While reducing the risk of decompression sickness due to flight, we should also consider reducing unnecessary time delay before flight. On this basis, the Chinese standard "flight requirements for divers after diving" is formulated. The standard specifies the altitude of two flights (helicopter and passenger plane), different diving types and whether decompression sickness occurs, puts forward suggestions on the shortest ground interval before flight, and puts forward supplementary instructions and treatment suggestions for flight in emergency and response to decompression sickness during flight, At the same time, some points for attention are put forward.
