Which of these statements correctly reflects a risk during ascent in diving?

Rapid ascent can indeed lead to barotrauma, which occurs when there is a rapid change in pressure that the body cannot equalize quickly enough. During ascent, the pressure decreases, and if a diver ascends too quickly, the gases dissolved in the body's tissues, especially nitrogen, expand rapidly. This rapid expansion can result in injury to various tissues, particularly in areas like the lungs and ears, where the pressure changes are most significant.

Understanding this risk underscores the importance of a controlled ascent rate, typically no faster than 30 feet per minute, and the necessity of making safety stops to allow the body adequate time to eliminate excess nitrogen safely. It highlights the need for divers to be educated about proper ascent techniques, dive tables, and personal limits to minimize the risk of barotrauma and other decompression-related issues.
