Wasserman 9-Panel Plot

The Wasserman 9-Panel Plot (pronounced: wass-er-man nine-pan-el plot) is a graphical representation used in the field of Cardiopulmonary Exercise Testing (CPET). It is named after the renowned American physiologist, Karlman Wasserman, who developed this method.

Etymology

The term "Wasserman 9-Panel Plot" is derived from the name of its creator, Karlman Wasserman, and the nine panels or graphs that make up the plot.

Definition

The Wasserman 9-Panel Plot is a comprehensive graphical representation that displays nine different parameters measured during a CPET. These parameters include oxygen uptake (VO2), carbon dioxide production (VCO2), ventilation (VE), heart rate (HR), oxygen pulse (O2 Pulse), ventilatory equivalents for oxygen (VE/VO2), ventilatory equivalents for carbon dioxide (VE/VCO2), end-tidal oxygen pressure (PETO2), and end-tidal carbon dioxide pressure (PETCO2).

Usage

The Wasserman 9-Panel Plot is primarily used to evaluate the cardiorespiratory fitness and the physiological response to exercise in patients. It is particularly useful in diagnosing and managing conditions such as heart disease, lung disease, and exercise intolerance.
