How do patients with tension pneumothorax typically present?

Patients with tension pneumothorax generally present with hypotension and absent breath sounds due to the accumulation of air in the pleural space, which leads to increased intrathoracic pressure. This rising pressure effectively collapses the lung on the affected side, resulting in diminished or absent breath sounds on auscultation. Furthermore, as the pressure compresses the heart and great vessels, it can lead to decreased venous return, causing hypotension. These findings are critical, as tension pneumothorax is a life-threatening condition that requires immediate intervention.

The accompanying signs and symptoms, such as tachycardia, hypoxia, and respiratory distress, are also common, but hypotension and absent breath sounds are particularly indicative of this condition. Understanding the clinical presentation of tension pneumothorax is vital for timely diagnosis and management in emergency situations.
