Pneumopericardium vs. Pneumomediastinum

Pneumo...what?

Hemodynamically-stable, newborn. Resuscitated at birth. Where is the air? What would you do about it?

X-ray: Pneumomediastinum vs. Pneumopericardium

Look for the air crossing the midline between cardiac silhouette and diaphragm as the distinction between the two conditions. Of course, there are always some exceptions.

CXR: Dextroposition & Dextrocardia/Situs inversus

CXRs from 4 different patients with 4 different combinations:

CXR: Pneumomediastinum

Hemodynamically stable, premie (920g). 24 hrs old. Transferred from outside hospital. This is the first CXR at this institution. How would you treat this?

CXR: Pericardial effusion & ...after (partial) pericardiocentesis (Hydropneumopericardium)

EKG: Low Voltage Complexes & Lead Misplacement

Low voltage complexes. Cause of this is evident in the CXR below.

What is the P wave axis? What will be the diagnosis for the unusual P wave axis?

If unusual P wave axis were to be due to misplacement of leads, which leads were misplaced?

If certain leads were misplaced...what would be the QRS axis, if the misplaced leads were
