hyperventilating is breathing too fast and/or deeply. It causes overly low blood CO2 levels, which cause high blood alkalinity, which causes constriction of blood vessels supplying the brain, which causes all the other symptoms associated with it.
Hypovolemia is when blood plasma levels fall dangerously low: http://en.wikipedia.org/wiki/Hypovolemic_shock Shelly’s was probably caused by dehydration. The cyanosis in her extremities would have happened because there was not enough plasma to transport oxygenated red blood cells to them.
Hypovolemia can also be caused by long-term bleeding, also known as “bleeding out”. I did that once. While it appears to have cured an incurable condition (Congestive Heart Failure) I can’t recommend it. In the days leading up to my hospitalization, the feeling of not enough oxygen to keep me alive truly sucked.
.. Holy hell. Poor Shelly. o.o She would’ve looked a mess. ;_;
hyperventilating and totally out to lunch…not good.
