Abstract:
A diving decompression procedure is a specific rule that divers should follow when they ascend and get out of water. It
comes from the decompression theory and algorithm and is designed for the prevention of decompression sickness. With the
， ，
development of diving technology and diving medicine the decompression procedures are constantly innovated and the new
，
decompression procedure can be used in diving practice after safety verification. In principle the safety verification of
，
decompression procedures should be conducted on animal experiments before human experiments and the risks of
，
decompression sickness and oxygen toxicity should be systematically assessed. However the assessment methods used in
， ， ，
different studies differ greatly thus it is urgent to establish a standard and universal verification system. Traditionally the risk
， ，
assessment of decompression sickness and oxygen toxicity is mainly carried out by observing the incidence detecting bubbles
，
theoretical calculation and lung functional test. Furthermore biochemical indicators are increasingly becoming important
， ，
supplements. Due to the special underwater environment the diving operation is prone to accidents. Therefore in addition to
，
verifying the safety of the new decompression procedure exploring its safety decompression limit is of great significance for the
formulation of emergency decompression procedures in emergency situations. The specific approach is to shorten the
decompression time and assess the safety until the critical time for detecting bubbles without the occurrence of decompression
， ，
sickness is found. Future studies should continue to optimize safety assessment methods explore sensitive biochemical markers
，
clarify species associations and improve verification efficiency and reliability of results.
