A Log Logistic Survival Model Applied to Hypobaric Decompression Sickness

摘要: Decompression sickness (DCS) is a complex, multivariable problem. A mathematical description or model of the likelihood DCS requires large amount quality research data, ideas on how to define decompression dose using physical and physiological variables, an appropriate analytical approach. It also high-performance computer with specialized software. I have used published data develop my doses, which are variants equilibrium expressions for evolved gas plus other explanatory variables. My approach survival analysis, where time occurrence modeled. conclusions can be applied simple hypobaric decompressions - ascents lasting from 5 30 minutes and, after hours, denitrogenation (prebreathing). They applicable long short exposures, whether sufferer at rest exercising altitude. Ultimately would like models astronauts reduce risk during spacewalks, as well future spaceflight crews Moon Mars.
