Abstract

Combination level alarms and alarm persistence for patient monitoring, as well as related methods and apparatus, are disclosed. For a combination level alarm, respective values for multiple physiological conditions are received. A determination is made as to whether the received values satisfy respective alarm criteria for the physiological conditions, and if so, an alarm is raised. An alarm persistence feature involves periodically receiving values of a physiological condition, and determining whether the received values have satisfied an alarm criterion for at least a predetermined portion of a predetermined period of time. If so, an alarm is maintained. Combination alarms and alarm persistence may be implemented individually or together.

Claims

1. A method comprising:

periodically receiving values of a physiological condition from a sensor;

determining whether the received values have satisfied an alarm criterion for at least a predetermined portion of a predetermined period of time; and

maintaining an alarm where the received values have satisfied the alarm criterion for at least the predetermined portion of the predetermined period of time.

2. The method of claim 1, wherein the received values indicate values of the physiological condition at respective times, and wherein determining comprises determining whether at least a minimum number of the received values that indicate values of the physiological condition during a time period equal to the predetermined period of time immediately preceding a time of a most recently received value satisfied the alarm criterion.

3. The method of claim 1, further comprising:

periodically receiving values of a further physiological condition from a further sensor,

wherein determining further comprises determining whether the received values of the further physiological condition have satisfied a further alarm criterion for at least the predetermined portion of the predetermined period of time, and

wherein maintaining comprises maintaining the alarm where both the received values of the physiological condition have satisfied the alarm criterion for at least the predetermined portion of the predetermined period of time and the received values of the further physiological condition have satisfied the further alarm criterion for at least the predetermined portion of the predetermined period of time.

4. The method of claim 1, wherein maintaining comprises maintaining an indication of the alarm in a GUI (Graphical User Interface).

5. A computer readable medium having computer readable instructions stored thereon that when executed implement the method according to claim 1.

6. Apparatus comprising:

a sensor interface that enables the apparatus to periodically receive values of a physiological condition from a sensor; and

an analysis module, operatively coupled to the sensor interface, that determines whether the received values have satisfied an alarm criterion for at least a predetermined portion of a predetermined period of time, and maintains an alarm where the received values have satisfied the alarm criterion for at least the predetermined portion of the predetermined period of time.

7. The apparatus of claim 6, wherein the received values indicate values of the physiological condition at respective times, and wherein the analysis module determines whether the received values have satisfied the alarm criterion for at least the predetermined portion of the predetermined period of time by determining whether at least a minimum number of the received values that indicate values of the physiological condition during a time period equal to the predetermined period of time immediately preceding a time of a most recently received value satisfied the alarm criterion.

8. The apparatus of claim 6, wherein the sensor interface further enables the apparatus to periodically receive values of a further physiological condition from a further sensor, and wherein the analysis module further determines whether the received values of the further physiological condition have satisfied a further alarm criterion for at least the predetermined portion of the predetermined period of time and maintains the alarm where both the received values of the physiological condition have satisfied the alarm criterion for at least the predetermined portion of the predetermined period of time and the received values of the further physiological condition have satisfied the further alarm criterion for at least the predetermined portion of the predetermined period of time.

9. The apparatus of claim 6, further comprising:

a user interface, operatively coupled to the analysis module, that enables interaction with a user through a GUI (Graphical User Interface),

wherein the analysis module maintains the alarm by maintaining an indication of the alarm in the GUI.

10. The apparatus of claim 6, wherein the sensor is located remotely from the apparatus.
