    摘要： Highly sensitive devices for detecting nitric oxide and/or other gaseous analytes in gaseous samples are improved by the incorporation of a carbon monoxide scavenger in the interior of the device or in the device packaging. The release of carbon monoxide within the housing of the device by the plastic used in the construction of the housing or by anything within the device that releases carbon monoxide causes a loss in sensitivity due to competition between the carbon monoxide and the nitric oxide for the binding sites on the device sensor. The scavenger corrects this by either catalyzing the oxidation of carbon monoxide to the less competitive carbon dioxide or immobilizing the carbon monoxide by affinity-type or covalent binding. Analogous effects are achieved for analytes other than nitric oxide but that likewise encounter interference from carbon monoxide in binding to sensors.

    摘要： An apparatus and method for evaluation of hearing loss is disclosed. The apparatus and method use evoked Auditory Brainstem Responses (ABR) to determine if the subject is able to hear click stimuli that are repeatedly administered. In order to facilitate efficient differentiation of the ABR from the accompanying noise, normative data is used to detect test conditions where physiological, non-physiological, and ambient acoustic noise would interfere with the progression of test.

    摘要： A monitor for determining a patient's physical condition includes a calibration device configured to provide a calibration signal representative of a patient's physiological parameter. An exciter is positioned over a blood vessel of the patient for inducing a transmitted exciter waveform into the patient. A noninvasive sensor is positioned over the blood vessel, where the noninvasive sensor is configured to sense a hemoparameter and to generate a noninvasive sensor signal representative of the hemoparameter containing a component of a physiological parameter waveform and a component of a received exciter waveform. In this context, a hemoparameter is defined as any physiological parameter related to vessel blood such as pressure, flow, volume, velocity, blood vessel wall motion, blood vessel wall position and other related parameters. A processor is configured to determine a relationship between a property of the received exciter waveform and a property of the physiological parameter. The processor is connected to receive the calibration signal and the noninvasive sensor signal, and the processor is configured to process the calibration signal and the noninvasive sensor signal to determine the physical condition. In an exemplary embodiment, the physical condition is arterial stiffness that represents cardiovascular disease, however, many additional physical conditions can be measured and determined such as arterial elasticity, arterial thickness, arterial wall compliance and other conditions. Also, in an exemplary embodiment, the physiological parameter measured is blood pressure, however, the present invention can also be used to analyze and track other physiological parameters

    摘要： A noninvasive apparatus and method for measuring a subject's end tidal carbon monoxide concentration is disclosed, featuring the ability to (i) determine carbon monoxide concentration on a breath-by-breath basis, (ii) determine mean carbon monoxide concentration by averaging local carbon monoxide values, (iii) avoid the premature determination that an end tidal phase is over, and (iv) determine when breath variability or system variability will likely preclude accurate testing. The disclosed device and method allow for more robust determination of end tidal carbon monoxide concentration in subjects with turbulent or irregular breath patterns.
