AcqKnowledge will extract beat-by-beat systolic, diastolic and mean blood pressure data from the raw blood pressure waveform. Simultaneously, data can be collected from ECG, EOG, EMG, RSP, EDA (GSR) and SKT amplifiers. The Equation Generator can be used to algorithmically combine various channels to generate an indicator when the subject manifests a specific physiological state. Examine the startle response of beat-by-beat blood pressure along with eye blink measurements. Use AcqKnowledge to produce a short noise burst or click and direct the signal to the STM100C to drive the OUT100 headphones. Record the physiological changes in direct response to the sound burst.
