SYSTEM AND METHOD FOR A NON-SUPINE EXTREMITY BLOOD PRESSURE RATIO EXAMINATION
First Claim
1. A method for facilitating the determination of a hydrostatic correction factor for an extremity blood pressure ratio examination of a patient in a non-supine position, wherein a first blood pressure measuring device is positionable to measure a blood pressure present in a first extremity of the patient and a second blood pressure measuring device is positionable to measure a blood pressure present in a second extremity of the patient, one of the blood pressure measuring devices being located above the other blood pressure measuring device, the method comprising the steps of:
- establishing the vertical distance between the first and second blood pressure measuring devices based on an empirically derived formula; and
determining a hydrostatic correction factor for the extremity blood pressure ratio examination based on the vertical distance.

Abstract
The present invention provides methods that facilitate the determination of a hydrostatic correction factor usable in an EBPR examination of a patient in a non-supine position. In one embodiment, a method for facilitating the determination of a hydrostatic correction factor for an extremity blood pressure ratio examination of a patient in a non-supine position includes establishing the vertical distance between first and second blood pressure measuring devices positionable on first and second extremities of the patient based on an empirically derived formula and determining a hydrostatic correction factor for the extremity blood pressure ratio examination based on the vertical distance. In this regard, the formula for the vertical distance may be based on a percentage of the height of the patient.
