What is a common complication of prolonged CPR?

Prolonged CPR can lead to a pneumothorax, which is the presence of air in the pleural space that can cause the lung to collapse. During chest compressions, particularly if they are performed with excessive force or improper technique, there is a risk of damaging the lungs or ribs. This trauma can result in air escaping from the lung tissue and entering the pleural cavity, leading to a pneumothorax. Recognizing this complication is important for medical responders, as it may necessitate further medical intervention after the resuscitation process, such as the placement of a chest tube to relieve the pressure and allow the lung to re-inflate. Understanding the risk of pneumothorax emphasizes the need for careful technique during CPR to minimize potential adverse effects on the patient.
