▚ NITROGEN LEAVING TISSUES ▚
Off-gassing
The slow release of dissolved inert gas from body tissues as ambient pressure drops — during ascent, safety stops, surface intervals, and the hours after diving. Computers model it continuously; the no-fly clock exists because off-gassing keeps running long after you towel off.
▚ TRAINING NOTEDive within your training and certification. This is gear research, not dive instruction, and not a substitute for training from a certified instructor. Service intervals and no-fly figures cited on this site are illustrative — follow your manufacturer’s manual and your agency’s / DAN’s guidance.
