All are true about Tension pneumothorax except?
Tension pneumothorax occurs mostly during Mechanical ventilation or Resuscitative effos The positive pressure is transmitted to mediastinum decreasing the venous return and cardiac output. A large bore needle should be inseed into pleural space through second intercostal space to allow air to escape. Needle aspiration using syringe is done for primary spontaneous pneumothorax Types of pneumothorax and primary management Primary spontaneous pneumothorax Simple needle aspiration followed by thoracoscopy with pleural abrasion. Secondary pneumothorax Tube thoracotomy followed by thoracostomy with stapling of blebs. Traumatic pneumothorax Supplemental oxygen or aspiration followed by tube thoracostomy. Tension pneumothorax Large bore needle in 2nd I/C space followed by tube thoracostomy.
Leading cause is mechanical ventilation.
Positive pressure in pleural space throughout the respiratory cycle.
Needle aspiration of air
Inadequate cardiac output.
