The volume of hemolymph needed for such a system is kept to a minimum by a reduction in the size of the body cavity. The hemocoel is divided into chambers called sinuses. Coordinated movements of the body muscles gradually bring the hemolymph back to the dorsal sinus surrounding the hearts.
Hemolymph fills all of the interior hemocoel of the body and surrounds all cells. Hemolymph is composed of water , inorganic salts (mostly sodium , chloride , potassium , magnesium , and calcium ), and organic compounds (mostly carbohydrates, proteins , and lipids ).
Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), [2] and contains proteins, glucose, ... Hemolymph may function to carry oxygen ...
where EBV is the estimated blood volume; 70 mL/kg was used in this model and H i (initial hematocrit) is the patient's initial hematocrit. From the equation above it is clear that the volume of blood removed during the ANH to the H m is the same as the BL s. How much blood is to be removed is usually based on the weight, not the volume.
It is able to report with 98% accuracy within 60 minutes the Total Blood Volume (TBV), Plasma Volume (PV) and Red Cell Volume (RCV) using the indicator dilution principle, microhematocrit centrifugation and the Ideal Height and Weight Method. [4] The indicator, or tracer, is an I-131 albumin injection. An equal amount of the tracer is injected ...
Red blood cells are the most abundant cell in the blood, accounting for about 40-45% of its volume. Red blood cells are circular, biconcave, disk-shaped and deformable to allow them to squeeze through narrow capillaries. They do not have a nucleus. Red blood cells are much smaller than most other human cells.

The intravascular volume is low because the water will move through a process called osmosis out of the vasculature into the cells (intracellularly). The danger is tissue swelling (edema) the most important being brain edema which in turn will cause more vomiting.
