Answer Choices:
Absence of breath sounds
🤕Pneumothorax occurs when air enters the pleural space, preventing lung expansion and causing the lung to collapse.
👂Absent breath sounds on auscultation over the affected side indicate no air movement through the collapsed lung tissue.
📉The presence of air in the pleural space increases intrapleural pressure, further inhibiting ventilation in that area and thus eliminating breath sounds.
⚠️Identifying absence of breath sounds promptly is critical as a tension pneumothorax can rapidly compromise cardiovascular function.
📌Core Message
Air in the pleural space leads to lung collapse and absence of breath sounds.
