(+15 %), 144 (+20 %), and 180 (+50 %). Each push of the decrease softkey sets the
pressure down from 180 to 120 mmHg with the same pressure steps.
3. Push the Pullback softkey to simulate the pull back of the IBP channel 2 catheter to
the left ventricle.
Pulmonary Valve Catheterization Simulation
The pulmonary valve controls flow from the right ventricle (RV) to the pulmonary artery
(PA) and prevents flow in the reverse direction. Both IBP channels are set to PA 25/10.
IBP channel 1 stays at PA 25/10 for reference throughout the simulation.
1. Push the Insert softkey to simulate the insertion of the IBP channel 2 catheter into
the right ventricle at 25/0.

Figure 24. Pulmonary Valve Catheterization Simulation Screen
For a normal valve, when the heart beat starts, the RV pressure increases to
10 mmHg. Then, as the valve opens, both pressures increase to the systolic peak.
Next, the pressures fall until the valve opens. The RV pressure goes back down, but
the pulmonary artery stays at 10 mmHg.
2. Push the Increase Pressure or Decrease Pressure to simulate a bad pulmonary
valve. There are six pressure values between 25 and 38 mmHg. Each push of the
increase softkey sets the left ventricle pressure to 26 (+5 %), 28 (+10 %), 29 (+15 %),
30 (+20 %), and 38 (+50 %). Each push of the decrease softkey sets the pressure
down from 38 to 25 mmHg with the same pressure steps.
3. Push the Pullback softkey to simulate the pull back of the IBP channel 2 catheter to
the right ventricle.
Mitral Valve Cahteterization Simulation
The mitral valve controls flow from the left atrium (LA) to the left ventricle (LV) and
prevents flow in the reverse direction. A mitral valve test is done indirectly with pressure
measurements in the pulmonary artery (PA). There are two measurements: normal and
wedged. A wedged measurement is done with a inflated ballon (PAW) in the pulmonary
artery to measure the back pressure from the left ventricle through the left atrium and the
lungs. At the start of the procedure, IBP channel 1 is set to LV 120/0 and channel 2 is set
to pulmonary artery (PA) 25/10/. IBP channel 1 stays at LV 120/0 for reference
throughout the simulation.
1. Push the Insert softkey to simulate a change in IBP channel 2 catheter pressure to
the pulmonary artery wedge pressure (PAW) of 10/2.
