摘要：
A tubing assembly for use in conjunction with electronic catheter guidance systems is provided and includes a catheter and a sensor. The catheter extends in a longitudinal direction and has a proximal end and a distal end that define a lumen therebetween. Further, the catheter is configured for placement within a digestive tract of a patient. The sensor includes a temperature sensor, relative humidity sensor, or both, and can be located within the lumen of the catheter or in an air sampling chamber connected to the catheter. The sensor can communicate with a processor to deliver temperature and/or relative humidity readings to a display device. A constant temperature or relative humidity profile, or both after a pre-determined amount of time can indicate placement of the catheter in the digestive tract. A catheter guidance system and a method for accurately placing a catheter in the digestive tract are also provided.
