Abstract An unique disposable pH sensor molded into the end of a nasogastric tube was tested in twelve healthy human volunteers. A Spearman's rank corelation coefficient (r s) of 0.90 was observed for the sensor and an indwelling miniature glass membrane electrode. The sensor did not correlate as well with aspirated stomach fluid (r s=0.68). No sensor calibration was necessary and the sensors measured ±0.1 pH in laboratory pH buffers before and after the clinical study. Both bare and shielded disposable sensors closely agreed with a shielded miniature glass electrode.
