Abstract
Techniques are described for non-invasive, dual-altitude-based measurement of blood pressure of a user using a portable electronic device having a sensor head. Illumination is projected into a body part and received by photodetectors. A changing amount of illumination received by the photodetectors changes corresponds to a changing amount of blood volume in elastic circulatory system pathways in the body part. Measurements of the received illumination are obtained at multiple altitudes relative to the user's heart. A linear fit is applied to the multiple measurements based on at least a predetermined slope-calibration factor to obtain a slope-corrected mean blood pressure measurement (BPM). Some embodiments use similar techniques to further measure pulse-to-mean (PTM) at multiple altitudes. The PTM measurements are used to simulate a systolic and/or diastolic BPM.
