The<unk>  (EAD) is a way of approximating the decompression requirements of breathing gas mixtures that contain nitrogen and oxygen in different proportions to those in<unk> , known as nitrox. The<unk> , for a given nitrox mix and depth, is the depth of a dive when breathing<unk>  that would have the same partial pressure of nitrogen. So, for example, a gas mix containing 36% oxygen (EAN36) being used at has an EAD of .
