You want to avoid creating a relative vacuum (negative pressure) in the middle ear air-filled cavities. But, divers can also encounter a 'reverse squeeze' on the way back up to the surface.įactors that often create equalisation problems for scuba divers include: It happens most often during abrupt pressure changes, such as when descending. In most cases, this 'blockage' is likely to be a contributing factor for MEBT. In simple terms, any kind of obstruction in the eustachian tube reduces a diver's ability to achieve equalisation. So, why do some divers suffer this medical complication more than others? Health surveys suggest middle-ear barotrauma affects around 80% of divers at some time or another. But, failing to equalise the pressure in the air space of the middle ear with the surrounding pressure (ambient) is a frequent cause of MEBT - especially with inexperienced divers. No matter whether you're a beginner or a professional, equalizing pressure while diving is a fundamental part of the process. Whereas, the canals contribute some control over the way we balance and position ourselves. The cochlea converts soundwaves into electrical impulses for the brain. Note: The inner ear forms part of the central nervous system and has two main functions.
