The test is painless. There is no electricity, bright lights, bells or whistles. The only physical thing felt during the polygraph test is the pressure of the air against the skin in the blood pressure cuff. When your blood pressure is taken by a doctor, the cuff is inflated to approximately 200 mm hg. The Polygraph Examiner will inflate the cuff to approximately 70 mm hg. As the test progresses, the cuff may feel tight, however, the cuff is only inflated for three (3) to four (4) minutes. The fingers may tingle but the discomfort is brief/passing and easily managed by the examinee.
