Abstract

An arrangement for supervising a medical monitor. The arrangement for supervising the medical monitor comprises a measurement function having at least one measurement device to make at least one measurement for obtaining measurement information for monitoring one or more patient care signals. The arrangement for supervising the medical monitor also includes a supervision analyzer configured to communicate with the measuring function and to receive the measurement information. The supervision analyzer is adapted to obtain reference information and to compare the measurement information to the reference information to determine whether the measurement function is working properly.

Claims

1-15. -15. (canceled)

16. An arrangement for supervising a medical monitor, the arrangement comprising:

a measurement function having at least one measurement device to make at least one measurement for obtaining measurement information from one or more monitored patient care signals; and

a supervision analyzer configured to communicate with the measuring function and to receive the measurement information;

wherein the supervision analyzer is adapted to obtain reference information,

wherein the reference information is created

(a) when the measurement function measures a patient care signal different from the one or more monitored patient care signals or

(b) when the measurement function exploits only some measurement components of the one or more patient care signals and the patient care signal, and

wherein the supervision analyzer is further configured to compare the measurement information to the reference information to determine whether the measurement function is working properly.

17. The arrangement according to claim 16, wherein the at least one measurement device is one of a first measurement device, a second measurement device and a third measurement device.

18. The arrangement according to claim 17, wherein the first measurement device is adapted to make a gas measurement of a respiration gas, which gas measurement includes at least identification of a gas component or analysis of a concentration of a gas component.

19. The arrangement according to claim 17, wherein the second measurement device is adapted to measure a pressure of a respiration gas.

20. The arrangement according to claim 17, wherein the third measurement device is adapted to monitor a tissue component such as a blood oxygenation level and/or a pulse rate.

21. The arrangement according to claim 16, wherein the measurement information is obtained from one measurement device and the reference information is created by a different measurement device.

22. The arrangement according to claim 16, wherein the reference information created by the different measurement device is from a vaporizer indicating an anesthetic agent type.

23. A method for supervising a medical monitor, the method comprising:

activating the medical monitor to make a measurement indicative of one or more patient care signals to create measurement information;

creating reference information by exploiting only some measurement components of the one or more patient care signals and a separate patient care signal;

supplying the measurement information and the reference information to a supervision analyzer;

comparing, using the supervision analyzer, the measurement information to the reference information; and

determining whether or not the measured information is acceptable; and

choosing one of continue as planned or take action.

24. The method according to claim 23, wherein the determining is adapted to take into account a comparison acceptability limit.

25. The method according to claim 23, wherein the determining is based on the comparing and a comparison acceptability limit.

26. The method according to claim 23, wherein choosing to continue as planned includes keeping a monitor operation unchanged.

27. The method according to claim 23, wherein choosing to take action includes giving an alarm signal.

28. The method according to claim 23, wherein activating the medical monitor to make a measurement comprises:

taking a gas measurement of a respiration gas, the gas measurement having at least one of identification of a gas component or analysis of a concentration of a gas component;

taking a pressure measurement of a respiration gas, or

monitoring a tissue component such as a blood oxygenation level and/or a pulse rate.
