unseen passage related to topic on consciousness unconsciousness and coma

Answer:
What do u exactly want!?
Answer:Consciousness is not a lights-on/lights-off proposition, which the term unconscious implies. It's like being underwater. The deeper you go, the darker the surroundings. As you get closer to the surface you start to see more things and be more cognizant of what's out there, until you break through to total awareness.
Health care workers call this sliding scale of awareness the levels of consciousness. Being fully awake, alert, and oriented to your surroundings is the gold standard. It's the way most of us go through our days (other than Mondays anyway).
Anything other than that gold standard is considered altered, hence the term altered levels of consciousness. The deepest, darkest level is usually described as being unresponsive, meaning nothing you do to the patient—smells, touch, noises, pain—will arouse them to any sort of response.
Coma is a simplistic term for an unconscious patient who is unresponsive to verbal or physical attempts to wake him or her.1 Usually, the term coma is used for patients who exhibit unresponsiveness for long periods of time.
The Role of Brain Function
Consciousness is a function of the brain and altered levels of consciousness are indicators that something is amiss. In that way, an altered level of consciousness is a sign of a medical condition, rather than a medical condition in itself. The more acute or sudden changes in consciousness occur, the more we are usually concerned about what it means.
For example, sudden cardiac arrest leads to a sudden loss of consciousness because blood stops flowing to the brain. In cardiac arrest, the brain isn't the problem—the heart is. However, the sudden loss of consciousness is an obvious indicator of a problem.
