As a follow-up to my previous article, ‘A Logical Application of Gradient Factors Settings for Open-Circuit Tech Divers<\/a>‘, I have decided to write a comparative case study that illustrates the effect that three different gradient factor settings can have on the dynamics of the dive.<\/p>\n\n\n\n Disclaimer:<\/strong>\u00a0 Any opinions provided in this article only reflect my own successful approach to decompression using gradient factors. Dives requiring staged decompression are substantially more risky than dives that stay well within no-stop limits. No strategy can guarantee to protect every diver from DCS<\/a> injury. Consequently, I reserve liability for any decisions you may make. Never risk your life on only one source of information. If you choose to make riskier dives, obtain the proper training and work up to them slowly to gain experience.<\/em><\/p>\n\n\n\n For this case study, I have used Multideco<\/a> software running ZHL-16C to plan an open-circuit 18\/45 trimix dive to a depth of 60m for 20 minutes. The dive utilized a single deco mix of 50%, with a gas switch conducted at the MOD of 21m.<\/p>\n\n\n\n
