System and method for obtaining an objective measure of dyspnea
First Claim
1. A computer-implemented method for assessing a level of dyspnea in a patient, the method comprising:
- measuring physical activity of the patient over a period of time with an activity monitor to gather physical activity data;
measuring respiration rate of the patient over the period of time with a respiration rate sensor to gather respiration rate data;
administering, with a computer processor, a questionnaire to gather clinical information of the patient;
determining, with the computer processor, a first baseline parameter reflecting a respiration rate of the patient at rest based on the respiration rate data and/or the physical activity data;
determining, with the computer processor, a second baseline parameter reflecting a respiration rate of the patient during activity based on the respiration rate data and/or the physical activity data; and
determining, with the computer processor, a dyspnea value for the patient based on the first baseline parameter, the second baseline parameter, and the clinical information of the patient, the dyspnea value being representative of the level of dyspnea in the patient, and wherein the dyspnea value is determined such that responsive to the measured respiration rate being greater than a sum of the respiration rate at rest and a first predetermined constant, and the physical activity level of the patient being lower than a predetermined activity level, the dyspnea value indicates the patient is experiencing dyspnea.

Abstract
A computer-implemented method for assessing a level of dyspnea in a patient is provided. The method includes measuring physical activity of the patient over a period of time with an activity monitor to gather physical activity data; measuring respiration rate of the patient over the period of time with a respiration rate sensor to gather respiration rate data; administering a questionnaire to gather clinical information of the patient; and executing, on one or more computer processors, one or more computer program modules to determine a dyspnea value for the patient based on the respiration rate data, the physical activity data, and the clinical information of the patient. The dyspnea value is representative of the level of dyspnea in the patient.
