Sudden drop in oxygen and blood in the brain causes a syncopal episode

2006-07-23 04:27:31 · answer #1 · answered by Anonymous · 0 0

You faint when a drop in blood pressure prevents the brain getting enough oxygen. By falling to the floor, the head is at the same level as the heart, which enables more blood to get to the brain.

The symptoms of a faint are caused by a temporary shortage of blood supply to the brain. The blood carries oxygen, which the brain needs to function. A fall in blood pressure can be caused by a number of different things, including:

* low blood pressure, particularly if you faint after a few days in bed, or as you stand up from a sitting or lying position;
* over-stimulation of an important nerve called the vagus nerve. This causes the heart rate to slow down and lowers the blood pressure. It is called a vaso-vagal attack and is triggered by intense stress, fear or pain;
* anaemia;
* a fall in blood sugar levels, which may happen if you are diabetic, or if you have not eaten anything for a long time;
* fast, shallow breathing (hyperventilation);
* heat exhaustion and dehydration;
* unusually strenuous exercise;
* constipation (straining can cause a reduction in blood supply to the brain);
* menstruation; and
* pregnancy.

its a lack of oxygen to your brain, caused by trumor, its like sleeping.

Of or in a state of unconsciousness; not conscious.
Occurring in the absence of conscious awareness or thought, as an emotion or motive.
Without conscious control; involuntary or unintended.

In psychoanalytic theory, the division of the mind containing elements of psychic makeup, such as memories or repressed desires, that are not subject to conscious perception or control but that often affect conscious thoughts and behavior.

hope you understand.
take care

another good question lol probably more to the point what happens to your brain as it's your brain that tells your body what to do.So if you're unconscious your brain can't tell your body to do anything.(clever eh lol)...so your body waits for your brain to wake up....my brain is still on holiday by the way in the Canary Islands,as you can tell by this answer.lol

depends what knocked you unconcious and what your injuries are. Generally it is similar to sleep. poss more like coma depending on your physical state. It is poss a good design feature as our bodies can begin the repair process much better when our brains are not sending us into panic etc.
