Answer

Pulse oximetry is mandatory in all children with suspected pneumomediastinum.

In a series of children with asthma presenting to an emergency department, those with pneumomediastinum had a significant difference in oxyhemoglobin saturation (90% vs 94% of those without pneumomediastinum, p = 0.03).
