Appl. No.:

11/715726

International Classification:

A61M 15/00
A61M 16/00
A62B 7/04

US Classification:

128204220, 128203140, 128204260

Abstract:

A system is provided for delivering a flow of breathing gas to an airway of a patient. The system includes a pressurizing flow module that generates a pressurized flow of breathing gas and a patient circuit coupled to the pressurizing flow module configured to communicate the flow of breathing gas to an airway of a patient. The system includes a sensor for monitoring a characteristic of a breathing pattern of the patient a controller that communicates with the sensor configured to increase a fraction of inspired carbon dioxide if the characteristic exceeds an upper threshold value and to provide servo-ventilation if the characteristic is less than a lower threshold value. The upper threshold value and the lower threshold value are changed based on the monitored characteristic of the breathing pattern of the patient.

International Classification:

A61M 16/00

US Classification:

12820423

Abstract:

A therapy system adapted to treat a patient's ventilatory instability using a ventilatory therapy, a gas modulation therapy, or both. The algorithm implemented by the therapy system monitors the ventilatory instability, such as Cheyne Stokes Respiration (CSR), mixed apneas, CPAP emergent apneas, and complex sleep disordered breathing (CSDB) and treats the ventilatory instability. The algorithm also determine a reference point with respect to the ventilatory instability. The therapy delivery system initiate the treatment based on the reference point.

International Classification:

A61B 5/00

US Classification:

600300

Abstract:

A system that determines one or more sleep phenotyping parameters of a subject. In one embodiment, the system comprises a sleep sensor, a stimulus generator, and a processor. The sleep sensor generates signals that convey information related to the physiological functions that indicate the sleep stage of the subject. The stimulus generator provides a stimulus to the subject that enables information related to the sleep phenotyping parameters to be determined. The processor receives the signals generated by the sleep sensor and is in operative communication with the stimulus generator. The processor (i) determines, based on the signals received from the sleep sensor, whether a trigger condition related to the current sleep stage of the subject is satisfied, (ii) controls the stimulus generator to provide the stimulus to the subject if the trigger condition is satisfied, and (iii) quantifies the response of the subject to the stimulus.

Appl. No.:

13/256295

Inventors:

Stephen Dalton Pittman - Brookline MA, US
Erik Kurt Witt - Murrysville PA, US

Assignee:

KONINKLIJKE PHILIPS ELECTRONICS N.V. - EINDHOVEN

International Classification:

G09B 23/28
A61M 16/00

US Classification:

434262, 12820418

Abstract:

A system and method are configured to adjust the tidal volume of the breathing of a subject. The subject is self-ventilating (breathes under her own power). The adjustment of tidal volume accomplished through use of the system and/or method may reduce hypertension (e.g., lower blood pressure), reduce stress and/or anxiety (and related maladies), improve relaxation, decrease sleep latency, improve sleep quality, address other sleep disorders, and/or provide other health benefits. The system and method are effective in adjusting tidal volume while the subject is awake and/or asleep.

International Classification:

A61B 5/085
A61B 5/08

US Classification:

600532

Abstract:

A system and method are implemented to identify pulmonary congestion in a subject. The system and method detect pulmonary congestion in a subject based on one or more parameters of the breathing of the subject. The detection of pulmonary congestion in the subject may be relatively passive for the subject. This may enhance the convenience and/or comfort of compliance to a detection regime by the subject. By detecting pulmonary congestion in the subject, potential episodes of heart failure may be identified and/or averted. The system and method may be configured to facilitate treatment of the subject to remediate detected pulmonary congestion and/or avert potential episodes of heart failure. For example, the system may provide enhanced access for a caregiver to detections of parameters related to pulmonary congestion in the subject.

International Classification:

A61M 16/00

US Classification:

12820421, 12820418

Abstract:

A pressurized flow of breathable gas is delivered to the airway of a subject through a gas circuit () as part of a therapy regime. Leakage of gas from within the circuit to atmosphere to prevent re-breathing of gas is dynamically adjusted to stabalize the total amount of leakage.

US Classification:

12820423

Abstract:

An interface appliance is configured to deliver a flow of fluid to the airway of a subject. The generation of the flow of fluid may be controlled to provide a therapeutic benefit to the subject. The interface appliance is configured to carry one or more sensors () configured to detect one or more parameters related to the flow of fluid on the subject. The one or more parameters may then be used to control the generation and/or delivery of the flow of fluid.
