Respiratory apparatus comprising a ventilation mask and means for supplying breathable gasses, under pressure, thereto and means for exhausting gases therefrom, is characterised in that the pressuring means is provided substantially at the inlet of the mask, thereby substantially reducing the length of the air supply hose to a ventilation mask, so that problems associated with high pressures and large volumes of dead space can be alleviated. |
