Patent number: 11247009Abstract: A mechanical ventilation device (10) includes a mechanical ventilator. At least one airway sensor (24, 26) is configured to measure at least one of airway pressure and airway air flow as a function of time for a patient on the mechanical ventilator. At least one microprocessor (28, 30) is programmed to analyze at least one of airway pressure and airway air flow measured by the airway sensor to detect a spontaneous respiration anomaly in respiratory muscle pressure as a function of time generated by a patient on the mechanical ventilator. A display component (22) is configured to display an indication of a spontaneous respiration anomaly detected by the anomaly detection component.Type: GrantFiled: October 13, 2016Date of Patent: February 15, 2022Assignee: Koninklijke Philips N.V.Inventors: Francesco Vicario, Antonio Albanese, Dong Wang, Nicolas Wadih Chbat

Patent number: 11179105Abstract: The invention provides a physiological probe that comfortably attaches to the base of the patient's thumb, thereby freeing up their fingers for conventional activities in a hospital, such as reading and eating. The probe, which comprises a separate cradle module and sensor module, secures to the thumb and measures time-dependent signals corresponding to LEDs operating near 660 and 905 nm. The cradle module, which contains elements subject to wear, is preferably provided as a disposable unit.Type: GrantFiled: March 25, 2019Date of Patent: November 23, 2021Assignee: SOTERA WIRELESS, INC.Inventors: Devin McCombie, Gunnar Trommer, Jim Moon, Marshal Dhillon, Scott Clear, Julian Groeli

Patent number: 11141553Abstract: A patient ventilation system includes a ventilator configured to deliver ventilation gas to patient, a CO2 concentration sensor configured to provide EtCO2 measurements for the patient, and an SpO2 monitor configured to determine an SpO2 value for the patient. A ventilation control module is executable on a processor and configured to compare the SpO2 value to a threshold SpO2 and determine from this comparison that the SpO2 value indicates inadequate oxygenation. A minimum ventilation amount is then set, and the ventilator is then controlled based on the EtCO2 measurements and the minimum ventilation amount so as to deliver at the least the minimum ventilation amount to the patient while the SpO2 value indicates inadequate oxygenation.Type: GrantFiled: July 11, 2018Date of Patent: October 12, 2021Assignee: General Electric CompanyInventor: Erkki Paavo Olavi Heinonen
