摘要： Described here are systems and methods for monitoring airflow changes in a patient's airway during a medical procedure or as a general patient monitoring tool. Doppler ultrasound signals are acquired from the tracheal wall of the patient and parameters from those Doppler ultrasound signals are compared to baseline parameters. When a threshold change is detected, an alarm can be provided to a user to indicate respiratory compromise, which can include early airway compromise or airway obstruction.

摘要： Measurement of airway resistance and/or lung compliance during non forced exhalation is performed using initial occlusion of exhalation followed by removal of the occlusion or opening of a shutter. The measurement device can use a single sensor to measure both pressure and flow. A pressure monitor can detect that exhalation is improperly forced to signal an error or to reject a pressure and flow measurement from a forced exhalation trial.

摘要： A subcutaneously implantable device includes a housing, a first prong, and a second prong. A first electrode on the first prong is configured to contact the first lung. A second electrode on the device is configured to contact the first lung or a second lung. A third electrode on the second prong is configured to contact the heart or the tissue surrounding the heart. Sensing circuitry in the housing in electrical communication with the first electrode, the second electrode, and the third electrode is configured to measure an impedance in the first lung and/or the second lung, and/or a transthoracic impedance across the first lung and the second lung through the first electrode and the second electrode, and to measure an electrical signal from the heart through the third electrode.

摘要： Lung conditions are diagnosed and optionally treated using a functional assessment catheter or a functional lung assessment and treatment catheter. A flow restrictive component is initially placed in a bronchus or lung passageway upstream from a diseased lung region. The isolated lung region is then functionally assessed through the catheter, while the flow restrictive component remains in place. If the patient is a good candidate for treatment by occlusive or restrictive treatment techniques, the flow resistive component may be left in place. If the patient is not suitable for such treatment, the flow resistive component may be removed.

摘要： A method for computing lung compliance imaging, the method comprising obtaining one or more images of lungs, determining a spatial transformation of each voxel within the lungs between the lungs at an inhale position and the lungs at an exhale position to provide displacement vector estimates for each voxel within the lungs, performing volume change inference operations to determine a volume change between the lungs at the inhale position and the lungs at the exhale position based on an inhale region of interest, an exhale region of interest, and the displacement vector estimates for each voxel within the lungs, computing a lung compliance based on the volume change inference operations.

摘要： The present invention provides a method of conducting a sleep analysis by collecting physiologic and kinetic data from a subject, preferably via a wireless in-home data acquisition system, while the subject attempts to sleep at home. The sleep analysis, including clinical and research sleep studies and cardiorespiratory studies, can be used in the diagnosis of sleeping disorders and other diseases or conditions with sleep signatures, such as Parkinson's, epilepsy, chronic heart failure, chronic obstructive pulmonary disorder, or other neurological, cardiac, pulmonary, or muscular disorders. The method of the present invention can also be used to determine if environmental factors at the subject's home are preventing restorative sleep.

摘要： Systems for evaluating the respiratory function of an individual using forced oscillation technique (FOT) oscillometry include a blower controlled so as to apply FOT pressure oscillations on top of a low amplitude offset pressure. A controller continually adjusts the rotational speed of the blower to maintain a targeted time-varying pressure profile in the breathing air provided to the patient.

摘要： Systems and methods for determining lung impedance of a subject by acquiring multiple impedance measurements from different areas of a thorax of the subject, using multiple electrical circuits, each electrical circuit comprising a pair of electrodes attached at different locations over the thorax of the subject. The acquisition of impedance measurements of all of the electrical circuits is done at the same timing-position(s) over the subject's breathing cycle. The acquired impedance measurements may be used to determine at least one physical characteristic associated with the respective subject. The electrical circuits may be powered by several generators outputting AC power at same or different frequencies. According to some embodiments, one of the electrical circuits, powered by one of the generators, may be continuously operated when measuring is done to be used as a timer.
