N2 - To the Editor: Our blood volume always equals our vascular volume. If water is withheld, the balance may be maintained either by vasoconstriction, which is rapid, or by movement of water, which is slow. Both mechanisms are used together, but since the elderly are less able to vary vascular volume than the young, it is likely that they rely more on the withdrawal of water from cells. This can be done only by raising the plasma osmotic pressure above that of its surroundings, and the old would be expected to have a greater rise in sodium concentration and osmolality, as.
