What is recommended practice if a diver experiences ascent discomfort?

When a diver experiences ascent discomfort, controlling ascent speed and breathing deeply is the recommended practice. This approach acknowledges the physiological effects of ascent, such as expansion of gases due to decreasing pressure, which can lead to discomfort or pain in areas where gas is trapped, such as in the lungs, ears, or sinuses.

By maintaining a controlled ascent speed, the diver allows the body adequate time to adjust to the changes in pressure. This helps prevent rapid expansion of gas and minimizes the risk of barotrauma, a condition that can arise from too quick of an ascent. Additionally, deep, steady breathing can help equalize pressure in the body and can assist in reducing any discomfort associated with pressure changes.

Other approaches, such as descending immediately or ascending faster, would not address the issue safely and could exacerbate the discomfort or lead to injuries. Ignoring the discomfort is also not advisable, as it could lead to more serious complications if the underlying issue is not addressed. Therefore, controlling ascent speed and focusing on deep breathing are essential practices for ensuring the diver’s safety and comfort during ascent.
