It is also classified under the broader term of dysbarism, which covers all medical conditions resulting from changes in ambient pressure. Decompression illness is a term that includes decompression sickness and arterial gas embolism caused by lung overexpansion barotrauma. However, these bubbles form out of supersaturated solution from dissolved gases, and are not generally considered barotrauma. Decompression sickness is indirectly caused by ambient pressure reduction, and tissue damage is caused directly and indirectly by gas bubbles. Tissue rupture may be complicated by the introduction of gas into the local tissue or circulation through the initial trauma site, which can cause blockage of circulation at distant sites or interfere with the normal function of an organ by its presence.īarotrauma generally manifests as sinus or middle ear effects, lung overpressure injuries and injuries resulting from external squeezes. The initial damage is usually due to over-stretching the tissues in tension or shear, either directly by an expansion of the gas in the closed space or by pressure difference hydrostatically transmitted through the tissue. Pressure difference between the environment and a gas-filled space in or in contact with the affected tissuesīarotrauma is physical damage to body tissues caused by a difference in pressure between a gas space inside, or contact with, the body and the surrounding gas or liquid.

Or, they may need to release the pressure or fluid with a small incision in your ear drum.Squeeze, decompression illness, lung overpressure injury, volutrauma They may recommend inserting small pressure equalization tubes or a balloon to help dilate your eustachian tubes. If your ears fail to open, or if you are experiencing persistent pain in your ears, seek the help of an ENT (ear, nose, and throat) specialist, or otolaryngologist. Extended use of decongestant nasal sprays can also cause more congestion than relief, and even result in a type of addiction. However, if you are pregnant, or have heart disease, high blood pressure, irregular heart rhythms, thyroid disease, or excessive nervousness, consult your physician before using these medications. Over-the-counter nasal sprays or decongestants can also help air travelers to shrink the membranes and help the ears pop more easily. If you have allergies, take your medications at the beginning of your flight.
You and your children should avoid sleeping during descent because swallowing may not occur often enough to keep up with changes in air pressure. Plus, babies cannot intentionally pop their ears, but sucking on a bottle or pacifier can help. You’ll know if it worked when you hear a pop, and your ears feel less plugged.īabies and children are especially vulnerable to ear blockage because their eustachian tubes are narrower than in adults. You can also try pinching your nose, taking a mouthful of air, blowing gently (not forcefully) against your pinched nose, then swallowing. Yawning, chewing gum, or sucking on hard candy can help, especially just before take-off and during descent. The simplest way to help clear your ears-particularly when flying-is to swallow.
