How long can someone be in a coma and still wake up
A few people never wake up from their coma states.A man who has spent the last 15 years in a coma is now showing signs of consciousness, thanks to a vagus nerve stimulation (vns) device implanted in his chest.In the hospital in staffordshire, england, carter had been in a coma for three days, and he was given a 30 percent chance of recovering.Likewise, even two days before the severe brain injury survivor wakes up, the answer is still unknown.As we would expect, the longer a person is in a coma, the.
Again, coming out of the induced coma and off the ventilator/ respirator after more than 72 hours of ventilation and an induced coma might be a little bit more difficult, because as a rule of thumb, the longer ventilation and the induced coma is required, the higher the risk that complications and/or delays occur of course.A coma is a deep state of unconsciousness that can result from an injury or illness.They found that those who showed less than 42 percent of normal brain activity didn't regain consciousness after a year, while those who had activity above that woke up within a year.The person is still alive, but the brain is functioning at its lowest stage of alertness.Actually, some people will wake up after a few weeks, while others may go into a vegetative or minimally conscious state.
Nqinana's story is proof that sometimes hope and patience prevail, as miraculous awakenings have been reported for patients in comas as long as 19 years.Some people may never wake up from a coma.Some never regain more than basic responses.A person may wake from a coma with physical, intellectual, or emotional problems.And if enough nerve cells die in a region of the brain that's essential for maintaining wakefulness, the person will probably never regain normal consciousness.
The person may gradually regain consciousness over time as he or she becomes more aware and aware of the situation.In some cases, it lasts for just a few days, but in others, the person does not wake up.
