Abstract: A portable continuous positive airway pressure (CPAP) device is adapted for delivering gas under pressure to a patient. The CPAP device comprises a portable housing assembly, a motor blower unit disposable within the portable housing assembly, a user interface configured to be engaged to the patient, and a patient hose extending between the user interface and the motor blower unit. The portable housing assembly may be comprised or configured as a wearable frontpack assembly which is configured to be worn against the patient's chest. The frontpack assembly may include a pair of shoulder straps configured to extend over the patient's shoulders and under the patient's arms to secure the CPAP device to the patient. The motor blower unit may be remotely disposed from the portable housing assembly such as on a bedside assembly or on a tabletop stand.
