Tension Pneumothorax: Diagnosis and Treatment
Tension pneumothorax occurs when air pressure in the pleural space compresses the heart and vessels. Clinical signs include absent breath sounds, possible hypotension, tachycardia, and respiratory distress. Rapid accumulation can lead to tension physiology. Diagnosis is through stethoscope examination or ultrasound. Treatment involves needle decompression, typically in the mid-axillary or subclavian position, to relieve pressure and stabilize the patient.
