Abstract

A graphical method of displaying interrelated blood pressure data that effectively communicates patient or group performance within or between discrete datasets. The graphical method displays Systolic Pressure (SP), Diastolic Pressure (DP), Pulse Pressure (PP), Mean Arterial Pressure (MAP) and the Classification of Blood Pressure as related to a single data point or a plurality of data points from a discrete dataset. Multiple datasets can be simultaneously displayed for comparison purposes allowing patients, physicians or scientists to understand the relative differences in dataset performance across a series of datasets.

Claims

1. An interrelated graphical method for displaying blood pressure data within a single graph that simultaneously displays the parameter magnitude values of systolic pressure, diastolic pressure, pulse pressure, mean arterial pressure, and a classification of blood pressure category, from a plurality of said categories, for every graphed data point.

2. The method of claim 1 wherein a coordinate system with reference lines is utilized to reference the parameter magnitude values of all plotted data points.

3. The method of claim 2 wherein the systolic pressure and diastolic pressure parameter reference lines are projected as straight lines at right angles to the respective parameter axis.

4. The method of claim 2 wherein the pulse pressure parameter reference lines are projected as a series of parallel lines emanating from the systolic pressure axis at an angle equal to that angle imposed by a zero pulse pressure reference line created by connecting plotted points with a straight line that mathematically satisfy the pulse pressure equation where the difference between a systolic pressure and a diastolic pressure axis magnitude value is equal to zero.

5. The method of claim 2 wherein a mean arterial pressure reference line is projected as a straight line emanating from the zero pulse pressure reference line at an angle imposed by connecting plotted points that mathematically satisfy the mean arterial pressure equation for several unknown values of diastolic pressure while maintaining the mean arterial pressure equation value as a mathematical constant and while varying the systolic pressure equation value accordingly;

the magnitude value of resulting mean arterial pressure reference line will correspond to the mathematical constant value utilized to calculate said plotted points.

6. The method of claim 5 wherein as series of mean arterial pressure reference lines are established at appropriate intervals so that all mean arterial pressure reference lines are parallel and appropriately labeled.

7. The method of claim 1 wherein data points are plotted at the graphical intersections of any two of the following parameter magnitude values form a plurality of unique blood pressure measurements:

systolic pressure, diastolic pressure, pulse pressure and mean arterial pressure.

8. The method of claim 1 wherein a specific area is established to designate optimal pressure for data points residing within said specific area.

9. The method of claim 1 wherein a plurality of data is segregated and identified as a discrete dataset and displayed as a unique population of graphed data points.

10. The method of claim 9 wherein a plurality of datasets are simultaneously displayed and individually identified by different colors, geometric shapes or a combination of color and geometric shape, and displayed accordingly.

11. The method of claim 1 whereby computer software is utilized to input, organize and maintain data, perform calculations and display data utilizing the graphical method.
