What acronym is used to remember signs and symptoms of oxygen toxicity?

The acronym "ConVENTID" is specifically designed to help divers recall the signs and symptoms of oxygen toxicity, particularly in the context of diving with enriched air nitrox. Each letter in the acronym represents different symptoms that divers need to be aware of, such as visual changes, convulsions, and other neurological effects that can occur due to elevated partial pressures of oxygen.

Understanding and recognizing these symptoms is crucial for diver safety; it enables divers to act appropriately if they begin to experience oxygen toxicity. The use of a memorable acronym aids in retention and recall during stressful or high-stakes situations underwater, where immediate recognition of symptoms can be life-saving.

The other options, while they might evoke different associations, do not specifically correspond to the recognized symptoms of oxygen toxicity in divers. The focus provided by "ConVENTID" assists divers in maintaining their safety through awareness and preparedness.
