20090076347 | Pattern Recognition System for Classifying the Functional Status of Patients with Chronic Disease - A method employing pattern recognition techniques for identifying the functional status of patients with chronic disease is described. This method describes a process by which sets of cardiopulmonary exercise gas exchange variables are measured during rest, exercise and recovery and stored as unique data sets. The data sets are then analyzed by a series of feature extraction steps, yielding a multi-parametric index (MPI) which reflects the current functional status of a patient. The method also employs a description scheme that provides a graphical image that juxtaposes the measured value of MPI to a reference classification system. An additional description scheme provides a trend plot of MPI values measured on a patient over time to provide feedback to the physician on the efficacy of therapy provided to the patient. The method will enable physicians to gather, view, and track complicated data using well-understood visualization techniques to better understand the consequences of their therapeutic actions. | 03-19-2009 |
20100016750 | Pattern Recognition System for Classifying the Functional Status of Patients with Pulmonary Hypertension, Including Pulmonary Arterial and Pulmonary Vascular Hypertension - A method employing pattern recognition techniques for identifying the functional status of patients with Pulmonary Hypertension is described. This method describes a process by which sets of cardiopulmonary exercise gas exchange variables are measured during rest, exercise and recovery and stored as unique data sets. The data sets are then analyzed by a series of feature extraction steps, yielding a multi-parametric index (MPI | 01-21-2010 |
20100099630 | Method for improving ventilatory efficiency - This invention is a method of improving the function of the pulmonary arm of the cardiac-pulmonary axis by the administration of a pharmaceutical or nutritional supplement to a patient in which the function of the pulmonary arm is suboptimal, but not as a sequella of dysfunction of the cardiac arm. The exemplar patient is one suffering from chronic obstructive pulmonary disease. The preferred pentose is D-ribose, to be administered chronically. | 04-22-2010 |
20100189785 | Use of D-ribose for fatigued subjects - Low doses of D-ribose raise the level of fitness and lower the perception of fatigue in baby boomers aged 45-65 who perceive themselves as fatigued. The doses range from 0.100 grams to 3.0 grams, bid, for a total of 0.200 to 6.0 grams daily. Objective measures of cardiopulmonary parameters confirm the improvement of fitness and questionnaires confirm that quality of life and mental states are improved with D-ribose administration. | 07-29-2010 |
20120045426 | COMPOSITIONS FOR REDUCING THE DELETERIOUS EFFECTS OF STRESS AND AGING - The invention provides a formulation for treating stress and lessening fatigue. The formulation can be combined with water or another suitable liquid to provide a beverage for ease of administration. The formulation can include one or more of an energy compound, a vasodilator, a vasodilator adjuvant, and an antioxidant enhancer. In a typical formulation the energy compound is D-ribose or guanosine. The formulation can improve energy and alertness, and reduce the effects of stress and fatigue. | 02-23-2012 |
20120123493 | Method of Defining Continuous Heart Rate vs AV Delay Values and Sensed to Paced AV Delay Offset in Patients Undergoing Cardiac Resynchronization Therapy - A method of data management for optimizing the patient outcome from the provision of cardiac resynchronization therapy (CRT) is described. A regression equation is constructed using 3 data points on a plot of AV delay vs. HR. The x-axis consist of the three points consist of resting HR, HR at the optimal AV delay value during light exercise, and the upper tracking or paced HR. The y-values associated with the three points consist of the AV delay values computed using an equation for ventricular filling time and the optimally determined AV delay value. Also described is a process for determining the sensed to paced AV delay offset. The combined processes yield 4 (the three constant values in the polynomial regression equation Y=b | 05-17-2012 |
20120264701 | USE OF D-RIBOSE FOR FATIGUED SUBJECTS - Low doses of D-ribose raise the level of fitness and lower the perception of fatigue in baby boomers aged 45-65 who perceive themselves as fatigued. The doses range from 0.100 grams to 3.0 grams, bid, for a total of 0.200 to 6.0 grams daily. Objective measures of cardiopulmonary parameters confirm the improvement of fitness and questionnaires confirm that quality of life and mental states are improved with D-ribose administration. | 10-18-2012 |
20120265447 | METHOD FOR COMBINING INDIVIDUAL RISK VARIABLES DERIVED FROM CARDIOPULMONARY EXERCISE TESTING INTO A SINGLE VARIABLE - A method of pattern recognition for classifying the functional status of patients with chronic disease comprising characterizing the functional status based on a multivariable index (MVI) scoring system wherein the MVI is computed by summing a plurality of individual variable values as individual variable indexes (IVI) and dividing the sum by the number of variables and wherein the plurality of IVI includes rest PetCO | 10-18-2012 |
20140163397 | Gas Exchange Testing and Auxiliary Gas Delivery Apparatus - A gas exchange testing system has an apparatus for delivery of an auxiliary gas during a gas exchange test. Measurements representing physiological parameters of a patient are made during the gas exchange test. The auxiliary gas is delivered so that a gas exchange test can be performed on a patient who requires auxiliary gas. Additionally, the auxiliary gas is delivered so that gas exchange testing can determine if the auxiliary gas is beneficial and which concentration of the auxiliary gas is most beneficial. A testing process compares measurements under a condition where the auxiliary gas is delivered and under a condition where it is not delivered. Another testing process compares measurements under a condition where one auxiliary gas is delivered and under a condition where a different auxiliary gas is delivered. | 06-12-2014 |
20150032018 | PATTERN RECOGNITION SYSTEM FOR QUANTIFYING THE LIKELIHOOD OF THE CONTRIBUTION OF MULTIPLE POSSIBLE FORMS OF CHRONIC DISEASE TO PATIENT REPORTED DYSPNEA - Systems and methods for quantifying the likelihood of the contribution of multiple possible forms of chronic disease to patient reported dyspnea can include the testing protocol having a flow/volume loop, performed at rest, flowed by the measurement of cardiopulmonary exercise gas exchange variables during rest, exercise and recovery as unique data sets. The data sets are analyzed using feature extraction steps to produce a pictorial image consisting of disease silos displaying the likelihood of the contribution of various chronic diseases to patient reported dyspnea. In some embodiments, the silos are split into subclass silos. In some embodiments, multiple chronic disease indexes are used to differentiate between sub-types of a particular chronic disease (e.g., differentiating WHO 1 PH from WHO 2 or WHO 3 PH). Test results are plotted serially to asses to provide feedback to the physician on the efficacy of therapy provided to the patient. | 01-29-2015 |
