Is pneumopericardium life threatening?
In some cases, pneumopericardium can lead to a life-threatening complication called cardiac tamponade in which extra air builds up around your heart. The air puts pressure on your heart and stops it from working properly. Symptoms come on fast and include: Swelling in your arms and legs.
Is pneumopericardium an air leak?

¿Qué es el neumomediastino espontáneo?
El neumomediastino espontáneo es visto mayormente en hombres jóvenes [5,28-30]. El síntoma más común es el dolor torácico [30-34]. El presente estudio mostró que el dolor torácico fue visto en 26 de 36 pacientes (72%).
¿Cuál es el pronóstico del neumomediastino?
El pronóstico depende de la enfermedad o eventos que ocasionaron el neumomediastino. El aire se puede acumular y entrar al espacio alrededor de los pulmones (espacio pleural), haciendo que el pulmón colapse. En pocas ocasiones, el aire puede entrar en la zona entre el corazón y el saco delgado que rodea este órgano.
¿Cuál es el mecanismo de lesión más común en los pacientes con neumomediastino?
El mecanismo más común de lesión, en los pacientes con neumomediastino, es el trauma cerrado, con la prevalencia más alta en los pacientes involucrados en AVM de alta velocidad [9,12]. En un estudio de 136 pacientes con neumomediastino en un centro e trauma de nivel 1, el mecanismo de lesión en la mayoría de los pacientes (58%) fue el AVM [13].
