6-30 Cardiology
Operating Procedures
1. Select [RVSP] in the measurement menu.
2. Measure TR Vmax in Doppler mode.
The TR PGmax is calculated.
3. Select [RAP] in the [RVSP] sub-menu, and select (or enter) the pressure in the dialog box
popped up. As shown in figure below:
Range of input values is [0, 50.0mmHg].
4. Click [OK] after selecting (or inputting) the pressure, the RAP is obtained.
RVSP is calculated.
