Patent number: 10987023Abstract: A system is configured to determine one or more breathing parameters of a subject, such as one or both of end-tidal carbon dioxide concentration and/or breath rate. The system is configured to make a plurality of preliminary determinations of an individual breathing parameter according to a plurality of different algorithms. A final determination of the breathing parameter is obtained by selecting one of the preliminary determinations based on therapy parameters, gas parameters, and/or other parameters that impact the accuracy and/or precision of the different algorithms.Type: GrantFiled: December 9, 2011Date of Patent: April 27, 2021Assignee: Koninklijke Philips N.V.Inventors: Michael Brian Jaffe, Joseph Allen Orr

Patent number: 10094810Abstract: A detector to measure composition of a flow of gas from a respiratory circuit. The detector includes a housing and a removable flow path element. The removable flow path element includes an inlet, a sampling chamber, a pump section including a membrane and an actuator interface, and an outlet. A flow path element dock is formed by the housing with the flow path element dock to removably engage the removable flow path element. A radiation source within the housing emits radiation into a sampling chamber of the removable flow path element while the removable flow path element is docked in the flow path element dock. A sensor is housed within the housing. A pump actuator and controller are within the housing to drive the pump to maintain the flow rate of the flow of breathable gas through an enclosed flow path.Type: GrantFiled: November 2, 2012Date of Patent: October 9, 2018Assignee: Koninklijke Philips N.V.Inventors: Michael Brian Jaffe, David Scampoli

Patent number: 9855395Abstract: Gas-pressure-based testing, in some embodiments, features a self-leak-testing module (120) that includes an internal sensor and is configured for measuring, using the sensor, gas leakage (179, 180) from a set of walls that defines respective gas passageways that both exist within the module and are incident to the gas pressure measured. One or more walls of the set may extend outside the module. The module can be configured for deciding, based on a result of the measuring, whether a magnitude of the leakage exceeds a predetermined threshold. A source for applying the pressure may be internal (138) or external (104, 132, 135). Gas pressure based pattern recognition can be used to identify, optionally during treatment and in real time, one or more leak sites responsible for the leakage. The module is implementable as a ventilation monitoring module that measures differential flow of a breathing circuit, the testing serving to prevent cross-contamination of patients.Type: GrantFiled: September 10, 2012Date of Patent: January 2, 2018Assignee: Koninklijke Philips N.V.Inventors: Michael Brian Jaffe, Joseph Allen Orr

Patent number: 9521963Abstract: A respiratory component measurement system that includes an airway adapter adapted to be placed in fluid communication with an airway of a patient and a sensor element in physical communication with the airway adapter. The sensor element is adapted to detect an orientation related characteristic of the airway adapter, a motion related characteristic of the airway adapter, or both. A respiratory component sensor is also adapted to be disposed on the airway adapter so as to measure a characteristic associated with a flow of gas through the airway adapter. An indicating element coupled to the respiratory component sensor is adapted to output a representation of the orientation related characteristic.Type: GrantFiled: December 29, 2009Date of Patent: December 20, 2016Assignee: RIC Investments, LLCInventors: Anthony James Esposito, Michael Brian Jaffe

Patent number: 9446210Abstract: Sidestream sampling of gas to determine information related to the composition of gas at or near the airway of a subject is implemented. From such information one or more breathing parameters of subject 12 (e.g., respiratory rate, end-tidal CO2, etc.) are determined, respiratory events (e.g., obstructions, apneas, etc.) are identified, equipment malfunction and/or misuse is identified, and/or functions are performed. To improve the accuracy of one or more of these determinations, information related to pressure at or near the airway of subject is implemented. This information may include detection of pressure at or near a sidestream sampling cell.Type: GrantFiled: October 11, 2010Date of Patent: September 20, 2016Assignee: Koninklijke Philips N.V.Inventors: Joseph Allen Orr, Michael Brian Jaffe

Publication number: 20150320949Abstract: An apparatus comprises a flow sensor configured to sense airflow between a respiration machine and a patient, a first connector configured to communicate air between the flow sensor and the patient, a second connector configured to communicate air between the flow sensor and the respiration machine, multiple pressure sensing ports configured for connection to pressure sensing tubes and configured to communicate gas pressure between the flow sensor and a pressure flowmeter, and a filter integrated with the flow sensor between the first connector and the pressure sensing ports and configured to communicate gas pressure therethrough while preventing contaminants from passing from the flow sensor to the pressure sensing tubes.Type: ApplicationFiled: December 21, 2012Publication date: November 12, 2015Inventor: Michael Brian JAFFE

Publication number: 20140326048Abstract: A system and method are configured to monitor composition of a flow of breathable gas being provided to a subject. A measurement flow of breathable gas is diverted in order to monitor composition of the flow of breathable gas, and then the measurement flow of breathable gas is returned to the flow of breathable gas. This will tend to conserve the constituent gases within the flow of breathable gas, which may be significant in instances where the flow of breathable gas is being used to deliver medicaments or drugs (e.g., relatively expensive anesthetic, and/or other medicaments or drugs). Since the measurement flow of breathable gas will tend to have contaminants (e.g., mucus blood, medications, or other materials), routing the measurement flow of breathable gas back into the flow of breathable gas constitutes a placement solution for the contaminants.Type: ApplicationFiled: November 2, 2012Publication date: November 6, 2014Inventors: Michael Brian Jaffe, David Scampoli

Publication number: 20130018288Abstract: Cardiopulmonary resuscitation being provided to a subject is monitored. An enhanced measurement of the effectiveness of the cardiopulmonary resuscitation received by the subject is determined by correlating chest compressions with changes in movement and/or composition of gas at or near the airway of the subject. For example, one or more therapy parameters may be measured with an enhanced accuracy and/or precision, and/or one or more therapy parameters not monitored in conventional cardiopulmonary resuscitation monitoring systems may be measured.Type: ApplicationFiled: March 17, 2011Publication date: January 17, 2013Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventor: Michael Brian Jaffe
