Post-dive activities must not include going to altitude or areas of low pressure. While diving after flying is fine, flying soon after scuba diving is dangerous. If there is any excess nitrogen in your blood system, going into an area of low pressure will allow the nitrogen to escape into your tissues or joints.
How soon can you fly after diving?
For repetitive dives, or multiple days of diving a minimum preflight surface interval of at least 18 hours is recommended. DAN (Divers Alert Network) recommends 24 hours for repetitive dives, The US Air Force recommends 24 hours after any dive, while the US Navy tables recommend only 2 hours before flying to altitude.”

Can you go scuba diving after flying?
You can dive right after flying. There is a common misconception that, similar to needing time before you fly, you also need to wait after flying as well. The reason you shouldn’t fly right after diving is because of the nitrogen build-up in your body, but you won’t have that if you just got off a plane.
Can you get decompression sickness from flying?
Even if you are flying a pressurized aircraft, altitude DCS can occur as a result of sudden loss of cabin pressure (inflight rapid decompression). Following exposure to an inflight rapid decompressions do not fly for at least 24 hrs.
What causes divers to get the bends?
Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues.
Is there a cure for the bends?
The optimal treatment is the use of a hyperbaric oxygen chamber, which is a high-pressure chamber in which the patient receives 100% oxygen. This treatment reverses the pressure changes that allowed gas bubbles to form in the blood stream.
At what depth does the bends start?
The Bends/DCS in very simple terms
Anyone who dives deeper than 10 metres (30ft.) while breathing air from a scuba tank is affecting the balance of gases inside the tissues of their body. The deeper you dive, the greater the effect.
Can you talk while diving?
Scuba divers are trained to use hand signals to communicate with their buddies. They also use underwater writing boards, which allow for better communication. … The same system can be used for communication between the diver and a surface ship. Acoustic communication systems allow divers to talk to each other underwater.
What is the most common injury in scuba diving?
The most common injury in divers is ear barotrauma (Box 3-03). On descent, failure to equalize pressure changes within the middle ear space creates a pressure gradient across the eardrum.
What should you not eat before scuba diving?
The Week Before You Dive:
Remember any alcohol before your dive is a bad idea and dehydrates your system and makes you lose body warmth, a bad combination for diving. Make bread and starch and fruit be a big part of your diet.
Can you scuba dive every day?
Yes, you can scuba dive every day. As long as you remain with the dive table safety limits or use a dive computer. You have to monitor all your prior dives depth and bottom time, but 18-24 hours is plenty of time to recover between dives. You can even make several dives per day.
What does decompression sickness feel like?
The symptoms of decompression sickness vary, because the nitrogen bubbles can form in different parts of the body. The diver may complain of headache or vertigo, unusual tiredness, or fatigue. They may experience a rash, joint pain, tingling or a dull ache in the arms or legs, muscular weakness, or even paralysis.
How deep do you have to dive to get decompression sickness?
At depths greater than 40 metres (130 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed. In the event of an emergency, the diver cannot make an immediate ascent to the surface without risking decompression sickness.
Does decompression sickness go away?
However, In many cases of decompression illness the symptoms are only minor, such as: joint pain, numbness or tingling and muscular weakness. … Sometimes these symptoms remain mild and go away by themselves, however, they often continue to persist or even increase in severity and medical advice will need to be sought.
What is the treatment for decompression sickness?
All cases of decompression sickness should be treated initially with 100% oxygen until hyperbaric oxygen therapy (100% oxygen delivered in a high-pressure chamber) can be provided.
