How can you make a TR jet more prominent during Doppler echo?

Methods to make a TR jet more prominent

You can make a TR jet more prominent by deep inspiration or passive leg raising which increases the right sided inflow. This may not work is the right heart is grossly overloaded.

Another method is to give agitated saline used for contrast echo, which also makes the TR (tricuspid regurgitation) jet more prominent. Sometimes it is possible to enhance TR jets by adjusting the gain and reject settings of the echocardiograph.
