pneu·mo·graph

(nū'mō-graf),
Generic term for any device that records respiratory excursions from movements on the body surface; for example, an impedance pneumograph, which applies the principles of impedance plethysmography to the chest.

n.
A device for recording the force and speed of chest movements during respiration.

Today's polygraph uses a variety of instruments to detect these differences, including cardiographs to measure heart rates, pneumographs to register respiratory rates, and galvanic skin electrodes to assess perspiration.
Before the invention of inductive plethysmography, impedance pneumographs and magnetometers were the only technologies available to capture respiratory data.
