Based on dive profile, conditions and how you feel, discuss your options with your buddy, and if you are still without symptoms after a minute or two, consider descending to complete your safety stop.
If you experience any symptoms after a too rapid ascent, it is important to seek a qualified medical evaluation, as well as first-aid care if necessary. For more information on safe diving practices, visit DAN. Being hydrated lessens the risk of getting the bends. Always drink plenty when before your dive. Make sure to read this article about the decompression sickness risk factors.
You should never mix alcohol and scuba diving. Even drinking the night before and diving on a hangover could affect you. You must leave at least 24 hours between your last dive and when you fly. This avoids the risk of getting the bends on the flight. More Reading : How long should you wait to fly after diving? Many scuba divers with a hole in the heart or a septal defect can be susceptible to unexpected decompression sickness. Get this checked out at your local GP or hospital. In the vent of a fast ascent oxygen is a must have resource for immediate administration to the casualty.
Oxygen lessons the effects of decompression sickness. If your dive includes decompression stops make sure you carry out adequate planning for these stops. Plan for the extra air consumption needed for each decompression stop. Make sure to take account of how air is consumed faster the deeper you go.

Diving within your certification level and experience will avoid any decompression problems. Learn to control your buoyancy to control your ascent rate.
Always ascending slowly from a dive will avoid any risk of decompression sickness. Adhere to safety stops on every dive you do. Carry out decompression stops when required on decompression-stop dives. Make sure you have enough air for your deco-stops when you leave for the surface. Avoid yo-yo diving profiles. Always dive with a buddy who should have an alternative air source. An exhilarating sport, deep-water diving is made even more exciting by the frisson of danger.
Certified divers take extra courses to receive deep-water dive certification -- and that training includes a thorough grounding in the risks and safety procedures for descending and ascending to avoid uncomfortable or dangerous reactions to the changes in pressure.
When you do come up too fast from a deep dive, you can experience decompression sickness -- DCS -- commonly called "the bends. A deep-water dive involves depths of 60 to feet, according to PADI, the Professional Association of Diving Instructors, the agency that dominates worldwide scuba certification.
For a recreational diver, this usually means a wreck dive or a bounce dive -- a dive to the bottom or deepest depth with the fastest possible return to the surface. Bounce dives are supposed to minimize the pressure problems you can encounter in deep-water dives but they still carry a degree of risk. Deep diving places more stress on your body than shallow diving due to pressure differences and colder water temperatures.
Pressure differences pose the greatest health risks, and it helps to understand why. There are three kinds of injuries from pressure changes when diving: Barotrauma: Tissues near the air-filled spaces of your body—such as your ears, sinuses, dental roots, and lungs—can be damaged if your body can't equalize the pressure between it and the surrounding water.
This kind of injury is called barotrauma. As you descend, water pressure increases, and the volume of air in your body decreases. This can cause problems such as sinus pain or a ruptured eardrum. As you ascend, water pressure decreases, and the air in your lungs expands. This can make the air sacs in your lungs rupture and make it hard for you to breathe.
If air bubbles get into an artery, they can cause a blockage that affects your organs. The blockage is called an arterial gas embolism. Depending on where the bubbles are, you could have a heart attack or a stroke. 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. This doesn't cause a problem when a diver is down in the water. And if a diver rises to the surface decompresses at the right rate, the nitrogen can slowly and safely leave the body through the lungs.
But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage. In extreme cases, it can cause paralysis or death if the bubbles are in the brain.
Nitrogen narcosis: Deep dives can cause so much nitrogen to build up in the brain that you can become confused and act as though you've been drinking alcohol. You might make poor decisions, such as taking out your regulator because you think you can breathe underwater. Narcosis usually happens only on dives of more than feet.
