What is Pneumothorax?
This means that air has managed to seep into the pleural space, and as a result the lung is not expanding normally with breathing. It is not common with children, although it sometimes occurs with newborn babies. In this case it is a surgical emergency usually dealt with on the spot by doctors as breathing difficulty and blueness can be present.
Sometimes it occurs in older children from a variety of causes, maybe as a complication of some other lung disease, or even a foreign object in the lung that works its way to the lung surface, allowing air to escape. Most cases are mild as the air is reabsorbed and the child recovers, but, as we have said before, in any situation where there is any breathing difficulty, prompt medical care is essential.
