Patent number: 8801625Abstract: Methods for noninvasively determining a pulmonary capillary blood flow or a cardiac output of a subject include determining data of the amount of gas exchanged between blood and gas in lungs of the subject, as well as data of an indicator of the content of the gas in blood of the subject. Such a determination may be made during two or more different states of ventilation. A geometric relationship is identified between data points, with any data points outlying the geometric relationship being disregarded. The remaining data points may be used to estimate or calculate a measure of pulmonary capillary blood flow or cardiac output. Systems that include elements that are configured to effect such methods are also disclosed.Type: GrantFiled: February 3, 2006Date of Patent: August 12, 2014Assignee: RIC Investments, LLCInventors: Joseph A.

Patent number: 8398559Abstract: Methods for estimating the volume of the carbon dioxide stores of an individual's respiratory tract include determining a carbon dioxide store volume at which a correlation between corresponding signals of carbon dioxide elimination and an indicator of the content of carbon dioxide in blood of the individual is optimized. The estimate of the volume of carbon dioxide stores, which comprises a model of the respiratory tract, or lungs, of the individual, may be used as a transformation to improve the accuracy of one or both of the carbon dioxide elimination and carbon dioxide content signals. Transformation, or filtering, algorithms are also disclosed, as are systems in which the methods and algorithms may be used. The methods, algorithms, and systems may be used to accurately and noninvasively determine one or both of the pulmonary capillary blood flow and cardiac output of the individual.Type: GrantFiled: July 10, 2006Date of Patent: March 19, 2013Assignee: Respironics, Inc.Inventors: Kai Kück, Joseph A.

Patent number: 7025731Abstract: A method for noninvasively determining the pulmonary capillary blood flow or cardiac output of a patient includes measurement of respiratory flow and carbon dioxide pressure of the patient's breathing. These measurements are used to calculate carbon dioxide elimination and an indicator of the carbon dioxide content of the patient's blood. A geometric relationship between the carbon dioxide elimination data and the data of the indicator of carbon dioxide content is determined. At least one set of the data is modified and at least one other determination of a geometric relationship between the data is made to find the most accurate data set. The data may be modified by filtering or clustering. A slope of at least a portion of the geometric relationship is then used to determine the pulmonary capillary blood flow or cardiac output of the patient.Type: GrantFiled: March 27, 2003Date of Patent: April 11, 2006Assignee: Ric Investments, Inc.Inventors: Joseph A.

Patent number: 6540689Abstract: A method of noninvasively determining the pulmonary capillary blood flow or cardiac output of a patient, including the use of rebreathing techniques to measure the respiratory flow and carbon dioxide pressure of the patient's breathing. These measurements are used to calculate carbon dioxide elimination and an indicator of the carbon dioxide content of the patient's blood, such as the end-tidal pressure of carbon dioxide (PetCO2), CaCO2, or pCO2. The location and orientation of a best-fit line through the carbon dioxide elimination data and the data of the indicator of carbon dioxide content is determined by linear regression or by plotting the carbon dioxide elimination data against the data of the indicator of carbon dioxide content. At least one set of the data is modified and at least one other determination of the best-fit line made to find a data set that correlates most closely to the best-fit line. The data may be modified by filtering or clustering.Type: GrantFiled: February 22, 2000Date of Patent: April 1, 2003Assignee: NTC Technology, Inc.Inventors: Joseph A. Orr, Kai Kück

Patent number: 6258038Abstract: A method of non-invasively estimating the intrapulmonary shunt in a patient. The method includes non-invasively measuring respiratory flow, respiratory carbon dioxide content, and arterial blood oxygen content. A re-breathing process is employed to facilitate an estimate of the patient's pulmonary capillary blood flow. Any inaccuracies of the arterial blood oxygen content are corrected to provide a substantially accurate arterial blood oxygen content measurement. The respiratory flow, carbon dioxide content and arterial blood oxygen content measurements, and the pulmonary capillary blood flow estimate are employed to estimate an intrapulmonary shunt of the patient. The invention also includes a method of determining the total cardiac output of the patient which considers the estimated intrapulmonary shunt.Type: GrantFiled: December 16, 1999Date of Patent: July 10, 2001Assignee: NTC Technology, Inc.Inventors: Dinesh G.

Patent number: 6238351Abstract: A method of compensating for non-metabolic changes in respiratory or blood gas parameters including generating a compensatory signal based on the magnitude of the non-metabolic change and the amount of time elapsed since the onset of the non-metabolic change. The method of the present invention is useful for compensating for non-metabolic changes in non-invasive carbon dioxide elimination measurements and, particularly, when carbon dioxide elimination is employed to determine cardiac output on a non-invasive, continuous basis.Type: GrantFiled: September 9, 1998Date of Patent: May 29, 2001Assignee: NTC Technology Inc.Inventors: Joseph A.

Patent number: 6217524Abstract: A method of continuously, non-invasively determining the cardiac output of a patient. The method includes intermittently measuring the cardiac output, the volume of carbon dioxide exhaled by the patient per breath, and determining the arterial-venous gradient of the patient or a similar substantially constant value by dividing the volume of carbon dioxide exhaled by the measured cardiac output. The arterial-venous gradient or similar substantially constant value may then be employed to determine the cardiac output of the patient on a breath-by-breath basis. The carbon dioxide elimination, which is non-invasively measured as the volume of carbon dioxide exhaled by the patient per breath, is divided by the arterial-venous gradient or the substantially constant value to determine the cardiac output.Type: GrantFiled: September 9, 1998Date of Patent: April 17, 2001Assignee: NTC Technology Inc.Inventors: Joseph A. Orr, Michael B. Jaffe, Kai Kück, Dinesh G. Haryadi

Patent number: 6210342Abstract: A re-breathing method for determining pulmonary capillary blood flow that accounts for changes in the cardiac output or in the carbon dioxide content of the venous blood of a patient. The carbon dioxide elimination and partial pressure of end tidal carbon dioxide of the patient are non-invasively measured prior to re-breathing, during re-breathing, and after re-breathing. The carbon dioxide elimination and the carbon dioxide content of the alveolar blood of the patient at each of the before, during, and after re-breathing phases are then used to calculate the pulmonary capillary blood flow of the patient. A rate of change of carbon dioxide content of the venous blood of the patient may also be calculated and employed in calculating the pulmonary capillary blood flow of the patient.Type: GrantFiled: September 8, 1999Date of Patent: April 3, 2001Assignee: NTC Technology, Inc.Inventors: Kai Kück, Joseph A.
