11. Dehydration is distinct from hypovolemia ( loss of blood volume , particularly plasma ). 12. Reduced blood volume , hypovolemia, is the most common cause of hypotension. 13. Thus, cuff pressure is increased until the excess blood volume is squeezed out. 14. The use of relative blood volume changes during dialysis is of questionable utility. 15. Heat causes vaso-dilation and worsens the effect of the relatively insufficient blood volume . 16. This in turn results in an increase of blood pressure and blood volume . 17. The low-pressure baroreceptors are involved with the regulation of blood volume . 18. Though, blood volume is expected to be reduced in liver cirrhosis. 19. The blood volume in one human is approximately 4.7 liters or 4700 milliliters. 20. A third heart sound, S3 usually indicates an increase in ventricular blood volume .
