System and Method for using Demographic Data to Derive a Pulse Wave Velocity-Blood Pressure Transform

摘要

A system and method are provided for using demographic data to derive a PWV-BP transform. The method provides a PWV measurement device with a non-transitory memory, processor, and a calibration application for supplying pseudo-calibrated PWV values. The method loads into the memory a first database of information cross-referencing age compared to central-aortic PWV-BP transforms, a second database of information cross-referencing age and gender compared to systolic and diastolic blood pressure, and a third database of information cross-referencing age as compared to whole-arm PWV. Whole-arm PWV measures a distance between a superasternal notch and index finger, divided by a transit time of an arterial pulse from to heart to the index finger tip. After accepting age and gender data from a first user, the calibration application interpolates the information from the first, second, and third databases, and derives a pseudo-calibrated whole-arm PWV-BP transform for the first user.

1. A method for using demographic data to derive a pulse wave velocity-blood pressure (PWV-BP) transform, the method comprising:
providing a PWV measurement device comprising a non-transitory memory, processor, and a calibration application enabled as a sequence of processor executable steps for providing pseudo-calibrated PWV values; loading into the memory a first database cross-referencing age and central-aortic PWV-BP transforms; loading into the memory a second database cross-referencing age and gender with systolic and diastolic blood pressure; loading into the memory a third database cross-referencing age and whole-arm PWV, where whole-arm PWV measures a distance between a superasternal notch and index finger, divided by a transit time of an arterial pulse from to heart to the index finger tip; accepting age and gender data from a first user; the calibration application interpolating the information from the first, second, and third databases, and deriving a pseudo-calibrated whole-arm PWV-BP transform; and, supplying the pseudo-calibrated whole-arm PWV-BP transform for the first user.
