Abstract: A method for performing an inhalation using a nebulizer includes filling a reservoir with a medication fluid or connecting a medication container to a designated connecting piece; connecting a nebulizer unit to a control unit and a mouthpiece, at least temporarily activating the nebulizer unit; atomizing the medication fluid into a fine particulate aerosol which is emitted into an aerosol chamber formed by the nebulizer unit and the mouthpiece during activation of the nebulizer unit; performing the inhalation, with a user enclosing the mouthpiece with the lips and during inhalation, drawing air from outside into the aerosol chamber, where the air mixes with the aerosol, and then passes further through the mouthpiece as an air stream and into the respiratory tract and, possibly into the user's lung; measuring a pressure within the aerosol chamber and/or a flow rate through the aerosol chamber or the mouthpiece using the control unit; activating the nebulizer unit with each breath on occurrence of at least one activation criterion detected using the control unit; and deactivating the nebulizer unit with fulfilment of at least one stop criterion, wherein from a degree of fulfilment of the at least one activation and/or stop criterion, a weighted average value is formed and the inhalation is started when the weighted average value exceeds a threshold value.

Abstract: Automated methods provide leak detection that may be implemented in a respiratory treatment apparatus. In some embodiments, the detection apparatus may automatically determine and score different types of leak events during a treatment session, including, for example, continuous mouth leak events and valve-like mouth leak events. The detection methodologies may be implemented as a data analysis of a specific purpose computer or a detection device that measures a respiratory airflow or a respiratory treatment apparatus that provides a respiratory treatment regime based on the detected leak. In some embodiments, the leak detector may determine and report a leak severity index. Such an index may combine data that quantifies different types of leak events.

Abstract: The present invention provides for an improved method of determining a water out condition in a humidified gases supply apparatus. The method includes a two step process including a primary determination of a water out condition and a secondary determination of a water out condition. This primary determination is made during observation of the normal operation of the apparatus. During the secondary determination the method takes temporary control over the humidifying part of the apparatus. The secondary determination confirms or contradicts the primary determination.

Abstract: Apparatus and methods provide compliance management tools such as for respiratory pressure therapy. In some versions, a respiratory pressure therapy system may include one or more processors, such as of a data server, configured to communicate with a computing device and/or a respiratory pressure therapy device. The respiratory pressure therapy device may be configured to deliver respiratory pressure therapy to a patient for a session. The computing device may be associated with the patient. The processor(s) may be further configured to compute a therapy quality indicator of the session from usage data relating to the session. The therapy quality indicator may be a number derived from contributions of a plurality of usage variables for the session in the usage data. The processor(s) may be further configured to present, such as by transmitting, the therapy quality indicator to the computing device. The therapy quality indicator may promote patient compliance.

Abstract: A nasal cannula arrangement for use as part of systems for delivery respiratory gases to a patient is disclosed. The nasal cannula arrangement includes a manifold part adapted to receive gases from a delivery conduit. The manifold includes one but preferably a pair of prongs extending upward and curving towards the rear of the manifold. The prongs are inserted into the nostrils of the patient and deliver gases to a patient. The prongs have a cut out on the rear side of the prongs. The cut out forms a gases outlet in the prongs and are shaped such that the area of the cut out area is greater than the cross sectional area of the prongs at the entry point to the prongs.

Abstract: The invention is related to ventilation apparatuses and methods for operating a ventilator of a ventilator apparatus. In the method at least one duration ratio factor is set in a computing system of the ventilator apparatus; at least one minute volume, at least one functional dead space volume and at least one time constant are determined; a respiration frequency is computed, based on a previously defined lung model, depending on the determined parameters. The computed respiration frequency is optimized on at least one minimum of a delivered parameter, which is induced to a patient using the ventilator; an inspiratory time and an expiratory time are determined based on the computed respiration frequency and the duration ratio factor; at least one tidal volume based on the previously computed respiration frequency and the determined minute volume is computed; and a delivered respiratory parameter of the ventilator is closed loop controlled.

Abstract: A respiratory treatment apparatus provides respiratory treatment with improved power management control to permit more efficient power consumption and power supply units, such as battery powered operation. In one embodiment, power management prioritizes the flow generator (104) over other accessories such as the heating elements (111, 135) of a humidifier (112) and/or a delivery tube. The flow generator may control operations of the heating elements as a function of a detected respiratory cycle. For example, the timing of operation of the heating elements may be interleaved with the portion of an inspiratory phase of the respiratory cycle to permit the flow generator to operate during a peak power operation without a power drain or with a lower power drain from these components. Operations of distinct sets of components of the system (e.g., different heating elements) may also be interleaved to prevent simultaneous peak power operations.
