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 locating mechanism fixing a position of at least one of the first and second blood pressure measuring devices relative to its respective patient extremity; and
an instrumentality which provides information about a vertical distance between the first and second blood pressure measuring devices, wherein the vertical distance is usable in determining the hydrostatic correction factor.

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 locating mechanism that fixes a position of at least one of the first and second blood pressure measuring devices relative to its respective patient extremity. The apparatus also includes an instrumentality that provides information about a vertical distance between the first and second blood pressure measuring devices. The vertical distance is usable in determining the hydrostatic correction factor.

28. 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:
-
positioning a locating mechanism relative to the patient, wherein the locating mechanism fixes a portion of at least one of the first and second blood pressure measuring devices positioned relative to its respective patient extremity; measuring the vertical distance between the first and second blood pressure measuring devices; and determining a hydrostatic correction factor for the extremity blood pressure ratio examination. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
