To simulate a Cardiac Catheterization procedure:
1. Push the Tests softkey in the IBP screen.
2. Push  or  to highlight Cardiac Catheterization.
3. Push . The valve selection is shown in the display.
To change the valve value:
1. Push .
2. Push  or  to highlight Aortic, Pulmonary, or Mitral.
3. Push  to go back to the IBP: Cardiac Catheterization screen.
To start the procedure simulation:
1. Push the Start softkey.
All the procedure steps are done manually.
2. Push the Insert softkey for the next step.
3. You simulate an increase and decrease of simulated pressure when you push the
Increase Pressure or Decrease Pressure softkeys.
4. Push the Pullback softkey to simulate the pressures when the catheter is pulled
back.
Push the Stop softkey to stop the procedure and go back to the IBP: Cardiac
Catheterization screen.
Aortic Valve Catheterization Simulation
The aortic valve controls flow from the left ventricle (LV) to the aorta (atrial pressure)
and prevents flow in the reverse direction. Both IBP channels are set the Arterial 120/80.
IBP channel 1 stays at arterial 120/80 for reference throughout the simulation.
1. Push the Insert softkey to simulate the insertion of IBP channel 2 catheter into the
left ventricle at 120/0. Figure 23 shows the screen for the aortic valve catheterization
simulation.

Figure 23. Aortic Valve Catheterization Simulation Screen
For a normal valve, when the heart beat starts, the LV pressure increases to 80
mmHg. Then, as the valve opens, both pressures increase to the systolic peak. Next,
the pressures fall until the valve opens. The LV pressure goes back down, but the
arterial stays at 80 mmHg.
2. Push the Increase Pressure or Decrease Pressure to simulate a bad aortic
valve. There are six pressure values between 120 and 180 mmHg. Each push of the
increase softkey sets the left ventricle pressure to 126 (+5 %), 132 (+10 %), 138
