Simulations are created and interactively controlled using menu selections displayed on QCP’s main menu. The terms simulation and solution (of the model’s equations) are used interchangeably here.

Controlling A Solution

Solutions are calculated as a function of time. The Go main menu selection is used to advance time.

Available solution intervals are shown above.

During calculation, the solution may be interrupted using the main menu’s Stop selection. The solution may then be resumed using the Continue selection.

The Restart main menu selection resets the model to initial conditions.

Viewing The Results

The numerical values calculated during a simulation are displayed in many different formats including formatted numerical values, x-y graphs, bargraphs, functions of time, and qualitative values.

The sample above shows time displayed as a clock and calendar, blood pressure displayed numerically and a graph of systolic and diastolic pressure as a function of time during a 5 minute control period, 5 minutes of exercise bike at 150W, and 5 minutes of recovery.

The calculator button evokes a calculator that can be used to convert blood pressure among the commonly used physical units.

Controlling The Display Of Results

The display of results is controlled by the toolbar buttons immediately below the main menu (shown above).

Button groups may be added to and removed from the toolbar by clicking menu selections in the View menu.

A check indicates that the group is now displayed on the toolbar.

Changing Parameters

A variety of devices, including radiobuttons and slidebars are used to change QCP’s parameters.

The figure above shows the radiobuttons used to turn on an insulin pump and the slidebar used to set the infusion rate.
