NG:Safe is a Cambridge based medtech startup developing a connected health solution for real-time monitoring of nasogastric feeding tube (NGT) position. Incorrect NGT misplacement is a life-threatening complication and NHS never event, yet still occurs in critical care units across the developed world. NG:Safe’s breakthrough technology exploits fundamental differences between the microenvironments of the lung and stomach to provide a cost effective solution to a growing yet tractable problem in critical care. Together with our clinical collaborators, NG:Safe will eliminate uncertainty in nasogastric feeding tube placement.
