Leak-Compensated Flow Triggering And Cycling In Medical Ventilators

View page
US Patent:
8272379, Sep 25, 2012
Filed:
Sep 30, 2008
Appl. No.:
12/242741
Inventors:
Mehdi M. Jafari - Laguna Hills CA, US
Jeffrey K. Aviano - Escondido CA, US
Rhomere S. Jimenez - Winchester CA, US
Gail F. Upham - Fallbrook CA, US
Assignee:
Nellcor Puritan Bennett, LLC - Boulder CO
International Classification:
A61M 11/00
US Classification:
12820421
Abstract:
This disclosure describes systems and methods for compensating for inelastic and elastic leaks in a ventilation system. The disclosure describes a model-based enhancement to conventional flow triggering and cycling methodologies that improves the timing and patient work of flow-based triggering and cycling performance. The methods and systems described herein compensate for the leak condition and minimize additional effort a patient has to exert to generate the same patient synchrony and comfort level compared to no leak condition. One method described includes calculating an elastic leakage and an inelastic leakage based on current measurements of pressure and flow in the ventilation system and then estimating a leak-compensated lung flow using the inelastic and elastic leaks and pneumatic attributes of the patient-ventilator system.

US Patent:
8272380, Sep 25, 2012
Filed:
Sep 30, 2008
Appl. No.:
12/242756
Inventors:
Mehdi M. Jafari - Laguna Hills CA, US
Jeffrey K. Aviano - Escondido CA, US
Rhomere S. Jimenez - Winchester CA, US
Gail F. Upham - Fallbrook CA, US
Assignee:
Nellcor Puritan Bennett, LLC - Boulder CO
International Classification:
A61M 11/00
US Classification:
12820421
Abstract:
This disclosure describes systems and methods for compensating for inelastic and elastic leaks in a ventilation system. The disclosure describes a model-based enhancement to conventional pressure triggering methodology that optimizes the timing and patient work of pressure triggering performance. The methods and systems described herein compensate for the additional effort a patient has to exert to generate the same amount of airway pressure drops compared to no leak condition. One method described includes calculating an elastic leakage and an inelastic leakage based on current measurements of pressure and flow in the ventilation system and then compensating a pressure threshold for the effects of the inelastic and elastic leaks in the system.

Leak-Compensated Proportional Assist Ventilation

Appl. No.:
12/408408
Inventors:
Mehdi M. Jafari - Laguna Hills CA, US
Rhomere S. Jimenez - Winchester CA, US

Nellcor Puritan Bennett LLC - Boulder CO
International Classification:
F16K 31/02
US Classification:
12820421, 12820222, 12820418, 12820422, 12820423
Abstract:
This disclosure describes systems and methods for compensating for leakage when during delivery of gas from a medical ventilator in a proportional assist mode to a patient. The technology described herein includes systems and methods to compensate the delivery of PA ventilation for leakage in the patient circuit by using leak-compensated lung flows as well as leak-compensated respiratory mechanics parameters (lung compliance and lung resistance) estimated in a manner that compensates for elastic and inelastic leaks from the ventilation system.

Leak-Compensated Pressure Regulated Volume Control Ventilation

US Patent:
8418691, Apr 16, 2013
Filed:
Mar 20, 2009
Appl. No.:
12/408414
Inventors:
Mehdi M. Jafari - Laguna Hills CA, US
Rhomere S. Jimenez - Winchester CA, US
Gail F. Upham - Fallbrook CA, US
Jeffrey K. Aviano - Escondido CA, US
Assignee:
Covidien LP - Mansfield MA
International Classification:
F16K 31/02
US Classification:
12820421, 12820024, 12820418, 12820423
Abstract:
This disclosure describes systems and methods for compensating for leakage when during delivery of gas to a patient from a medical ventilator in a pressure regulated volume control (PRVC) ventilation mode. The technology described herein includes systems and methods that compensate the delivery of PRVC ventilation for leakage in the patient circuit by using leak-compensated lung flows as well as respiratory mechanics (lung compliance and lung resistance) estimated in a manner that compensates for elastic and inelastic leaks from the ventilation system.

Leak-Compensated Respiratory Mechanics Estimation In Medical Ventilators

View page
US Patent:
8424521, Apr 23, 2013
Filed:
Feb 27, 2009
Appl. No.:
12/395332
Inventors:
Mehdi M. Jafari - Laguna Hills CA, US
Rhomere S. Jimenez - Winchester CA, US
Gail F. Upham - Fallbrook CA, US
Jeffrey K. Aviano - Escondido CA, US
Assignee:
Covidien LP - Mansfield MA
International Classification:
F16K 31/02
US Classification:
12820421, 12820222
Abstract:
This disclosure describes systems and methods for compensating for leakage when determining the respiratory mechanics of a patient during delivery of gas from a medical ventilator to a patient. The systems and methods include monitoring an instantaneous flow in the ventilation system based on one or more measurements of pressure and flow in ventilation system. The leakage is modeled using a predetermined leakage model. A leak-compensated instantaneous lung flow of gas inhaled or exhaled by the patient is estimated. Using the leak-compensated lung flow and a predetermined respiratory mechanics model, the respiratory mechanics of a patient may be estimated including at least one of a leak-compensated lung compliance and a leak-compensated lung resistance. The method may include using a dynamic respiratory mechanics model or a static respiratory mechanics model that requires use of a pause maneuver to collect the necessary data.

Flow Rate Compensation For Transient Thermal Response Of Hot-Wire Anemometers

View page
US Patent:
8434479, May 7, 2013
Filed:
Feb 27, 2009
Appl. No.:
12/394899
Inventors:
Mehdi M. Jafari - Laguna Hills CA, US
Rhomere S. Jimenez - Winchester CA, US
Edward R. McCoy - Vista CA, US
Jeffrey K. Aviano - Escondido CA, US
Assignee:
Covidien LP - Mansfield MA
International Classification:
F16K 31/02
US Classification:
12820421, 12820418, 12820423
Abstract:
Systems and methods are described for application of a transitory corrective modification to a hot-wire anemometer flow voltage and/or calculated flow rate to compensate for transient thermal response of the anemometer during a change in mixture of a mixed gas being measured. According to one embodiment a method of applying the transitory corrective modification is provided. An output signal of an exhalation flow sensor of a medical ventilator is received. The flow sensor includes a hot-wire anemometer. The output signal is indicative of a rate of flow of expired gas by a patient. Transient thermal response of the hot-wire anemometer is compensated for by applying a corrective modification to the output signal or a value based thereon. The corrective modification is based at least in part on a fraction of inspired oxygen (FiO2) being supplied by the medical ventilator to the patient.

Assignee:
Covidien LP - Mansfield MA
International Classification:
F16K 31/02
US Classification:
12820421, 12820222
Abstract:
