This document describes techniques and apparatuses enabling determination of health state trends for a consistent patient situation. Various noninvasive health monitors can be used to sense a patient s situation and health states including disease progression at those states. These noninvasive health monitors may also act passively and in a patient s normal course of life which enhances many patient s desire to submit to monitoring as well as increase consistency of use as in many cases the patient does little or nothing to cause his or her health monitoring and health trend determination. With health states determined for a consistent patient situation more accurate and more robust health trends can be determined. In particular parameters like cardiac rhythm respiration rate or the spine curvature can be determined using a radar based motion sensing system located in the vicinity of a patient s bed.
