What is the most common type of barotrauma?
Middle ear barotrauma (MEBT) is the most common being experienced by between 10% and 30% of divers and is due to insufficient equilibration of the middle ear. External ear barotrauma may occur on ascent if high pressure air is trapped in the external auditory canal either by tight fitting diving equipment or ear wax.
What is the most severe form of barotrauma?
The most serious form of ascent barotrauma is pulmonary injury. Additionally, injury to the lung from positive airway ventilation is a special case of barotrauma. The most serious consequence of barotrauma is a pulmonary alveolar rupture with antecedent air gas embolism.Jul 26, 2021
What is another name for barotrauma?

What type of hearing loss is barotrauma?
Ear barotrauma is a type of ear damage. It is caused by pressure differences between the inside of the ear and the outside of the ear. It can cause pain and sometimes lifelong (permanent) hearing loss. The middle ear is an air-filled space between the inner and outer parts of the ear.
What is an example of barotrauma?
The most common cause of pulmonary barotrauma is breath-holding during an ascent from a scuba dive, typically resulting from running out of air at depth. In panic, divers may forget to exhale freely as air in the lungs expands during the ascent.
What is lung barotrauma?
Barotrauma is tissue injury caused by a pressure-related change in body compartment gas volume. Factors increasing risk of pulmonary barotrauma include certain behaviors (eg, rapid ascent, breath-holding, breathing compressed air) and lung disorders (eg, COPD [chronic obstructive pulmonary disease]).
What causes pulmonary barotrauma?
Pulmonary barotrauma occurs from holding your breath during ascent, which allows pressure to rise in your lungs. The increase in pressure results in rupture. Air also may penetrate into the tissue around your lungs. The classic cause of an air embolism is rapidly ascending to the surface because of panic.Nov 13, 2020

What is buzzing in your ears?
Tinnitus is when you experience ringing or other noises in one or both of your ears. The noise you hear when you have tinnitus isn't caused by an external sound, and other people usually can't hear it. Tinnitus is a common problem. It affects about 15% to 20% of people, and is especially common in older adults.Feb 4, 2021
What is bilateral Tympanosclerosis?
Tympanosclerosis is a scarring process with a remarkable variability in its localization within the middle ear. It can lead to conductive hearing loss in many cases. It is usually caused by recurrent chronic inflammation of the middle ear.
How can barotrauma be avoided?
Barotrauma may be caused when diving, either from being crushed, or squeezed, on descent or by stretching and bursting on ascent; both can be avoided by equalising the pressures. A negative, unbalanced pressure is known as a squeeze, crushing eardrums, dry suit, lungs or mask inwards and can be equalised by putting air into the squeezed space. A positive unbalanced pressure expands internal spaces rupturing tissue and can be equalised by letting air out, for example by exhaling. Both may cause barotrauma. There are a variety of techniques depending on the affected area and whether the pressure inequality is a squeeze or an expansion:
What is the difference between barotrauma and MEBT?
Barotrauma can affect the external, middle, or inner ear. Middle ear barotrauma (MEBT) is the most common being experienced by between 10% and 30% of divers and is due to insufficient equilibration of the middle ear. External ear barotrauma may occur on ascent if high pressure air is trapped in the external auditory canal either by tight fitting diving equipment or ear wax. Inner ear barotrauma (IEBT), though much less common than MEBT, shares a similar mechanism. Mechanical trauma to the inner ear can lead to varying degrees of conductive and sensorineural hearing loss as well as vertigo. It is also common for conditions affecting the inner ear to result in auditory hypersensitivity.
What is a PBt?
This pulmonary barotrauma (PBt) of ascent is also known as pulmonary over-inflation syndrome (POIS), lung over-pressure injury (LOP) and burst lung. Consequent injuries may include arterial gas embolism, pneumothorax, mediastinal, interstitial and subcutaneous emphysemas, not usually all at the same time.
How does barotrauma affect the diver?
When diving, the pressure differences which cause the barotrauma are changes in hydrostatic pressure: There are two components to the surrounding pressure acting on the diver: the atmospheric pressure and the water pressure. A descent of 10 metres (33 feet) in water increases the ambient pressure by an amount approximately equal to the pressure of the atmosphere at sea level. So, a descent from the surface to 10 metres (33 feet) underwater results in a doubling of the pressure on the diver. This pressure change will reduce the volume of a gas filled space by half. Boyle's law describes the relationship between the volume of the gas space and the pressure in the gas.
What is the difference between explosive blast and explosive decompression?
The difference in pressure between internal organs and the outer surface of the body causes injuries to internal organs that contain gas, such as the lungs, gastrointestinal tract, and ear.
How to treat a diving barotrauma?
Lung over-pressure injury may require a chest drain to remove air from the pleura or mediastinum. Recompression with hyperbaric oxygen therapy is the definitive treatment for arterial gas embolism, as the raised pressure reduces bubble size, low inert gas partial pressure accelerates inert gas solution and high oxygen partial pressure helps oxygenate tissues compromised by the emboli. Care must be taken when recompressing to avoid a tension pneumothorax. Barotraumas that do not involve gas in the tissues are generally treated according to severity and symptoms for similar trauma from other causes.
What is a fish's bladder?
The swim bladder is an organ of buoyancy control which is filled with gas extracted from solution in the blood, and which is normally removed by the reverse process.
What is ear barotrauma?
Ear barotrauma is ear damage caused by a difference in pressure between the inside of the ear and the air around you. It can cause pain and may lead to lasting hearing loss. It may affect the outer, middle, or inner ear and can harm the eardrum. The eardrum is between the outer and middle ear. Harm to the eardrum can cause bleeding or other damage to the outer, middle, or inner ear.
How to prevent ear barotrauma?
If you are congested from a cold or allergies, you may want to delay flying or scuba diving. Or you can take medicine such as a decongestant or antihistamine. These may help your ears equalize more easily and prevent ear barotrauma.
How to do Valsalva maneuver?
To do this, you pinch your nostrils shut, close your mouth and gently force air into the back of your nose, as if you were blowing your nose.

Overview
Barotrauma is physical damage to body tissues caused by a difference in pressurebetween a gas space inside, or in contact with, the body, and the surrounding gas or fluid. The initial damage is usually due to over-stretching the tissues in tension or shear, either directly by expansion of the gas in the closed space or by pressure difference hydrostatically transmitted through the tissue…
Presentation
Examples of organs or tissues easily damaged by barotrauma are:
• Middle ear (barotitis or aerotitis)
• Paranasal sinuses (causing aerosinusitis)
• Lungs
• Eyes (the under-pressure air space is inside the diving mask )
Pathophysiology
Gas in the arterial system can be carried to the blood vessels of the brain and other vital organs. It typically causes transient embolism similar to thromboembolism but of shorter duration. Where damage occurs to the endothelium inflammation develops and symptoms resembling stroke may follow. The bubbles are generally distributed and of various sizes, and usually affect several areas, resulting in an unpredictable variety of neurological deficits. Venous gas can be admitted to the …

In terms of barotrauma the diagnostic workup for the affected individual would include the following:
Laboratory:
• Creatine kinase (CPK) level: Increases in CPK levels indicate tissue damage associated with decompression sickness.
