Pneumotórax hipertensivo ocorre quando a pressão intrapleural é superior à atmosférica em toda a expiração e frequentemente também também durante a inspiração. O mecanismo responsável pelo pneumotórax hipertensivo é a ruptura da pleura visceral ou parietal de tal forma que uma válvula unidirecional se desenvolve. Um pneumotórax hipertensivo pode ocorrer após qualquer tipo de pneumotórax; é independentemente da sua etiologia. Algumas vezes pode ocorrer após um pneumotórax espontâneo, mas é mais comum após um pneumotórax traumático, com ventilação mecânica ou durante ressuscitação cardiopulmonar. | |||
