An apparatus, system and method for detecting the distance between a plurality of position detectors using ultrasound is provided. The position detection system includes a processor and a memory device. The position detection system further includes a first position detector device configured to detect the position of a medical device within a patient, the first position detector device comprising a first transceiver, further wherein the first position detector device is operatively coupled to the processor; and a second position detector device configured to detect the position of a medical device within a patient, the second position detector device comprising a second transceiver, further wherein the second position detector device is operatively coupled to the processor. The memory device stores instructions which when executed by the processor, cause the processor to: instruct the first position detector device to transmit a signal through the first transceiver; receive a signal from the second position detector device relating to the distance between the first position detector device and the second position detector device; and calculate the distance between the first position detector device and the second position detector device. Each transceiver is configured to transmit and receive one or more sound signals in the audio or ultrasonic range.

A tubing assembly for use with electronic catheter guidance systems is provided and includes a catheter and an acoustic 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 patient's digestive tract. The acoustic sensor can be located within the lumen of the catheter or in a sampling chamber connected to the catheter. The acoustic sensor can communicate with a processor to deliver sound data to a display device. The appearance of random spikes on a frequency versus time spectrogram can indicate placement of the catheter in the digestive tract, while a rhythmic/repetitive pattern on a frequency versus time spectrogram can indicate placement of the catheter in the respiratory tract. A catheter guidance system and method for accurately placing a catheter in the digestive tract are also provided.
