Pneumothorax
A collapsed lung — the one absolute contraindication to HBOT.
A pneumothorax is air trapped between the lung and chest wall, collapsing the lung. An untreated pneumothorax is the single absolute contraindication to hyperbaric therapy, because pressure changes can turn it into a life-threatening tension pneumothorax.
