What is barotrauma?

Barotrauma is an injury or discomfort felt during a change in the pressure between the body body filled with air and the outer atmosphere. During the take -off or landing of the aircraft, it is most often experienced as pressure in the passenger's ears. Barotrauma is also commonly felt in the diver's ears when descending in the water. However, several areas such as ears, cavities and lungs are filled with air and, as a result, either expand or download to deal with more drastic or sudden atmospheric changes. However, a quick change can burst fine tissue.

This is one practical example of Boyle's law, which states that if the temperature remains the same, the gas volume is inversely proportional to absolute pressure. This intermediate and pressure relationship explains why when you fly on the plane, a closed half -full bottle of water will appear after the take -off after take -off and why the empty bottle is crushed. The bottle volume extends to take -off due to reduced air pressure that exists outside the bottle. On the contrary, with increasingThe pressure of the external air pressure reduces the volume of the empty bottle.

While barotrauma usually occurs in air passengers and divers, you are at risk on the fan if the machine draws too much air into the lungs. Also, those who discharge a weapon or standing near another type of explosive explosion can be influenced by a pressure wave.

Barotrauma is felt like simple cracking of the ears on flying or as a deadly rupture of the lungs when the diver diving too quickly to the surface. Symptoms include: pain or discomfort in the ear, cavity, face, teeth, vteastins or lungs; stuffy or full feeling in the ears; headache; nausea; and dizziness.

Simple measures can prevent or alleviate barotrauma. Those who experience pain should try to balance the pressure between the inner cavity and the outside. Passengers can yawn, swallow or chew rubber on the plane. During take -offAnd landing should treat or drink from a bottle. Divers often make valsalva maneuver to clean air pockets in the ears and mask. The Valsalva maneuver consists of a violent blowing of air over the nose while holding their nostrils closed. Divers also learn to climb slowly and rise not faster than their bubbles, to allow their lungs to slow down slowly.
