1. A method for controlling alarms in a physiological monitoring apparatus, the method comprising:

  • observing a level of a physiological signal obtained from a subject;

    in response to detecting a change of the level of the physiological signal to a predetermined value range representing low signal values, determining signal morphology for the physiological signal, thereby to obtain reference morphology for the physiological signal;

    monitoring the signal morphology when the physiological signal remains in the predetermined value range; and

    suppressing alarms when the signal morphology fulfills predefined criteria with respect to the reference morphology and the level of the physiological signal remains in the predetermined value range.
