1. A portable and head-wearable positive airway pressure (PAP) system, comprising:
a headgear wearable on a head of a patient;
a patient interface mask mounted to the headgear and having a cushion to engage with a face of the patent when the headgear is worn by the patient; and
a head-wearable blower supported by the headgear and configured to deliver pressurized air to a breathing cavity of the patient interface mask when the headgear is worn by the patient, wherein the head-wearable blower houses: an electric motor comprising a rotor assembly that includes a rotatable magnet mounted together with a rotatable central shaft, at least one impeller that is driven by the rotatable central shaft of the electric motor, and an elastomeric component positioned adjacent to the at least one impeller to reduce vibration within the head-wearable blower.
