A device and method is provided for electrically stimulating the diaphragm to control breathing while inhibiting respiratory drive. A stimulation phase is identified. The stimulation phase is a period of time within the breathing cycle in which stimulation will inhibit respiratory drive. The respiratory drive inhibition may be used in a number of applications including but not limited to: improving or remodeling the heart in heart failure patients, treating apnea, chronic obstructive pulmonary disorder (COPD), and hypertension.

A continuous high-frequency oscillation breathing device delivers therapy during both inhalation and exhalation in order to assist in clearing secretions from the lungs. A fixed shrouded-venturi patient interface circuit is combined with medicated aerosol to deliver continuous high-frequency oscillation therapy. Fixed open apertures in the patient interface circuit allow ingress and egress of flow, and are calibrated to allow exhalation and prevent stacking of successive breaths.

An approach to providing disordered breathing therapy involves the use of a plurality of therapy devices to deliver a coordinated disordered breathing therapy regimen to the patient. The plurality of disordered breathing devices includes at least a therapy device that delivers an electrical stimulation therapy modulating a patient's baroreflex response. Other therapy devices may include a cardiac electrical stimulation device, an external respiratory therapy device, and/or other therapy devices used in the treatment of disordered breathing. A therapy controller coordinates the therapies delivered by the plurality of therapy devices.

An external respiratory therapy device incorporates sensors that may be used to sense physiological conditions or parameters associated with pulmonary disease. The sensed conditions may be used to detect and/or to assess a presence of various types of pulmonary diseases. The assessment of the pulmonary disease may be utilized to control a drug therapy delivered to the patient to treat the pulmonary disease.

A respiratory therapy device including a housing and an interrupter valve assembly. The housing is sized for handling by a patient and defines a patient breathing passage extending from a patient end and through which a patient inhales and exhales air. The interrupter valve assembly is carried by the housing and includes a control port, a valve body, and a drive mechanism. Expiratory airflow is released from the patient breathing passage through the control port. The valve body is sized to at least partially obstruct fluid flow through the control port. The drive mechanism moves the valve body relative to the control port in response to the expiratory airflow such that the valve body repeatedly transitions between a position of maximum obstruction and a position of minimum obstruction relative to the control port to create an oscillatory positive expiratory pressure effect.

Methods and systems for diagnosing disorders, including, for example, disordered breathing, involve sensing one or more of a blood chemistry parameter and/or an expired gas parameter, such as expired respiratory gas concentration, blood gas concentration, and blood pH. Diagnosis of the disorder may be performed by a medical device, such as a respiratory therapy device or a cardiac therapy device, based on implantably detected blood gas/pH concentration/level or externally detected expired respiratory gas concentration. Cardiac and respiratory therapies for addressing the disorder may be adjusted based on the detected parameters.

A three-way diverter valve has a body with an input with a fitting for securing the input to the output of a flowmeter. The valve body also includes first and second outputs and a ball coupled to a control handle for rotating the ball valve to first or second positions. The ball has a passageway for supplying oxygen to either said first output or said second output. The control handle may include indicia identifying the active flow direction for the selected output.

A flow regulating valve for a respiratory treatment system is disclosed, as well as a vent arrangement comprising the flow regulating valve. The flow regulating valve may include an inlet, an outlet, and a variable conduit in fluid communication with the inlet and the outlet. The variable conduit may include a movable portion that may move to vary an impedance of the variable conduit, thereby regulating a flow rate of the air travelling through the variable conduit. Advantageously, the flow regulating valve may thus reduce wastage of air (e.g. humidified air) that is exhausted from a respiratory treatment system, while maintaining sufficient washout of air.

A method of providing a combination lung treatment therapy that is substantially uninterrupted between providing continuous positive airway pressure therapy and high-frequency therapy is disclosed. The present invention combines multiple respiratory therapies in order to facilitate the prevention and treatment of certain pulmonary diseases. The present invention also discloses a method of providing a combination lung treatment therapy that is substantially uninterrupted between providing medicated continuous positive airway pressure therapy and medicated high-frequency therapy is disclosed.

Automated methods provide a ventilation sufficiency assessment to evaluate patient respiration. In some embodiments, a ventilation histogram maybe determined from a measure of patient respiratory flow. Based on the histogram or associated ventilation data, hypoventilation or hyperventilation occurrences may be detected. For example, a kurtosis index and/or skewness index may be calculated with the data associated with the ventilation histogram and may be evaluated as an indication of hypoventilation or hyperventilation. An assessment of the number of peaks and other features of the ventilation histogram, such as in the case of a bimodal ventilation histogram, may be implemented to detect an occurrence of ventilation insufficiency or sufficiency. The detection methodologies may be implemented by a specific purpose computer, a detection device that measures a respiratory airflow or a respiratory treatment apparatus that provides a respiratory treatment regime based on the detected ventilation sufficiency.

A water chamber for a respiratory therapy apparatus has a base casing, a cover casing and a partition. The partition makes the air flows downward, turns around and then goes up to prolong the route and the time of the air passing through the water chamber. Therefore, the air can be saturated with moisture sufficiently to increase the air humidity. When the air is passing through the water chamber, the air is divided into two parts to each respectively enter a first tube and a second tube. The audio frequencies caused by the two parts of the air are changed due to a change of a cross sectional area. When the two parts of the air converge, the audio frequency is changed again. The partition makes the air in different portions of the water chamber have different audio frequencies, thereby reducing the resonance to eliminate noise.
