Answer 14

Pneumograph tube
(a rubberized corrugated tube)

Question 15

✓ Once the respiratory changes are received by the pneumograph tube, they are then transmitted through the connecting rubber tubing to the recording bellows, ans with the connected lever system, powers the pneumo-pen for chart tracing and permanent recording

Answer 15

Pneumograph

Question 16

is a corrugated and stretchable rubberized tube or apparatus that is to be attached to the Subject’s chest or stomach (or both).

Answer 16

Pneumographic Tube

Question 17

Inhalation will cause the tube to stretch and subsequently create an upward tracing or movement of the pneumo-pen the polygraph chart. Exhalations are the downward tracings, thereof.

Answer 17

Pneumographic Tube

Question 18

Answer 19

CARDIOGRAPH and/or CARDIO-SPHYGMOGRAPH

Question 20

This is where the changes in blood-pressure and pulse rates are detected.

Answer 20

CARDIOGRAPH and/or CARDIO-SPHYGMOGRAPH

Question 21

When changes or impulse occur, they are received by the cuff, then transmitted through connecting tubings, then past hand-pump bulb assembly, to an aneroid sphygmo blood pressure gauge, to the recording bellows and with the connected lever system, power the cardio-pen for chart and permanent recording

Answer 21

CARDIOGRAPH and/or CARDIO-SPHYGMOGRAPH

shall be attached to the Subject's arm.

Answer 25

The Arm Cuff

Question 26

The attachment of the cuff to Subject's arm must be centered so as to produce clearer and precise Cardiographic tracings.

Answer 26
