I. Pressure-Volume Loop Basics

B. Examine P-V Variables Under Normal Conditions

The simulator will display a normal pressure-volume loop. Enter the values (pressure in mmHg, volume in ml, cardiac output in liters/minute) requested in the Instructions box. Round to the nearest integer for pressure and volume; cardiac output should have one decimal place.

Click on the graph to get the coordinate values.
