Treatment of Pneumomediastinum
Pneumomediastinum is rarely serious and will usually resolve on its own. Treatment is aimed at managing symptoms and any underlying cause.

Most people will spend at least 24 hours in a hospital for observation. Recommended treatments include:

bed rest
avoidance of physical activity
anti-anxiety medication
cough remedies
oxygen to aid breathing and encourage absorption of the trapped air
pain-relieving drugs

If a lung condition is contributing to pneumomediastinum, that condition will typically require treatment. Doctors may prescribe antibiotics for infections or breathing treatments for asthma, for example.

Spontaneous pneumomediastinum usually resolves without treatment, although it has been known to persist for over 2 months in some cases.
