped to avoid the patient's septum and/or upper lip in use. ### Claim 14 (depends on 10) The patient interface system of claim 10, further comprising a supplemental headgear attachable to the suspension system and configured to wrap around the patient's head. ### Claim 15 (depends on 14) The patient interface system of claim 14, wherein the suspension system comprises connectors between the central region and the laterally opposed arms, the connectors being configured to connect to the supplemental headgear. ### Claim 16 (depends on 10) The patient interface system of claim 10, wherein the sealing portion of the patient interface comprises a pair of nozzles. ### Claim 17 (depends on 10) The patient interface system of claim 10, wherein the sealing portion of the patient interface comprises a single nasal seal. ### Claim 18 (depends on 10) The patient interface system of claim 10, further comprising a securing pad configured to be positioned across the bridge of the patient's nose; and a supplemental headgear attachable to the suspension system and configured to wrap around the patient's head, wherein each of the pair of laterally opposed arms comprises a securing portion adjacent an end of the respective laterally opposed arm that is distal to the central region, the securing portions being removably attachable to the securing pad, wherein the central region of the suspension system is shaped to avoid the patient's septum and/or upper lip in use, wherein the suspension system comprises connectors between the central region and the laterally opposed arms, the connectors being configured to connect to the supplemental headgear, and wherein the sealing portion of the patient interface comprises a pair of nozzles or a single nasal seal.
