Actually, it was NIOSH and NOT WHO.
Here's what will happen if SleepyGal's blood volume gets too low (medicine.net):
For example, low blood volume due to bleeding (such as a bleeding ulcer in your stomach or from a bad laceration from an injury) can cause low blood pressure. The body quickly responds to the low blood volume and pressure by the following adjustments which all increase blood pressure:
- The heart rate increases and the forcefulness of the heart's contractions increase, thus more blood is pumped through the heart.
- Veins narrow to return more blood to the heart for pumping.
- Blood flow to the kidneys decreases to reduce the formation of urine and thereby increases the volume of blood in the arteries and veins.
- Arterioles narrow to increase resistance to blood flow
These adaptive responses will keep the blood pressure in the normal range unless blood loss becomes so severe that the responses are overwhelmed.
So maybe she IS out cold on the floor somewhere.
