Final answer:
To bring in the RVOT in PLAX, position the ultrasound probe at the left sternal border and angle it towards the left shoulder. The RVOT is visualized as a circular or oval structure just below the aortic valve and above the mitral valve.
Step-by-step explanation:
In order to bring in the RVOT (right ventricular outflow tract) in PLAX (parasternal long axis view), you need to position the ultrasound probe at the left sternal border on the fourth or fifth intercostal space. From this position, you should angle the probe towards the left shoulder to visualize the RVOT.
In the PLAX view, the RVOT is typically seen as a circular or oval structure just below the aortic valve and above the mitral valve. It is important to note that the RVOT can be visualized more clearly in the apical four-chamber view, so it's recommended to switch to that view if necessary.
Here is an example of how the RVOT looks in the PLAX view:
