  • Machine Positioning: Position the ultrasound machine on the right side of the patient with the screen facing you. With this configuration you can face both the patient and the ultrasound screen, scanning with your right hand and manipulating buttons on the machine with the other hand. Also position a chair at the foot of the bed to sit in while performing the scan.
