The study is better to perform from a Parasternal Approach, short axis of the heart, at the level of the Pulmonary Artery. The Sample Volume is placed in the Pulmonary Artery (1 cm distal of the Pulmonary Artery Valve).

Flow occurs in the diastole phase and is directed away from the transducer, and located below the Baseline. The flow, in contrast to the aortic, has a small amplitude.
