Performance of the NGPOD® Device in Verifying the Correct Position in the Stomach of the Naso- or Oro- Gastric Tube in Intensive Care.

"The NGPOD sensor is inserted into the naso- or oro-gastric tube, then reconnected to the NGPOD handheld device, and the pH measurement is taken within 15 seconds.~When the 15 seconds have elapsed, the pH button is pressed. If the green LED lights up and the pH indicates a value \< 5.5, the sensor tip is in a pH environment associated with the stomach.~If the red LED lights up, the sensor tip is in a pH environment NOT associated with the stomach."
