Non-invasive determination of disease states
First Claim
Patent Images
1. A method for estimating a disease state for a patient, the method comprising:
- capturing images of an unobstructed portion of the patient;
processing the images to detect a pulse rate;
determining a pulse rate variability based upon the pulse rate; and
calculating an early warning score using the pulse rate variability, including;
comparing the pulse rate variability to a baseline having similar demographics; and
increasing or decreasing the early warning score based upon a variance from the baseline.

Abstract
An example method for estimating a disease state for a patient can include: capturing physiological data including images from the patient over time; processing the physiological data to detect a variability; comparing the variability to a baseline or a range; and estimating the disease state for the patient based upon the comparing of the variability to the baseline or the limit.
