SYSTEM AND METHOD FOR A NON-SUPINE EXTREMITY BLOOD PRESSURE RATIO EXAMINATION
First Claim
1. An apparatus that facilitates the determination of a hydrostatic correction factor usable in 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 apparatus comprising:
- a computational device; and
an input element coupled to the computational device, wherein information relating to a vertical distance between the first and second blood pressure measuring devices is receivable by the input element;
the computational device being operable to calculate at least one of a hydrostatic correction factor, a corrected extremity blood pressure, and an extremity blood pressure ratio using the information relating to the vertical distance.

Abstract
The present invention provides apparatuses and 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 first blood pressure measuring device may be positionable on a first extremity of the patient, and a second blood pressure measuring device may be positionable on a second extremity of the patient, with one of the blood pressure measuring devices being located above the other one. The apparatus includes a computational device and an input element coupled to the computational device, wherein information relating to a vertical distance between the first and second blood pressure measuring devices is receivable by the input element. The computational device is operable to calculate at least one of a hydrostatic correction factor, a corrected extremity blood pressure, and an extremity blood pressure ratio using the information relating to the vertical distance.
