摘要： A monitoring catheter that inserts into the patient's esophagus alone or in combination with an existing catheter, such as a feeding or aspiration tube. The monitoring catheter includes a pair of EMG electrodes on an exposed surface that contact the patient's esophageal wall to measure the activity of the diaphragm and/or a pair of pressure detecting mechanisms that measure the pressures within the patient at separate locations. The electrodes are sized and spaced from one another so as to maximize detection of diaphragm muscle activity while minimizing detection of noise. The pressure detecting mechanisms are sized and spaced apart to measure the patient's esophageal and gastric pressures, for example. If necessary, an attaching mechanism secures at least a portion of the monitoring catheter to the existing catheter so that the monitoring catheter uses the existing catheter as a tracking guide.
