Abstract: A method for controlling fluid delivery to a medical instrument comprises releasing, from a reservoir of a known size and having fluid at a volume and a first fluid pressure, a released fluid volume of the fluid to the medical instrument. The method also comprises measuring a vented fluid volume and determining a discharged fluid volume through the medical instrument based on the released fluid volume and the vented fluid volume.
