Why shouldn’t divers move up to the surface of the water after a deep dive?
“The bends” are even scarier. As you come to the surface from a dive, nitrogen gas can bubble up in your body like carbonation in a freshly opened can of soda. If you swim up too fast, decreasing pressure makes the bubbles expand, which can cause severe pain in your joints and create other problems in your body.
Why can I not equalize when diving?
You’ve descended to 10 feet when the pain in your ears starts. No matter what you do, you can’t equalize them. … Why It Happens: Divers need to equalize the “dead air” spaces in their middle ears, which are connected to the outer ears by eustachian tubes that run to the back of the throat.
What happens if you decompress too quickly?
If a diver ascends too quickly, the nitrogen gas in his body will expand at such a rate that he is unable to eliminate it efficiently, and the nitrogen will form small bubbles in his tissues. This is known as decompression sickness, and can be very painful, lead to tissue death, and even be life threatening.
What happens if a diver goes too deep?
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. … Narcosis usually happens only on dives of more than 100 feet.
Can you fart while diving?
Farting is possible while scuba diving but not advisable because: … An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness. The acoustic wave of the underwater fart explosion can disorient your fellow divers.

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.
