CPE Physiological Monitoring 2

Question 1

Which component of the pneumograph measures respiratory effort during a polygraph examination?

Accepted Answer

A convoluted rubber tube placed around the thorax or abdomen

Answer

The pneumograph uses a convoluted rubber tube that expands and contracts with breathing, recording thoracic and abdominal respiratory movement.

Question 2

In polygraph physiology, 'baseline' respiration is best described as:

Accepted Answer

The normal, undisturbed breathing pattern recorded before relevant questions begin

Answer

Baseline respiration represents the subject's normal breathing pattern established during neutral or irrelevant questioning, used as a reference for comparison.

Question 3

A sudden increase in electrodermal activity (EDA) most directly indicates:

Accepted Answer

Activation of eccrine sweat glands controlled by the sympathetic nervous system

Answer

EDA increases result from eccrine sweat gland secretion, which is controlled exclusively by the sympathetic nervous system and reflects arousal or stress.

Question 4

What does a 'staircase' pattern in the cardio channel of a polygraph typically suggest?

Accepted Answer

Progressive rise in relative blood pressure over successive questions

Answer

A staircase pattern reflects a stepwise rise in relative blood pressure across question presentations, often associated with psychological arousal or deceptive responses.

Question 5

During polygraph testing, 'apnea' in the pneumograph channel refers to:

Accepted Answer

A temporary cessation or suppression of breathing

Answer

Apnea is a pause or cessation of respiratory movement and is considered a significant deception indicator when it occurs at relevant questions.
