Abstract:
Objective:To establish a theoretical calculating method for real-time safe decompression scheme.Methods:Based on the Haldane theory, this research determined the assumed time unit, theoretical organization and classification, safety factor of nitrogen supersaturation and its selecting method, which were suitable for real-time safe decompression scheme calculation, and established a calculating method for real-time safe decompression scheme, then validated that calculating method by observing the behavioral change and detecting Doppler bubble sound with 112 sheep/times and 28 pressurization schemes.Results:There was no behavioral abnormality in all the animals after leaving cabin, and the results of Doppler blood bubble sound detection were zero level.Conclusion:The decompression scheme obtained by theoretical calculation was safe and reliable.
