Abstract: A stand-alone continuous positive airways pressure, CPAP, apparatus having a face-mask and a connected electro-mechanical device to supply air to the face-mask is disclosed. The electro-mechanical device includes a pneumatic channel for flowing air to be delivered to the face mask and a control unit for managing the air pressure of the air inside the pneumatic channel. The CPAP apparatus includes a turbine fan, located in the electro-mechanical device housing, connected to the control unit for pressurizing atmospheric air. The pneumatic channel includes an inlet portion located upstream of the turbine fan to receive atmospheric air, and an outlet portion located downstream of the turbine fan to deliver the pressurized air to the face-mask through an outlet opening. The pneumatic channel also longitudinally extends from the inlet portion to the outlet portion.
