Blood pressure monitor with compensation for physique and method of use
First Claim
1. In an apparatus for determining the blood pressure of a user, comprising an inflatable cuff means for encircling a portion of the user'"'"'s body, an inflation means for controllably inflating and deflating said cuff means, pressure variation sensing means for monitoring blood circulation of said user during inflation and deflation of said cuff means, determining means responsive to said pressure variation sensing means for determining the blood pressure of said user including measuring means for measuring the diastolic and systolic blood pressure of said user and means for communicating the output of said determining means to said user, the improvement comprising:
- data entry means for inputting data representative of a parameter of the physique of the user,wherein said determining means includes means responsive to said data entry means for applying a correction to the output of said measuring means to correct the output of said determining means.

Abstract
An automated blood pressure measurement apparatus and method which includes an inflatable cuff at a predetermined height relative to where a user must sit or stand in order to comfortably use the apparatus including a correction arrangement which provides a numerical correction for a hydrostatic pressure differential between the heart level of a user in a posture implied by the predetermined height of the cuff based on the user'"'"'s overall height and a standard posture for measuring blood pressure at which the cuff height is at approximately the same level as the heart level when blood pressure is measured.
