Pulmonary barotrauma is a kind of disease caused by the injury of lung tissue or blood vessel when the gas pressure of lung is too high or too lower than the external pressure of the body, which causes the air to enter the blood vessel and adjacent tissue. It could be happened in the escape of the divers with the light diving equipment or the sailors from submarine. Generally, the decompression chamber was used to treating the disease, and the minimum air pressure of 0.5 MPa recompression therapeutic schedule was used to selecting. In November 2019, a patient with pulmonary barotrauma combined with cerebral arterial gas embolism caused by improper underwater escape with light diving equipment was admitted to the General Hospital of Eastern War Zone. He was treated with 0.12 MPa oxygen inhalation recompression scheme in the oxygen chamber pressurized with air. 7 days later, the patient recovered and discharged.
肺气压伤是指肺内压过高或过低于外界气压时造成肺组织和血管撕裂，以致气体进入血管和邻近组织而引起的包括一系列症状和体征的综合征，多见于使用轻潜水装具潜水逃生或潜艇艇员水下出艇，通常使用减压舱、选择不低于0.5 MPa（表压）加压治疗方案治疗。2019年11月东部战区总医院收治1例轻潜水装具作业、水底不当逃生引起的肺气压伤并发脑动脉气栓症患者，使用空气加压氧舱设备及0.12 MPa（表压）吸氧加压治疗方案，7 d后痊愈出院。.
