Set up the sphygmomanometer onto the subject's non-dominant arm and use the stethoscope to manually determine the blood pressure of the volunteer.  Remove the sphygmomanometer and set up the push button transducer for the volunteers dominant hand. Instruct the volunteer that the software has been preprogramed to provide randomized auditor cues. The volunteer may use the first 5 auditory cues as practice once the recording has started. Have the volunteer push the transducer as soon as they hear the auditory stimulus. Record until the volunteer has accurately responded to 10 auditory cues. Remove the push button transducer from the subject's dominant hand. Analyze their reaction time by averaging the difference between the time of stimulus and time of reaction.
