syncope-Syncope ( /ˈsɪŋkəpi/ sing-kə-pee) is the medical term for fainting, a sudden, usually temporary, loss of consciousness generally caused by insufficient oxygen in the brain either through cerebral hypoxia or through hypotension, but possibly for other reasons. A pre- or near-syncope is diagnosed if the individual can remember events during the loss of consciousness (i.e., reports remembering dizziness, blurred vision, and muscle weakness, and the fall previous to hitting his or her head and losing consciousness). As loss of consciousness is a symptom for a variety of conditions and syncope is difficult to rule out outside of a hospital, a thorough examination is required in order to determine the cause, including interviews with witnesses as well as evaluation with an electrocardiogram. If the individual remembers feeling dizzy and loss of vision, but not the fall, then it is considered a syncoptic episode. Typical symptoms progress through dizziness, clamminess of the skin, a dimming of vision or greyout, possibly tinnitus, complete loss of vision, weakness of limbs to physical collapse. These symptoms falling short of complete collapse, or a fall down, may be referred to as a syncoptic episode. A breathing gas containing less than 16% oxygen can still contain enough to prevent hypoxia. On the other hand, mountaineers, pilots, and astronauts breathe oxygen-enriched gas because the partial pressure of oxygen in normal air mixture is not enough to prevent hypoxia, since the total pressure is reduced at high altitude. Syncope due to hypoxia can also occur because the lungs are not working properly, because a person is not breathing, because the blood is not circulating, or because the blood's ability to transport oxygen is destroyed or blocked, e.g., by carbon monoxide, which, if present, binds itself to the blood's hemoglobin.

if he is fainting for such a silly reason, then there is probably an underlying medical condition. thats all i am saying. not arguing that he isnt fainting just that there is probably some reason medically.
threads are for discussion purposes. everybody has and opinion and will state it, doesnt mean that it is necessarily against you! could be for information purposes or just because one wants to give their opinion. no need to take everything so personal
i learn tons from these threads like this. they make me think and try and reason out things, that is a good thing!
(and i deal with this stuff, ie blood flow to the brain, every day. it is pretty important in animals as well you know
)
