What are the Stages of coma?

Coma has two principle stages and many intermediary stages. During the first stage of coma patients are incapable of voluntary activities such as eye opening, and speech. In some cases primitive avoidance responses, such as gag reflex, response to noxious stimuli, and responce to pain might be absent. In the second stage of coma, they open their eyes, but they don't do anything. They don't follow commands. They don't speak. They don't interact with their loved ones, this is called a vegitative state.
