Your question: Which part of the ear of a scuba diver is most likely to be damaged?

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.

Can diving damage your ears?

Ear barotrauma is by far the most common injury reported among divers. As explained above, the injury is typically a result of poor equalisation. However, diving with a cold can also lead to the injury. As pressure builds up inside the ear, it can cause your eardrums to bulge.

What happens to your ears when you scuba dive?

As divers descend down towards the bottom of the sea, the water pressure on their eardrums increases. This pressure against the eardrums causes the symptoms of ear squeeze. Starting with a feeling of fullness, it can become quickly very uncomfortable and dangerous as the eardrums swell and bulge.

Which part of the body can be damaged by barotrauma?

What are the risk in diving?

Diving does entail some risk. Not to frighten you, but these risks include decompression sickness (DCS, the “bends”), arterial air embolism, and of course drowning. There are also effects of diving, such as nitrogen narcosis, that can contribute to the cause of these problems.

Can I scuba dive if I have anxiety?

Whether it’s nervousness whilst completing your mask skills in your Open Water Course, anxiety when diving in a strong current for the first time, or a little discomfort when diving in lower visibility than you’re used to, it’s all perfectly okay – these are valid emotions to experience.

Why do ears hurt after diving?

Ear pain occurs during the descent portion of a dive as the diver drops deeper underwater. As the diver descends in the water, water pressure increases on the external surface of the ear drum (tympanic membrane). To counterbalance this pressure, the air pressure must reach the inner surface of the ear drum.

How do you dry your ears after diving?

Use either a commercial product designed to remove water from the ear canal ,or a mixture of half white vinegar and half rubbing alcohol after a diving excursion to gently clean and dry the ear canal.

How do you get rid of ear pain after diving?

Treatment

  2. Taking an over-the-counter (OTC) nasal decongestant, antihistamine, or both. …
  3. Stopping a diving descent at the first sign of ear discomfort to allow time for equalizing.

What happens if you don’t equalize while scuba diving?

However, if a diver does not equalize early or often enough, the pressure differential can force the soft tissues together, closing the ends of the tubes. Forcing air against these soft tissues just locks them shut. No air gets to the middle ears, which do not equalize, so barotrauma results.

What happens if your ears don’t pop after flying?

Your goal is to move the muscles of your mouth to open the airway. Swallowing and yawning (even fake yawning, with your mouth open wide) are the first things to try, and you can also chew gum or suck on candy.
