After the dive, you should do the following:
- Protect yourself from heat loss by wearing adequate clothing.
- Never try to carry out in-water decompression in the event of suspected decompression illness.
- Avoid exertion.
- Never underestimate the appearance, even if late, of any symptom following a dive and call Divers Alert Network (DAN) or emergency services to evaluate the situation.
- Avoid flying or driving to altitudes greater than 300 meters/1,000 feet after diving. Both of these actions take you to lower pressures, which can be dangerous if you have not allowed adequate surface intervals. Follow the DAN recommendations to wait at least 12 hours after a single no-stop dive and at least 24 hours after repetitive diving or decompression diving.
