METHOD FOR AUTOMATIC SETTING TIME VARYING PARAMETER ALERT AND ALARM LIMITS
First Claim
Patent Images
1. A method of providing a time-varying physiological parameter alert, comprising:
- monitoring a physiologic parameter, patient data, or clinical information of a patient;
comparing the monitored parameter to an initial threshold criteria;
following a drug administration, intervention or therapy administration event, temporarily changing the initial threshold criteria to a worsened condition threshold criteria that permits worsening of the monitored parameter for an allotted time period and to a post-administration threshold criteria after the allotted time period;
during the allotted time period, comparing the monitored parameter to the worsened condition threshold criteria;
after the allotted time period, comparing the monitored parameter to the post-administration threshold criteria; and
in response to the monitored parameter violating one or more of the initial threshold criteria, the worsened condition threshold criteria, and the post-administration threshold criteria, triggering an alarm.

Abstract
When monitoring physiological parameters (e.g., blood pressure, heart rate, etc.) of a patient, a threshold limit (30) is set (e.g., automatically or manually) and the monitored parameter is continuously compared to the threshold limit, which may be constant or may vary with time. An alarm (36) is triggered if the monitored parameter exceeds the threshold limit at any time, or if the monitored parameter has not reached a target value by the end of a predefined time period by which an administered drug or therapy should have been effective.

12. A system that provides a time-varying physiological parameter alert to a user;
- comprising;
one or more sensors that monitor a physiological parameter of a patient; a processor programmed to; receive one or more of patient data, clinical lab data, and monitored data or measurements that describe the physiological parameter; compare the monitored parameter to an initial threshold criteria; following a drug administration, intervention or therapy administration event, temporarily change the initial threshold criteria to a worsened condition threshold criteria that permits worsening of the monitored parameter for an allotted time period and to a post-administration threshold criteria after the allotted time period; during the allotted time period, compare the monitored parameter to the worsened condition threshold criteria; after the allotted time period, compare the monitored parameter to the post-administration threshold criteria; and in response to the monitored parameter violating one or more of the initial threshold criteria, the worsened condition threshold criteria, and the post-administration threshold criteria, trigger an alarm. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
