You need to perform an ultrasound on your patient. You walk up to the ultrasound and upon grabbing the machine, you notice it’s stuck! You look down and realize the ultrasound probe cable (particularly the linear probe) is impeding the wheel from rolling.

Imagine a busy evening shift interrupted by the news that the unstable dialysis patient still has no access. Begrudgingly, you drag the ultrasound into the patient’s room. Buried beneath a layer of muscle, a tiny vein lurks below an intimidating artery with a nerve nestled close by. Making matters worse, the patient is becoming increasingly more frustrated. “This always happens. I told them not to remove my last PICC line,” he notes.
