Method and apparatus for controlling an alarm while monitoring
First Claim
1. A method for monitoring of a patient, comprising:
- acquiring data from a patient;
dynamically adjusting an alarm criteria based on the data;
determining a first value that is typical for the patient for the characteristic being monitored;
determining a second value for the characteristic being monitored;
generating a comparison based on the first value and the second value;
measuring a slope based on first and second data with respect to time;
determining a plurality of slopes of data value with respect to time and determining the degree of correlation of the slopes, wherein the determining the degree of correlation of the slopes comprises determining a mean slope value and a standard deviation of the slope values; and
sending an alarm if the mean slope value exceeds a threshold, wherein the alarm that is sent if the mean slope exceeds a threshold is only sent if the standard deviation of the slope values also exceeds a threshold.

Abstract
A method for monitoring a subject can include acquiring data from the subject, and dynamically adjusting an alarm limit based on the data. The method can also comprise determining a first value that is typical for the subject for the characteristic being monitored, determining a second value for the characteristic being monitored, and generating a comparison based on the two values. The method could also comprise setting a threshold for a characteristic being monitored, and decreasing the alarm limit if the data crosses the threshold. The method could also include setting an extremity limit. The following methods can be applied to the monitoring of a healthcare patient, or other subjects of interest. Also, the values used in the monitoring of the subject can be configured to be transferable from one monitor to another.

3. A method for sending an alarm using a medical monitor that is monitoring a patient, comprising:
-
acquiring first data from a patient; acquiring second data from a patient; generating a comparison of the first data to the second data, wherein the monitor is configured to generate an alarm based on the comparison; measuring a slope based on first and second data with respect to time; determining a plurality of slopes of data value with respect to time and determining the degree of correlation of the slopes, wherein the determining the degree of correlation of the slopes comprises determining a mean slope value and a standard deviation of the slope values;
andsending an alarm if the mean slope value exceeds a threshold, wherein the alarm that is sent if the mean slope exceeds a threshold is only sent if the standard deviation of the slope values also exceeds a threshold. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A monitoring system for monitoring a patient, the system comprising:
-
a data acquisition device configured to collect a set of data from the patient; a processor configured to dynamically adjust an alarm criteria based on the set of data collected from the patient, wherein the processor is further configured to determine a first value and a second value from the collected data that is typical for the patient for a characteristic being monitored, and wherein the processor is further configured to generate a comparison based on the first value and the second value, and further wherein the processor is configured to measure a slope based on first and second data with respect to time to determine a plurality of slopes of data value with respect to time and determine the degree of correlation of the slopes, wherein determining the degree of correlation of the slopes comprises determining a mean. slope value and a standard deviation of the slope values and to send an alarm if the mean slope value exceeds a threshold, wherein the alarm that is sent if the mean slope exceeds a threshold is only sent if the standard deviation of the slope values also exceeds a threshold. - View Dependent Claims (14, 15)
