Diuresis used to increase urine output and decrease extracellular fluid volume. Substances in the circulation can also increase the amount of circulating fluid by increasing the osmolarity of the blood. This has the effect of pulling water from the interstitial space, making more water available in the blood and causing the kidney to compensate by removing it as urine. In hypotension, often colloids are used intravenously to increase circulating volume in themselves, but as they exert a certain amount of osmotic pressure, water is therefore also moved, further increasing circulating volume. As blood pressure increases, the kidney removes the excess fluid
Water hog Water hog A water hog is a machine that removes water from sports grounds. The water hog was invented by Hugh McLaughlin. Driven by a rider, it has a wide, front roller that absorbs the water, transfers it to a storage tank, and allows it to be discharged in a safe location. Some water hogs can suck off excess water at a rate of 200 gallons per minute and throw it as far as 100 feet away from the machine. It is designed so that it will not damage the turf. Originally devised for use on cricket pitches, it is
