EGG Setup. (a) This cartoon shows a standard enteral feeding tube setup utilized in neonatal intensive care units. (b) Setup of three EGG electrodes. The negative electrode (marked by ‘1 (−)’) is placed on the left upper quadrant, near the mid-clavicular line. The positive electrode (marked by ‘2 (+)’) is placed midway between the bottom of breastbone and the belly button, slightly below the level of the negative electrode. The ground electrode (marked by ‘3(g)’) is placed at the mid-axillary line, below the left costal margin.
