it should increase
because osmotic forces across the alveolar capillary membrane will pull the water into the intravascular space.
remember water across a semi-permeable membrane always moves in such a manner as to normalize the concentration on both sides. so it will move from a region of lower concetration (hypotonicity) to the plasma (hypertonic).
elementary my dear Watson!
