Oxygen Toxicity and Special Operations Forces Diving: Hidden and Dangerous

In Special Operations Forces (SOF) closed-circuit rebreathers with 100% oxygen are commonly utilised for covert diving operations. Exposure to high partial pressures of oxygen (PO2) could cause damage to the central nervous system and pulmonary system. Longer exposure time and higher PO2 leads to faster development of more serious pathology. Exposure to a PO2 above 1.4 ATA can cause central nervous system toxicity, leading to a wide range of...
