|---|---|
| Somnolent | Sleepy |
| Obtunded | Decreased alertness; slowed psychomotor responses |
| Stuporous | Sleep-like state (not unconscious); little/no spontaneous activity |
| Comatose | Cannot be aroused; no response to stimuli |
How long can you be unconscious before brain damage occurs?
Time is very important when an unconscious person is not breathing. Permanent brain damage begins after only 4 minutes without oxygen, and death can occur as soon as 4 to 6 minutes later.What are the complications of unconsciousness?
Complications of prolonged unconsciousness can be severe. Lack of oxygen to the brain may result in brain damage, and choking can lead to death if left untreated.

The state of complete unconsciousness with some eye opening and periods of wakefulness and sleep is called the vegetative state. As people recover from severe brain injury, they usually pass through various phases of recovery.How long does someone stay unconscious after being choked out?
After 4 to 6 minutes of sustained cerebral anoxia, permanent brain damage will begin to occur, but the long-term effects of a controlled choke-out for less than 4 minutes (as most are applied for mere seconds and released when unconsciousness is achieved) are disputed.How many stages of coma are there?
Three stages of coma Often lumped under the label of “Coma” are three stages of disordered consciousness. Disorders of Consciousness (DOC) are a set of disorders that effect a person's ability to be awake.
