IABP – radio-opaque marker

The IABP can be visualized in this radiograph below.

Look for the gas density (= black) in the CXR in the form of a balloon  (aligned vertically ) in the descending Ao.

In a CXR, patent alveoli = black ; atelectasis = white.

Other gas filled structures will also appear black :

> stomach, esophagus, ETT cuff.

> IABP (during inflation >> with Helium).
