A vegetative person is generally unconscious and cannot hear others, except when he or she is in the waking stage. A vegetative person has no conscious activity and cannot carry out commands; he or she has voluntary respiration and blood pressure, may open his or her eyes automatically or in response to stimulation, has purposeless eye movements, and may be incontinent. Most of the vegetative patients have no possibility of awakening. For the family conditions allow, even if their family members are diagnosed as vegetative, but still do not give up the treatment, and actively give brain resuscitation treatment (such as hypothermia, head selective cooling treatment, etc.), some people can recover, in the process of recovery will appear conscious and hear people around them. Whether the vegetative person has consciousness or not, we need to find a professional doctor to evaluate, do not be disturbed by some of his instinctive reaction.
