Non-invasive ventilation system for the pre-hospital management of acute respiratory failure

Stand-alone continuous positive airways pressure, CPAP, apparatus to contrast respiratory failure of a patient comprising a face-mask to deliver contin­ uous pressured air to the patient's airways, and an electro-mechanical device having a housing directly and rigidly connectable to the face-mask to supply air to said face-mask at a controlled pressure value, the electro-mechanical device comprising a pneumatic channel for flowing air to be delivered to the face mask and a control unit for automatically managing the value ofthe pressure ofthe air inside the pneumatic channel, wherein the apparatus comprises a turbine fan connected to the control unit and located in the housing of the elec­ tro-mechanical device for pressurizing atrnospheric air to a determined pressure level value, and wherein 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 longitudi­ nally extending from said inlet portion to said outlet portion.
