T70: Effects of air pressure and water pressure

T70.9: Effect of air pressure and water pressure, unspecified

There is a certain pressure in every environment. The pressure in the air is atmospheric pressure and decreases with increasing altitude. The pressure in water is water pressure and increases with depth.

For example, the ambient pressure changes when changing altitude or while diving. There are various air-filled cavities in the body that constantly adjust to the ambient pressure.

If the ambient pressure suddenly changes, then sometimes the pressure in the body’s air-filled cavities may not adjust as quickly. Air-filled cavities in the body include the ears, nasal sinuses, lungs, and intestines.
