To decompress and off gas excess inert gas correctly and efficiently is imperative so as to avoid decompression illness (DCI). By following the staged decompression procedures outlined here, your ability to off gas sufficiently increases and makes decompression diving safer. Remember, however, that no matter how stringent you follow decompression guidelines and safety factors, you can still be susceptible to getting DCI on any dive.
· Make sure you and your team hydrates well prior to the dive. Start hydration at least 12 hours prior to the dive and make sure to hydrate after the dive.
· Plan your dive appropriately with the right gases for your bottom mix and your decompression mixes. Use gases that limit inert gas buildup and allow for the best and most efficient off gassing during decompression.
· Locate, set up, and mark a point that provides the entire dive team a suitable place to decompress. This might include a down line when wreck diving or specific location in a cave or cavern when cave diving. You should be able to rest comfortably with some type of handhold so that your chest remains at a constant depth. You don’t want to be moving up and down. Sometimes knowing exactly where you’re going to decompress at each stop depth is not practical, but knowing the requirements you need to follow when at a stop depth can help you decide on a spot during the dive.
