You asked: What is equalization in diving?

What is the purpose of equalization in diving?

To restore volume lost to pressure, you send air into the middle ear via the eustachian tubes, equalizing or “popping” your ears. Failing to do this causes ears to hurt when diving, and potentially damages the delicate mechanisms of the ear.

What happens if you don’t equalize when 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.

Is holding your nose and blowing bad for your ears?

Pop Your Ears by Holding Your Nose

Lightly blow out against the pressure. This should make your ears pop. The pressure you’re blowing against forces your Eustachian tubes open a little which drains pressure and fluid stuck in your ear. It’s a common misconception that this method is dangerous.

At what depth do you need to equalize?

A diver needs to equalize approximately every two to three feet (1 m). Doing so is particularly important in the first 15 to 30 feet (5 to 10 m) of the dive. This is when the largest proportional pressure change takes place. The art of equalizing ear and sinus cavities is to do it early and often.

What happens when you don’t equalize?

When you go deep enough and you don’t equalize, you will have a little puncture in your eardrum. What results to water in your inner ear and reach your balance organ. The balance organ controls your balance, so when water hits your balance organ your world will be upside down.

Is it bad to have your ears underwater?

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.

How do I know I am properly weighted for diving?

If you’re properly weighted, you should hover with the water’s surface at or slightly above eye level, with your forehead brushing the surface. Demonstrate negative buoyancy by sinking past eye level as you exhale. If you can easily descend when exhaling, fin back to the surface and establish positive buoyancy.

What to do if you can’t equalize your ears?

Altitude changes. Yawning or swallowing can help to open your eustachian tubes and equalize pressure. You may also consider using an over-the-counter (OTC) decongestant nasal spray. However, you should avoid using decongestants in young children.

Are humans neutrally buoyant?

What Is The Freefall? We are positively buoyant at the surface, and add weights to make ourselves neutrally buoyant at around 10-15m (32-49ft) since most shallow water blackouts occur between 10m (32ft) and the surface; this is a safety concept.
