What does the "C" in the acronym CONVENTID stand for?

The "C" in the acronym CONVENTID stands for Convulsions. This term refers to a sudden, uncontrolled electrical disturbance in the brain that can cause changes in behavior, movements, feelings, and consciousness. In the context of diving and decompression illness, convulsions can potentially indicate a serious condition related to nitrogen narcosis or oxygen toxicity, which can occur when divers are exposed to altered environmental pressures or gas mixtures. Recognizing convulsions and understanding their implications is crucial in emergency scenarios, as they require immediate medical attention and intervention. Understanding the signs related to diving-related conditions helps divers make informed decisions when they encounter symptoms during or after a dive.
