An alarm system can include one or more processors. Such processors can receive physiological parameter data associated with a patient. The one or more processors can also select an alarm pattern based at least in part on an indicator of an attribute of the patient. The alarm pattern can include a plurality of different thresholds and corresponding periods of time. Further, the one or more processors can generate an alarm when a value associated with the physiological parameter data satisfies at least one threshold of the plurality of thresholds for the period of time corresponding to the at least one threshold.
