Which method should be used for dives requiring in-water decompression on oxygen?

In-water decompression on oxygen involves specific protocols to minimize the risk of decompression sickness while ensuring safety during the ascent. Following an in-water air decompression schedule is critical for managing the dive safely. This method allows divers to ascend while utilizing the benefits of oxygen to help alleviate nitrogen loading, thus enhancing the decompression process.

Using air schedules is not appropriate in this context because air is not optimized for decompression when divers are using oxygen for in-water procedures. Similarly, while there are established recommendations for oxygen, they may not specifically address in-water decompression protocols, making them less applicable to this scenario.

Decompressing fully before surfacing also does not pertain to the practice of in-water oxygen decompression, as the entire point of the in-water procedure is to manage ascent during the dive rather than staying submerged until fully decompressed. Hence, following the in-water air decompression schedule ensures the safest and most effective approach to managing nitrogen and oxygen levels in the body during the ascent.
