What additional checklist items do you need to follow when planning and preparing for deco dives?
What is the only real way to reduce the impact of nitrogen at depth?
Key Points to Remember
When planning and preparing for deco dives, you generally want to follow all the pre-dive checklist items covered in xTek Basics and Rescue, plus: generate any necessary dive tables; ensure cylinders are filled with the correct gas mixtures and are properly labeled; and, ensure that your computers are set for the correct FO2/PO2 values.
While building experience slowly while gradually increasing depth may help divers in dealing with narcosis, the only real way to reduce the impact of nitrogen at depth is to add helium to your breathing mixture.
