Patent number: 8672858Abstract: A method of creating a noninvasive predictor of both physiologic and imposed patient effort of breathing from airway pressure and flow sensors attached to the patient using an adaptive mathematical model. The patient effort is commonly measured via work of breathing, power of breathing, or pressure-time product of esophageal pressure and is important for properly adjusting ventilatory support for spontaneously breathing patients. The method of calculating this noninvasive predictor is based on linear or non-linear calculations using multiple parameters derived from the above-mentioned sensors.Type: GrantFiled: February 20, 2012Date of Patent: March 18, 2014Assignee: University of Florida Research Foundation, Inc.Inventors: Neil R. Euliano, Victor L. Brennan, Paul B. Blanch, Michael J. Banner

Patent number: 8652058Abstract: A blood vessel pressing cuff includes a strap surrounding a body part, a first actuator disposed on the strap and including a first shape memory alloy which changes to a first shape memorized in advance, at a temperature equal to or higher than a first temperature, and a second actuator disposed on the strap and including a second shape memory alloy which changes to a second shape memorized in advance, at a temperature equal to or higher than a second temperature that is different from the first temperature. If the first shape memory alloy changes to the first shape, pressure applied to the body part surrounded by the strap is increased. Even when the first shape memory alloy changes to the first shape, if the second shape memory alloy changes to the second shape, the pressure applied to the body part surrounded by the strap is reduced.Type: GrantFiled: April 1, 2010Date of Patent: February 18, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Youn-ho Kim, Kun-soo Shin, Hong-sig Kim, Byung-hoon Ko

Patent number: 8641631Abstract: A method and apparatus for estimating a respiratory rate of a patient. The method comprises the steps of recording respiratory sounds of the patient, deriving a plurality of respiratory rates from the recorded sounds using a plurality of respiratory rate estimating methods and applying a heuristic to the plurality of derived respiratory rates, the heuristic selecting one of the derived respiratory rates. The selected respiratory rate is the estimated respiratory rate. The apparatus comprises at least one sensor recording respiratory sounds of the patient, a plurality of respiratory rate processors, each of the processors comprising a respiratory rate calculating method, a heuristic means for selecting one of the calculated respiratory rates and a display means for displaying the selected respiratory as the estimated respiratory rate.Type: GrantFiled: April 8, 2005Date of Patent: February 4, 2014Assignee: Masimo CorporationInventors: Gilberto Sierra, Victor F. Lanzo, Valery Telfort

Patent number: 8613705Abstract: An implantable system for monitoring a hydration state of a patient and adjusting fluid removal from the patient includes a pressure sensor implantable within an inferior vena cava of the patient and a processor. The pressure sensor senses and generates an output representative of a baseline inferior vena caval pressure value of the patient and chronically senses and generates outputs representative of an inferior vena caval pressure value of the patient. The processor compares differences between the baseline inferior vena caval pressure value and subsequent inferior vena caval pressure values. The processor can reside in another implantable device or in an external device/system.Type: GrantFiled: August 4, 2009Date of Patent: December 24, 2013Assignee: Cardiac Pacemakers, Inc.Inventors: Elizabeth S. Scheurer, Ramesh Wariar

Patent number: 8517941Abstract: An implantable medical device, implantable cardiac stimulation device, implantable defibrillator or pacemaker provides continuous monitoring of blood-glucose concentration in the blood of a patient. Blood-glucose concentration and blood-glucose concentration trends are calculated by measuring changes in the hematocrit of the patient. An external blood-glucose monitor may be used to provide blood-glucose calibration values to the implantable device to enhance accuracy of blood-glucose concentration values. The implantable device compares the blood-glucose concentration and/or concentration trends with acceptable limits and generates appropriate warning signals. The implantable device may optionally control one or more therapeutic devices to maintain blood-glucose concentration within an acceptable range. The enhanced control of blood-glucose concentration reduces the risk of arrhythmia and enhances the effectiveness of cardiac pacing and/or defibrillation.Type: GrantFiled: October 23, 2007Date of Patent: August 27, 2013Assignee: Pacesetter, Inc.Inventor: Brian Jeffrey Wenzel

Patent number: 8469895Abstract: A method of deriving central aortic systolic pressure comprises (a) creating a set having a predetermined number of blood pressure measurements, the set representative of an arterial waveform; (b) determining an integer interval value; (c) averaging a series of consecutive blood pressure measurement readings in the set equal to the integer interval value commencing from the fth blood pressure measurement in the set; (d) storing the averaged value in a central aortic systolic pressure set; and (e) setting the central aortic systolic pressure as the highest value in the central aortic pressure set. Steps (c) and (d) are repeated with the value of f being incremented by 1 each time until the value of f plus the integer interval value equals the predetermined number of blood pressure measurements in the set.Type: GrantFiled: September 24, 2007Date of Patent: June 25, 2013Assignee: Healthstats International Pte LtdInventors: Choon Meng Ting, Ngak Hwee Chua
