12/12/2023 0 Comments Pulmonary barotrauma symptoms![]() ![]() Scientists estimate that the resistance of the lungs to the pressure difference is of the order of 0.2 to 0.3 bar which equates to a depth of 2 to 3 m. Pulmonary overpressure is therefore nothing more than an effect of excessive dilation of the lungs during the ascent to the surface during your dive. Pressure that divers encounter from the moment they go underwater.īy applying the simplified Boyle and Mariotte’s Law (Pressure X Volume = Constant), it is understandable that the air inspired deep will expand during the ascent to cause lung damage if it is not expired. In fact, if the lungs are magnificent organs that allow us to breathe throughout our lives, they are nevertheless very sensitive to pressure differences. Pulmonary overpressure is therefore the result of damage caused by an excessive pressure in the lungs. The pulmonary overpressure is classified in the diving accidents called barotrauma: baro (pressure) and trauma (damage to the body) If you want to know a little more about how it works and how to avoid it, here it is: You said pulmonary overpressure ? If you want to understand its mechanism in a few seconds (and not forget it), go to the bottom of this article to watch the video. This is why it is useful, important and essential to understand how pulmonary overpressure works when you want to practice scuba diving. The most serious diving accident, the pulmonary overpressure unfortunately almost always causes respiratory complications and often leads to death. Impossible to practice scuba diving without hearing about the pulmonary overpressure. ![]()
