Hello, I'm an expert in medical science with a focus on neurology and patient care. I can provide you with an accurate and detailed explanation regarding the ability to breathe during a coma. When a person is in a coma, their brain is not functioning normally, but they are still able to breathe. A coma is a state of unconsciousness where a person cannot be awakened, and they show no responses to external stimuli. However, the basic life functions such as breathing and heartbeat continue because these are controlled by the brainstem, which is the lower part of the brain responsible for these vital functions. In some cases, if the brainstem function is severely impaired, a person may require ventilator assistance to breathe. But as long as the brainstem is functioning, the person can breathe on their own, even if they are in a deep state of unconsciousness. read more >>

Usually, a coma does not last more than a few weeks. Sometimes, however, a person stays in a coma for a long time �� even years �� and will be able to do very little except breathe on his or her own. Most people do come out of comas. Some of them are able to return to the normal lives they had before they got sick.read more >>
