A system for positioning of a naso/orogastric feeding tube. The system comprises an interface adapted to receive a combined impedance measure comprising a plurality of impedance readings from a plurality of impedance sensors disposed in a plurality of segments along a lateral surface of a naso/orogastric feeding tube； wherein one of the plurality of segments is located to be at least 1 centimeters above another of the plurality of segments when the naso/orogastric feeding tube is in a feeding position, a code store for storing a code, a processor coupled to the interface and the program store for implementing the stored code, the code comprising code to calculate an estimation of a position of the naso/orogastric feeding tube according to the combined impedance measure, and code to generate instructions for a caregiver to relocate the naso/orogastric feeding tube according to the estimation.
