^{a}Geometric volume of the balloon was calculated by the length and diameter of the balloon, using the capsule body as approximation. Because the feeding tube passed through the inner space of the balloon in SmartCathG catheter, this volume was deducted in the calculation of balloon geometric volume in this type of catheter
