Patent ID: RE41332

Claim:
A method for displaying data gathered from a subject during a cardiopulmonary exercise test and computed relationships based on that data, comprising the steps of plotting, on a first graph having an x-axis, a first y-axis and a second y-axis, {dot over (V)}O 2 on the x-axis, heart rate on the first y-axis, and calculated stroke volume on the second y-axis using a computer; displaying the first graph on a display; plotting, on a second graph having an x-axis, a first y-axis and a second y-axis, {dot over (V)}CO 2 on the x-axis, {dot over (V)}E on the first y-axis, and SaO 2 on the second y-axis using a computer; displaying the second graph on a display; plotting, on a third graph having an x-axis, a first y-axis and a second y-axis, {dot over (V)}O 2 on the x-axis, {dot over (V)}CO 2 on the first y-axis, and ratios {dot over (V)}/{dot over (V)}CO 2 {dot over (V)}E/{dot over (V)}CO 2 and {dot over (V)}E/{dot over (V)}O 2 on the second y-axis using a computer; displaying the third graph on a display; plotting, on a fourth graph having an x-axis, a first y-axis and a second y-axis, time on the x-axis, heart rate on the first y-axis and {dot over (V)}O 2 on the second y-axis by using a computer; and displaying the fourth graph on a display.
