Physical Check-up of Scuba Diver and Decompression Illness

Abstract

 Because scuba diving is special activity to be carried out under the high pressure environment of undersea, a health appropriate standard becomes special. In Japan, there is a medical check/guideline prepared by Japanese Society of Hyperbaric and Undersea Medicine based on the Recreational Scuba Training Council which is the global diving standard for divers. Diver examination items are individually determined depending on whether these guidelines are met. First, the diver fills in a health questionnaire, and if there is no corresponding item, it will be only a general checkup, but if there is, it will decide additional examination items with reference to the guideline. In this thesis explain only diseases and pathological conditions that are not a problem in health conditions in general sports bring about serious obstacles in submergence activities, and that clinicians are likely to mislead excerpts and explains. In nervous system diseases, pathologies that can cause consciousness disturbances and fainting attacks are submission contraindications. Epilepsy is especially dangerous in fatal accidents. In the cardiovascular system, 9 METS exercise capacity is required, no cardiac shunt, high blood pressure is well controlled only with designated drugs. In the digestive system, diseases that can potentially because vomiting are drinking contraindications. In the respiratory system, there is no lung cavitary lesion, control of asthma is controlled by meeting the guidelines, and no history of pneumothorax. With blood disorders, diving cannot be performed in bleeding tendencies and pathological conditions with high blood cohesion. In the endocrine system, diabetes is impossible to dive in a condition requiring medication.

 In addition, knowing the decompression illness, which is a specific disease under the high-pressure environment, helps divers to check and diagnose. This includes a decompression sickness and an arterial gas embolism, which is a special disease that develops during depressurization during levitation.
