摘要： A respiratory therapy system is configured to supply breathing gases to a patient and comprises a controller configured to control the pressure of breathable gas delivered to the patient. The system can control the flow of breathable gas to the patient taking into account whether or not a breath is detected, and whether or not the patient is awake or asleep. The system is configured to: detect when the patient is inhaling and to control the flow generator to deliver breathable gas at an inspiration pressure (IPAP), detect when the patient is exhaling and to control the flow generator to deliver breathable gas at an expiration pressure (EPAP), the EPAP being lower than the IPAP, and detect when the patient is at least one of awake and/or asleep. The system is also configured to receive or generate a back-up time related variable which is compared with a time related variable of at least a portion of a breath of the patient such that the breathable gas delivered to the patient is automatically controlled at IPAP, if inspiration is not detected in accordance with the back-up time related variable. The back-up time related variable may be a rate or duration for example. The delivery of breathable gas to the patient is further controlled if inspiration is not detected in accordance with the back-up time related variable and the system detects that the patient is awake. For example, if the patient is awake, the system may not automatically switch to IPAP, even if a breath is not detected within a predetermined time.

摘要： The present invention provides a respiratory adapter for inhaled media deposition in the lungs and airways. The respiratory adapter provides an inspiratory arm and an expiratory arm, wherein the two arms are joined by a bypass flow bridge. A system of valves, such as one-way valves, directs the flow of gas and media through the respiratory adapter to improve media deposition efficiency and to prevent re-breathing of exhaled gas.

摘要： An anesthesia ventilator, for the automated ventilation of a patient, includes an expiratory port and an inspiratory port for connecting a patient ventilation tube for a breathing gas, a breathing gas delivery unit, a breathing gas volume flow sensor, a breathing gas sensor for detecting a carbon dioxide concentration, a pressure sensor for detecting a pressure of the breathing gas, and a computer. The computer is configured to actuate the breathing gas delivery unit in a first mode of operation as a function of a preset ventilation rate, of the detected pressure and of a preset desired pressure value. The computer is configured to detect the presence of a desired operating state concerning the automated ventilation on the basis of the detected volume flow and of the detected carbon dioxide concentration and to make possible a transition to a second mode of operation in case of detection.

摘要： The present disclosure generally relates to systems and methods for delivery of therapeutic gas to patients, in need thereof, receiving breathing gas from a high frequency ventilator using at least enhanced therapeutic gas (e.g., nitric oxide, NO, etc.) flow measurement. At least some of these enhanced therapeutic gas flow measurements can be used to address some surprising phenomenon that may, at times, occur when wild stream blending therapeutic gas into breathing gas a patient receives from a breathing circuit affiliated with a high frequency ventilator. Utilizing at least some of these enhanced therapeutic gas flow measurements the dose of therapeutic gas wild stream blended into breathing gas that the patient receives can at least be more accurate and/or under delivery of therapeutic gas into the breathing gas can be avoided and/or reduced.

摘要： An aerosol delivery system that includes an aerosol generator that aerosolizes a fluid for delivery to a patient. The aerosol generator includes a housing with a fluid chamber that fluidly communicates with a housing inlet and a housing outlet. Within the housing, the aerosol generator includes a support plate with an aperture that fluidly communicates with the housing outlet. A vibratable member couples to the support plate across the aperture. A piezoelectric actuator also couples to the support plate, and in operation expands and contracts to vibrate the vibratable member, which aerosolizes a fluid. The aerosol generator receives fluid through a fluid conduit that couples to the housing.

摘要： Various embodiments of the present disclosure provide systems, methods and devices for respiratory support. As one example, a method for respiratory support is described that includes providing a measured pressure, and calculating a net flow based on at least one measured inlet flow and measured outlet flow. A relationship between a first value related to the measured pressure, a second value related to the measured net flow and a third value related to patient effort is used to provide a prediction of patient effort. An interim value is updated based at least in part on the prediction of the patient effort, and used to help compute a patient effort. A ventilation cycle is initiated using the computed patient effort.

摘要： An EMG measuring system has a signal processing unit (8) and with at least one electrode (4) for measuring a potential difference in a muscle, a muscle fiber or in a skin area of a patient. At least one measured signal representing the potential difference is transmitted from the electrode (4) to the signal processing unit (8). Another signal, which is transmitted to the at least one external device (9), is generated in the signal processing unit (8) on the basis of this measured signal. A signal transmitted from the at least one external device (9) is processed by the signal processing unit (8) and at least one control signal is generated on the basis of this signal.
