Should you accidentally exceed your dive computer’s no decompression limit SDI?
Activities that may increase the risk of decompression sickness include: … Should you accidentally exceed your dive computer’s no-decompression limit. Air permitting, make the decompression stop indicated by your dive computer. Afterward, monitor for signs and symptoms of decompression sickness.
Should you accidentally exceed your dive computer’s no decompression limit quizlet?
If you exceed your no decompression limit or adjusted no decrompression limit by more than 5 minutes when using the RDP, you should: slowly ascend to 5 meters/15 feet and make a stop for at least 15 minutes, air supply permitting, then not dive for at least 24 hours.
What happens if you exceed no decompression limit?
Emergency Decompression: “If a no decompression limit is exceeded by no more than 5 minutes, an 8 minute decompression stop at 5m is mandatory. Upon surfacing, the diver must remain out of the water for at least 6 hours prior to making another dive.
What do I do if I exceed my computers no stop limits?
If you exceed a no stop limit, you will have to make an emergency decompression stop. You computer will go into decompression mode and guide you by providing the depth of your emergency decompression stop and how long you have to stay there before you can ascend to the surface.
What happens if a diver does not decompress?
If you don’t decompress when scuba diving you will end up with decompression sickness, which can be fatal. All dives are decompression dives, which means you should always ascend slowly after a dive and where appropriate carry out decompression stops. As a safety precaution you should also perform a safety stop too.
What should I do if my dive computer fails?
If the computer malfunctions, and you are only diving an NDL (No Decompression Limit) profile, and you know that you are well within your NDL, simply abort the dive. Even though your dive buddy may be wearing a dive computer, there is no way of being sure that your profile was the same as his.
What should you and your body do if separated during a dive?
The quick answer if you get separated from your dive buddy during a dive, is to stop and do a slow visual 360-degree spin. In doing so always remember to look up and down too. Look for telltale signs like your buddy’s bubbles or any disturbance of silt or sand on the bottom.
Why should I not turn off a dive computer between dives?
Don’t turn your computer off between dives.
Most won’t let you, but if you take out the battery or shut the computer down, it loses its memory of your previous dives and your residual nitrogen. You’ll have to allow all residual nitrogen to leave your body before resuming use of the computer.

What happens if you exceed NDL?
Longer time over the NDL may require an additional stop. If you miss a “deco” stop, your dive computer will go into a violation mode. It will still provide recommended stops, however, it will not start a new dive for 24 hours. Both you and your dive buddy must monitor your air consumption.
What is the no-decompression limit for a dive to 20 feet?
No Decompression Limits (NDL)
|10 m/33 ft.||2 bar/ata||21%|
|20 m/66 ft.||3 bar/ata||21%|
|30 m/99 ft.||4 bar/ata||21%|
|40 m/132 ft.||5 bar/ata||21%|
How deep can you dive without decompression stops?
