It has undoubtedly considerably improved the prognosis of certain very common forms of this disease that formerly were regarded as invariably hopeless.From the clinical point of view, one may consider several types of artificial pneumothorax: total collapse (complete collapse, compression pneumothorax), incomplete collapse, selective collapse (hypotensive pneumothorax, partial pneumothorax, expansile pneumothorax), simultaneous bilateral pneumothorax, and alternating pneumothorax.
