I have been on about 20 dives past 100 on air. Deepest was 143. I felt no symptoms. We performed some short tasks at depth that involved securing a shotline weight at the bottom the existing support/weight. We spent 1.5 minutes at depth. By our assessments we were not impaired in any way. We performed the tasks; tying a prussik loop and strobe to the shot line etc. Is there any study that has empirical data showing how much time and uptake causes symptoms ? I have been unable to find specific scientific data anywhere. I know it apparently varies from person to person but I would have expected to feel very noticeable symptoms. Also looking to hear from others who have experienced Narcosis. How severe were the symptoms? What depth and bottom time ?
