Method for supply of respiratory gas in which the gas is sucked from the surroundings and supplied to a breathing mask using two piston-cylinder bellows type transport units. The stroke of the transport units are phase displaced relative to each other so that a pressure is supplied by the second transport unit (14) before the return stroke of the first transport unit (13) begins. The invention also relates to a corresponding respiratory gas supply device. |
