Abstract: Methods and apparatus for accessing and monitoring the gastrointestinal tract are described herein. One variation of a feeding tube system may generally comprise a gastric access device having a length, a controller in communication with the gastric access device, and one or more impedance or conductivity sensors positioned along the length and one or more temperature sensors positioned along the length. The controller may be configured to receive a first signal associated with the impedance or conductivity sensors and a second signal associated with respiration and determine whether a placement of the gastric access device is within a stomach of the subject.

Abstract: Methods and apparatus for guiding medical care based on sensor data from the gastrointestinal tract are described utilizing an apparatus which can be used with enteral feeding. Generally, the apparatus includes an elongated body having a length configured for insertion into a stomach and at least one pair of electrodes located along the length of the elongated body and positionable for placement within the stomach. A controller in electrical communication with the at least one pair of electrodes is included and the control may also be configured to measure a conductivity or impedance between the pair of electrodes and to determine a gastric residual volume of the stomach based on the measured conductivity or impedance.
