25:

• The monitoring device of claim 22, wherein the false alarm analyzer is configured to produce the count by estimating, based on the measurement signal, a respective number of false alarm indications generated by the disruption detector for each of a plurality of different configurations of the disruption detector.

26:

• The monitoring device of claim 22, wherein the false alarm analyzer is configured to compare at least part of a time-sequence of parameter values to an allowable range among a plurality of allowable ranges, identify a respective false alarm indication when a set of parameter values in the time-sequence of parameter values falls outside a respective allowable range, and produce the count to represent the number of false alarm indications for the respective allowable range.

27:

• The monitoring device of claim 26, wherein the updater is configured to set a current allowable range as a function of the allowable range for which the count meets a desired value.

28:

• The monitoring device of claim 27, wherein the updater is configured to update the configuration of the disruption detector by increasing or decreasing the current allowable range as a function of the count.

29:

• The monitoring device of claim 28, wherein the updater is configured to update the configuration of the disruption detector by repeatedly increasing or decreasing the current allowable range until the count meets a desired value.

30:

• The monitoring device of any one of claim 22, wherein the false alarm analyzer is configured to produce the count to represent the number of false alarm indications among the alarm indications that are generated by the disruption detector over a time period.

31:

• The monitoring device of claim 22, wherein the disruption detector is further configured to, when operating on the measurement signal, perform an automatic validation of each alarm indication to identify the alarm indication as a false alarm indication or a true alarm indication, wherein the false alarm analyzer is configured to produce the count based on the false alarm indications identified by the automatic validation.

33:

• The monitoring device of claim 31, wherein the first fluid containing system comprises a blood processing apparatus for connection, by the fluid connection, to a subject, wherein the sensor comprises a pressure sensor for sensing a pressure of blood in the blood processing apparatus, wherein the automatic validation comprises:
• obtaining and processing the measurement signal for detection of pulsations originating from a pulse generator in or associated with the subject.

34:

• The monitoring device of claim 33, wherein the automatic validation further comprises, before obtaining and processing the measurement signal, generating a control signal to stop one or more pumping device arranged in the blood processing apparatus.

35:

• The monitoring device of claim 31, wherein the alarm module is configured to activate the alarm signal when the automatic validation identifies the alarm indication as a true alarm indication.

36:

• The monitoring device of claim 22, wherein the updater is configured to update the configuration of the disruption detector at fixed time intervals and/or triggered by the count.

37:

• The monitoring device of claim 22, wherein the measurement signal represents fluid pressure in the first fluid containing system, and wherein the parameter values are indicative of one of a pressure level in the first fluid containing system, and pulsations originating from a pulse generator in the second fluid containing system.

40:

• The method of claim 39, further comprising:
• estimating, based on the measurement signal, the number of false alarm indications generated by the detection logic for each of a plurality of different configurations of the detection logic, and producing the count to represent the number of false alarm indications for each of the plurality of different configurations.

41:

• The method of claim 39, further comprising:
• producing the count to represent the number of false alarm indications per unit time among the alarm indications that are generated when operating the detection logic, in a current configuration, on the measurement signal.

42:

• A computer-readable medium comprising processing instructions for causing a data processor to perform the method of claim 39.
