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.
Who should not scuba dive?
“If you can reach an exercise intensity of 13 METS (the exertion equivalent of running a 7.5-minute mile), your heart is strong enough for most any exertion,” he says. You also need to be symptom-free. If you have chest pain, lightheadedness or breathlessness during exertion, you should not be diving.
What should you never do while scuba diving?
Never hold your breath while ascending. Your ascent should be slow and your breathing should be normal. Never panic under water. If you become confused or afraid during a dive, stop, try to relax, and think through the problem.
Do sharks mess with scuba divers?
Yes, sharks do attack divers, whether provoked or unprovoked. However, attacks are extremely rare, as sharks do not view scuba divers as a particularly appetizing prey. As such, diving with sharks cannot be considered a dangerous activity, although like everything in life some risks always exist.

What is the golden rule of scuba diving?
1. Never hold your breath. This is undoubtedly by far the most crucial of all safety rules for diving because failure to adhere could result in fatality.

What is the number one rule of scuba diving?
1. Breathe continuously while on scuba. Never hold your breath. There is no way, you would have missed that one.
Why do I need to pee after scuba diving?
As the level of ADH decreases the kidneys produce more urine. As I’ve explained, the production of urine is increased during most dives due to immersion and cold, resulting in dehydration after the dive and increasing the risk of DCS.
Can you cough while scuba diving?
It’s perfectly alright to cough into your regulator until your airway is clear. If you feel that telltale tickle in the back of your throat, try to move into an open area where you won’t bump into anything. Also, be aware of your buoyancy when coughing while scuba diving, as you may unknowingly hold your breath.
What happens if you inhale water while diving?
Once the lungs have inhaled water, this can damage the lung sacs and lead to swelling, which in turn, can disrupt the exchange of oxygen and carbon dioxide, and lead to respiratory distress syndrome hours later. If not treated, it could be fatal.
Can your lungs collapse from scuba diving?
In divers, the normal pressure build-up that occurs during ascents can cause the blebs to rupture. Blebs are likely caused by degradation of elastic fibers in the lung and are hard to detect. There are generally no signs or symptoms until they rupture.
What happens if you vomit while diving?
The vomit will be forced out the regulator in the same way your exhaled breath is. Nothing will get into your air supply because air does not flow back into your cylinder. Inhale carefully so you don’t suck food particles into your throat.
Why you should never hold your breath while diving?
If you hold your breath and the pressure surrounding you decreases, (i.e., you ascend) the air in your lungs will expand. When the air cannot escape in a natural way, the pressure in the lungs increases and a DCI results. Overexpansion of the lung can lead to serious injuries.
Should you close your eyes when diving?
If you are new to diving and wear contacts, it is important to note that you must keep your eyes closed during any skills that require you to flood or remove your mask.

What is the safest depth to dive?
The American Red Cross recommends a minimum of 9 feet of water depth for head first dives including dives from pool decks. Results for a comprehensive study of diving injuries are presented in “Diving Injuries: The Etiology of 486 Case Studies with Recommendations for Needed Action” edited by Dr.
Can you dive with anxiety?
Depending on divers’ motivations for continuing to dive and their willingness to work toward a resolution of their anxieties, there are psychological techniques that can be useful in overcoming these problems. Mild anxiety does not have to be a contraindication to recreational diving.
