What can happen if decompression tables are not followed when ascending?

Following decompression tables is crucial for ensuring a safe ascent after diving. When these tables are not adhered to, the risk of decompression illness significantly increases. This medical condition occurs when a diver ascends too quickly, leading to the formation of nitrogen bubbles in the bloodstream and tissues. The rapid reduction in pressure while ascending can cause these gases, which have been absorbed at higher pressure during the dive, to come out of solution too quickly. This can result in various symptoms ranging from mild joint pain to more severe neurological issues and even life-threatening conditions.

While the other choices may seem unrelated or beneficial in a diving context, they do not accurately represent the consequences of improperly ascending without following decompression procedures. Understanding the importance of slow ascents and adhering to established dive tables is essential for ensuring safety and preventing decompression sickness.
