In hypovolemic trauma patients with ongoing hemorrhage, the physical findings may lag behind the presentation of shock and cardiopulmonary collapse. Am J Emerg Med. Pneumothorax, especially tension pneumothorax is fatal; complications that can occur due to pneumothorax and tube thoracostomy are: Diagnosing and managing traumatic and iatrogenic pneumothoraces require multidisciplinary coordination and teamwork. Hypotension that worsens with inspiration Hypotension that worsens with inspiration is associated with tension pneumothorax due to compression of the heart and great vessels (obstructive shock). Fluorescein-enhanced autofluorescence thoracoscopy in patients with primary spontaneous pneumothorax and normal subjects. [31][32][33][34], Patients requiring surgical intervention are usually patients with bilateral pneumothoraces, recurrent ipsilateral pneumothoraces, first presentation in patients with high-risk professions like pilots and drivers, and patients with persistent air leaks (for more than seven days).
