Better clarity : The act of inhaling/exhaling affects the flow of blood to your heart. By emphasizing a particular activity such as exhaling valve function in your heart can be better evaluated.

Ultrasound: When you inhale your lungs fill with air which scatters the ultrasound beam. We have folks exhale to minimize the beam interference that more air in the lungs causes.
