First Claim
Patent Images
1. A method of operating a medical system, the method comprising:
- displaying a preprogrammed menu on a display, the menu displaying an alert criteria used to assess a change in patient status and further displaying one or more corresponding alert criteria setting for the displayed alert criteria;
the displayed alert criteria settings including at least a baseline respiration rate displayed in a first pull-down menu and an allowed increase over the baseline respiration rate displayed in a second pull-down menu;
receiving an input from a user to change one or more of the alert criteria settings via the corresponding pull-down menu, and displaying the changed alert criteria settings via the menu;
configuring alert criteria for assessing the change in patient status based at least in part on the alert criteria settings;
sensing respiration and storing respiration data;
determining a respiration parameter from the respiration data;
assessing the change in patient status including comparing a measure related to the respiration parameter to the configured alert criteria; and
generating a signal indicating the change in patient status responsive to the comparison.

Abstract
Changes in patient status are assessed based at least in part on respiration parameters. A user can make selections regarding alert criteria options to be used in assessing patient status. Respiration is implantably sensed and respiration data is stored by an implantable device. A respiration parameter, such as respiration rate, is measured from the respiration data. The change in patient status is assessed by comparing the respiration parameter to the configured alert criteria. If the comparison of the respiration parameter and the configured alert criteria indicates a significant change in patient status, an alert signal is generated.

11. A system for evaluating patient status, the system comprising:
-
input and output circuitry configured to display alert criteria threshold values on a display, wherein the alert criteria threshold values are displayed in a menu on the display, the input and output circuitry further configured to receive input from a user to change at least one of the displayed alert criteria threshold values using the menu, and to display the at least one changed alert criteria threshold value in the menu; sensors configured to implantably sense one or more physiological signals, including respiration; circuitry configured to determine one or more parameters of the physiological signals, the one or more parameters comprising at least two of a maximum respiration rate, a minimum respiration rate, and a median respiration rate; and an alert module configured to compare the one or more parameters to corresponding ones of the alert criteria threshold values, and to generate an alert signal based on the comparison. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A system for evaluating a patient'"'"'s status, the system comprising:
-
one or more sensors configured to implantably sense one or more physiological signals; hardware configured to; determine one or more parameters of the physiological signals; display alert criteria settings for an alert in an alert criteria settings menu displayed on a display, wherein the alert criteria setting menu allows a user to change one or more of the alert criteria settings by interacting with the menu, and then displaying the changed alert criteria settings on the menu; compare the one or more determined parameters to the alert criteria settings set by the user via the menu, and to generate an alert signal based on the comparison; and display a menu item that allows the user to enable or disable the alert. - View Dependent Claims (21, 22)
