Low blood volume means that you do not have the amount of blood that you should have in your body. This could mean that you only have half, or maybe even more. Low blood volume could mean you are losing blood somewhere.
It doesn't. The opposite is true. Blood pressure is proportional to blood volume. The greater the blood volume is, the higher the blood pressure will be. This is because there will be a greater volume of blood flowing through the blood vessels which means that a greater pressure will be exerted on the walls of the blood vessels, which means increased blood pressure.
