Fact Check: the Truth Behind the 'Man Screaming with No Lungs' Urban Legend
By Elena Rostova
In trauma centers, severe thoracic trauma immediately raises alarms regarding vocal capacity. When a penetrating chest wound or fractured rib causes a pulmonary laceration, atmospheric air enters the pleural space between the chest wall and the lung tissue. This condition, known as a pneumothorax, breaks the negative pressure vacuum that keeps the lung expanded.
If air continues entering the pleural cavity without escaping, it develops into a life-threatening tension pneumothorax. The affected lung collapses into a dense, non-functional mass of tissue. When this occurs bilaterally, both lungs collapse simultaneously.
From a forensic standpoint, the immediate casualty of bilateral collapse is vocal capacity. With the pulmonary tissue deflated, the diaphragm can contract, but it cannot move air upward through the glottis. Air rushes uselessly into the pleural space instead of crossing the vocal folds. The victim experiences rapid respiratory failure followed by mechanical asphyxiation. Rather than producing a cinematic scream, a person suffering total pulmonary deflation can emit only a faint, raspy wheeze or a soft clicking sound as the tongue and palate move in a dry, empty mouth.
