Headache may develop in flight passengers without underlying pathology even though this type of headache is not included in "The International Classification of Headache Disorders". We report on a case of headache which had developed during airplane landing. A rapid change in the ambient pressure may give rise to headache.

2.A case of pulmonary barotrauma complicated with cerebral arterial air embolism in a diver.
Chinese Journal of Industrial Hygiene and Occupational Diseases 2021;39(7):538-539
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.

A self-inflating bag resuscitator is universally used to ventilate patients during cardiopulmonary resuscitation and transfer. This device can be reused after sterilization and reassembly, and the mis-assembly of a resuscitator can possibly happen. We report here on a case of mis-assembly of a resuscitator valve that resulted to barotrauma and instability of a patient.

Malfunction of the unidirectional valve in a breathing circuit system may cause hypercapnia from the rebreathing of expired gas, ventilation failure, and barotrauma. Capnography is a useful method for monitoring the integrity of the unidirectional valve. We experienced two cases of malfunction of a unidirectional valve which caused leakage and reverse flow, diagnosed early as a change of the capnographic waveform. One case was caused by expiratory unidirectional valve breakage. The other was caused by an incorrectly-assembled inspiratory unidirectional valve.

5.Underwater and Hyperbaric Medicine as a Branch of Occupational and Environmental Medicine.
Annals of Occupational and Environmental Medicine 2013;25(1):39-
Exposure to the underwater environment for occupational or recreational purposes is increasing. As estimated, there are around 7 million divers active worldwide and 300,000 more divers in Korea. The underwater and hyperbaric environment presents a number of risks to the diver. Injuries from these hazards include barotrauma, decompression sickness, toxic effects of hyperbaric gases, drowning, hypothermia, and dangerous marine animals. For these reasons, primary care physicians should understand diving related injuries and assessment of fitness to dive. However, most Korean physicians are unfamiliar with underwater and hyperbaric medicine (UHM) in spite of scientific and practical values. From occupational and environmental medicine (OEM) specialist's perspective, we believe that UHM should be a branch of OEM because OEM is an area of medicine that deals with injuries caused by physical and biological hazards, clinical toxicology, occupational diseases, and assessment of fitness to work. To extend our knowledge about UHM, this article will review and update on UHM including barotrauma, decompression illness, toxicity of diving gases and fitness for diving.

6.Forensic Review of Underwater Diving-Related Death.
Korean Journal of Legal Medicine 2002;26(1):17-26
The popularity of SCUBA diving as aquatic sports is increasing in trend and therefore the risk of diving-related accidents or death is also increased. In underwater environment, with its rapidly changing ambient pressures, human body is subjected to pathophysiologic challenges. The common forms of medical problem with diving are barotrauma, decompression sickness and nitrogen narcosis, and the most common cause of diving-related death is drowning. However, the determination of the cause of death associated with diving should not be derived from the autopsy alone but must result from interpretation of data including a detailed history of the events prior to death, information about accident locus, diving suits, breathing apparatus and their accessories, and complete autopsy including toxicology and histological examination. And to explain the mechanism of death, the forensic pathologists should understand the diving physiology, law of gas physics and other diving hazards, and also be approached by the team effort involved by professional diver. Through the review of cases of SCUBA diving-related death and the literature, the author discuss the investigative approach to diving accidents and complete autopsy procedure with toxicological screen.

Pulmonary barotrauma during ascent is a common complication in SCUBA diving. One of the most severe forms of pulmonary barotrauma is a cerebral arterial gas embolism(CAGE). It is reported to account for about 30% of diving related deaths. The early recognition of CAGE is very important for the emergency physician because prompt hyperbaric recompression therapy can improve the clinical course. Thus, the emergency physician should know the clinical manifestation of CAGE to apply several treatment modalities early. We report a case of cerebral arterial gas embolism presented with hemiparesis and blurred vision immediately after SCUBA diving at 13 meters.

Colon barotrauma can be mostly caused by elevated intraluminal pressure. Air insufflation during colonoscopy procedure is the most common cause of iatrogenic colon barotrauma. Cat scratch colon can usually be seen in the mild type of colon barotrauma, and colon perforation can be seen in the severe type. We presently report a case of non-iatrogenic colon barotrauma caused by industrial compressed air. Multiple linear mucosal ulcers were noted in the recto-sigmoid colon, but the colon was not perforated. The patient was discharged without any further complications after conservative treatments.

High frequency jet ventilation (HFJV) has advantage for laryngomicrosurgery that the transit of a small airway tube through the surgical field causes much less interference with surgery. We experienced a case of tension pneumothorax during high frequency jet ventilation. The possible cause of barotrauma in this case was obstruction of gas escape. It is recommened that meticulous care is taken to ensure and adequate pathway for expiration when HFJV is used.
