Aerosinusitis. Paranasal sinuses. Aerosinusitis, also called barosinusitis, sinus squeeze or sinus barotrauma is a painful inflammation and sometimes bleeding of the membrane of the paranasal sinus cavities, normally the frontal sinus. It is caused by a difference in air pressures inside and outside the cavities. [1][2][3][4][5]
Barotrauma is physical damage to body tissues caused by a difference in pressure between a gas space inside, or in contact with, the body and the surrounding gas or liquid. [1] [2] 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 ...
Barodontalgia, commonly known as tooth squeeze, is a pain in a tooth caused by a change in ambient pressure. The pain usually ceases at return to the original pressure. [1][2][3] Dental barotrauma is a condition in which such changes in ambient pressure cause damage to the dentition.
Decompression sickness (DCS; also called divers' disease, the bends, aerobullosis, and caisson disease) is a medical condition caused by dissolved gases emerging from solution as bubbles inside the body tissues during decompression. DCS most commonly occurs during or soon after a decompression ascent from underwater diving, but can also result ...
To avoid barotrauma, the diver equalises the pressure in all air spaces with the surrounding water pressure when changing depth. The middle ear and sinus are equalised using one or more of several techniques, which is referred to as clearing the ears. [5] The scuba mask (half-mask) is equalised during descent by periodically exhaling through ...
Nevertheless, barotrauma occurs and can be life-threatening, and procedures for first aid and further treatment are an important part of diving medicine. Barodontalgia. Barotraumas of descent (squeezes) Ear squeeze (also alternobaric vertigo) Sinus squeeze (aerosinusitis) Tooth squeeze (dental barotrauma, barodontalgia) Mask squeeze; Helmet squeeze
Ear clearing. Ear clearing, clearing the ears or equalization is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure.
Baroreceptor. Baroreceptors (or archaically, pressoreceptors) are sensors located in the carotid sinus (at the bifurcation of common carotid artery into external and internal carotids) and in the aortic arch. [1] They sense the blood pressure and relay the information to the brain, so that a proper blood pressure can be maintained.
