Abstract

An emergency oxygen system is provided for aircraft passengers. The system includes at least one oxygen mask (2), with a sensor (4) for detecting at least one breathing characteristic value of a passenger using this oxygen mask (2). A control unit (10) individually determines the oxygen requirement of the passenger on account of the detected breathing characteristic value. A dosing device (8) is actuated by the control unit (10). The dosing device (8) supplies an oxygen quantity corresponding to the determined oxygen requirement, to the oxygen mask (2).
