The Year of the Pig is about to arrive. The wanderer who has been busy for a year is going home. Some people choose to take a bus. Some people choose to take the train. Some people choose to take the high-speed rail. Some people choose to drive by themselves. Some people choose to fly. If you choose to fly, we have to Know in advance how to protect your own ears during flight?

Why do you need to protect your own ears when you are flying?

When living on land, our body has adapted to the pressure in this environment, does not feel uncomfortable, and will not be harmed by air pressure. However, when you get on the plane, take off to the sky or land from the sky to the ground, as the altitude changes, the surrounding air pressure constantly changes, which makes us feel the ears are up, pain, tinnitus, and even lead to otitis media and hearing. decline. Therefore, when flying, you need to learn to protect your own ears and avoid the occurrence of barotrauma otitis media.

What is barotrauma otitis media?

In flight, because the eustachian tube ventilation function fails to adapt to the sudden changes in environmental pressure, resulting in middle ear damage, this phenomenon is called “barotrauma otitis media or aeronautical otitis media.”

Yes, the key physiological part of this trauma is the Eustachian tube. In the normal condition of the ear tympanic membrane, the eustachian tube is the only structure that can ventilate the middle ear and balance the air pressure inside and outside. Maintaining the normal ventilation of the eustachian tube during flight is an important step to protect the ear.

How do passengers prevent ear pressure trauma during flight?

First, after taking off from the aircraft, until the beginning of a smooth flight in the high altitude, passengers can chew gum, diet, yawn, etc. These actions can open the eustachian tube; air pressure trauma usually occurs at this stage;

Secondly, when the plane begins to descend until the ground falls smoothly, the passengers need to do chewing gum, eating, yawning, etc.; if the eustachian tube can not open smoothly, the ear will feel numb and even pain, then each need Drop 305 meters and make an “Eustachian tube blowing method” (close your mouth, pinch your nose and swallow); air pressure trauma usually occurs at this stage, be careful!

Thirdly, if the eustachian tube malfunctions due to a cold or other upper respiratory tract infection, it is often expressed as “early suffocation when infected, hearing loss; hearing recovery after hearing recovery, ear suffocation disappears”; It is generally recommended that 2 will only start flying after the recovery.

Finally, if the nose and pharyngeal deformity or disease can interfere with the eustachian tube ventilation, affecting the middle ear to quickly balance the air pressure; such problems need to be corrected or treated to ensure that the Eustachian tube can be properly ventilated.

Tips:

After 1. The aircraft is flying smoothly, the Eustachian tube adapts to the air pressure and can be ventilated normally.

2. If you breathe in pure oxygen during flight, it is prone to slow-type air pressure damage after landing; to avoid this, wear a mask to absorb 3/4 lung vitality, then remove the mask and then absorb 1/4 lung vitality air. can.

3. If there is air pressure regulating equipment in the aircraft cabin and it is in normal use, there is no need to operate the above several precautions;

4. Anyone with eustachian tube dysfunction should not be engaged in aviation work, such as pilots, air service personnel, etc.; the hearing center of a large hospital can test whether the eustachian tube function is normal;
