Slide 1: What is the labeled object on this chest radiograph?

Slide 2: A pulmonary artery (Swan-Ganz) catheter. What is it used for? One. Invasive hemodynamic monitoring – e.g. pulmonary capillary wedge pressure (PCWP). Two. SvO2 measurement.

Slide 3: Is it correctly positioned? PA catheters are ideally placed within the proximal left or right main pulmonary artery. The catheter tip should be within 2 cm of the hilum and must be retracted if it extends beyond the hilar border.
