Question

Quizplus · Accepted Answer

Coma is defined as a state of prolonged unconsciousness in which a person does not respond to stimuli. It can be caused by a variety of factors such as traumatic brain injury, stroke, and drug overdose. It is not synonymous with syncope, which is a brief loss of consciousness due to a drop in blood pressure. During coma, brain oxygen consumption is decreased compared to a waking state.
