摘要： Inhalation measurement systems and methods enable, during inhalant exposure, substantially real-time respiratory measurements of a test subject using techniques that obtain measurements of respiration directly from that test subject, instead of from inhalation chamber parameter measurements. Direct test subject respiratory measurements may be, by way of example only, impedance measurements. These respiratory measurements taken directly from the test subject may be transmitted, wirelessly for example, for processing during the course of the test to a processing system to determine a cumulative volume of inhalant inspired by the test subject. From that, a cumulative amount of inhalant (or dose) inspired by the test subject may be determined during the course of the inhalation compound test. In addition, a calibration procedure may be performed before the inhalant exposure to provide correlation needed to translate chest and/or abdominal wall expansion measurements, made during the test, into lung volume measurements.

摘要： A neural stimulation system controls the delivery of neural stimulation using a respiratory signal as a therapy feedback input. The respiratory signal is used to increase the effectiveness of the neural stimulation, such as vagal nerve stimulation, while decreasing potentially adverse side effects in respiratory functions. In one embodiment, the neural stimulation system synchronizes the delivery of the neural stimulation pulses to the respiratory cycles using a respiratory fiducial point in the respiratory signal and a delay interval. In another embodiment, the neural stimulation system detects a respiratory disorder and, in response, adjusts the delivery of the neural stimulation pulses and/or delivers a respiratory therapy treating the detected respiratory disorder.

摘要： A method embodiment comprises generating a neural stimulation signal for a neural stimulation therapy. The signal is generated during a duty cycle of a stimulation period to provide the neural stimulation therapy with an intensity at a therapy level for a portion of the duty cycle. In various embodiments, a ramp up protocol is implemented to begin the duty cycle, a ramp down protocol is implemented to end the duty cycle, or both the ramp up protocol and the ramp down protocol are implemented. The ramp up protocol includes ramping up the intensity from a non-zero first subthreshold level for the neural stimulation therapy at the beginning of the duty cycle to the therapy level. The ramp down protocol includes ramping down the intensity from the therapy intensity level to a non-zero second subthreshold level for the neural stimulation therapy at the end of the duty cycle.

摘要： Methods and devices for classifying a cardiac response to pacing involve establishing a plurality of classification windows relative to and following a pacing pulse. One or more characteristics of a cardiac signal sensed following the pacing pulse are detected within one or more particular classification windows. The characteristics may be compared to one or more references. Classification of the cardiac response may be performed based on the comparison of the one or more characteristics to the one or more references and the particular classification windows in which the one or more characteristics are detected.

摘要： A low-noise, low-power complementary metal-oxide-semiconductor (CMOS) integrated circuit common source differential amplifier is disclosed which is capable of amplifying low amplitude cardiac signals such as those produced by atrial depolarization of the heart. The amplifier has a pair of large area p-channel input field-effect transistors (FETs) biased in weak inversion. The amplifier also has active load FETs biased in the nonsaturation (linear) region by means of a varying gate terminal voltage applied by a dynamic bias circuit. The gate terminal voltage is varied to match the temperature dependence of the output conductance of the load FETs to the temperature dependence of the transconductance of the input FETs. The gate terminal voltage also sets a dc bias point which uses the nonlinearity in the load FET output conductance to cancel nonlinearity in the input FET transconductance.
