Publication number: 20140276120Abstract: A method and apparatus for monitoring changes in the intra-thoracic pressure of a patient due to the patient's respiratory activity or volumetric changes in the extra-thoracic arterial circulatory system due to cardiac function based on the changes in pressure in the patient's extra-thoracic arterial circulatory system as measured by a plethysmography sensor, such as an photoplethysmograph. A frequency spectrum is generated for the plethysmograph signal and the frequencies of interest is isolated from the frequency spectrum by setting appropriate cutoff frequencies for the frequency spectrum. This isolated frequency is used to filter the plethysmograph signal to provide a signal indicative of the patient's respiratory activity or cardiac function.Type: ApplicationFiled: December 18, 2012Publication date: September 18, 2014Inventors: Eric W. STARR, James A. SCULL, Eric AYERS, Bernie F. HETE, Donald S. WILCZEK, Mark H. SANDERS

Patent number: 6259938Abstract: 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.Type: GrantFiled: May 13, 1999Date of Patent: July 10, 2001Assignee: Respironics, Inc.Inventors: Jaroslaw Zarychta, Eugene N. Scarberry, Mark H. Sanders, Gregory L. Walker, Mark F. Sauerburger
