Why would a burette be incorporated into an infusion system?
A burrette is incorporated in an infusion system in situations where fluid volume is to be strictly limited, the burrette is filled with the desired volume and fluid is infused. It is not possible to infuse more than is in the burrette. That way the anesthestist in the case of the operating room is closely monitoring the volume infused. Once infused it is either refilled or not.
