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.

Hearing evaluation device with noise detection and evaluation capability

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 repeatedly administered click stimuli. In order to optimize evaluation, the present invention uses normative data to accurately weight the auditory responses, so that evaluation will be possible in different or changing noise conditions.

Hearing evaluation device with noise-weighting capabilities

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.

End tidal breath analyzer

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 iteratively administered click stimuli. The present invention evaluates the sufficiency of the patient connections, namely earphones and electrodes, to the evaluation device. More particularly, the present invention determines if the earphones are detached or deformed, if the electrodes have been reversed, or if the electrodes have become detached.

Hearing evaluation device with patient connection evaluation capabilities

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 repeatedly administered click stimuli. In order to expedite evaluation, the present invention uses normative data to accurately predict when a subject is likely to fail the test, so that evaluation will not needlessly continue for a subject who is very unlikely to pass.
