Dr. Youngquist: There is a calculation you could do, and you could look this up online, but there are various numbers given for the amount of appropriate fluids. We tend to calculate people's fluids on a maintenance basis when they come into the hospital and have to go without food or water because they're preparing for surgery or something like that. And for an adult we tend to go around 125 to 200 milliliters per hour as a maintenance fluid.
