"And now, man has landed on the moon, an amazing display of modern technology."
The demand for more advanced research resulted in the development of a multi-channel, multi-purpose physiological recording with internal calibration, time marker, nonskip inking system, and other tech features
Demonstration on a patient and recording on three channels: ECG (electrical activity of the heart), respiration, and blood pressure
Physiotape cassette recorder to record physiological responses
The biofeedback system, which enables conscious control of nervous system functions
Electromagnetic bloodflow meter, with demonstration on a dog
Products in use on a subject performing a physiology experiment
An artery and nerve of a dog is exposed, and when the artery is tied and an instrument inserted, the blood pressure, heart sound, and respiration can be measured through the Physiograph
The force and contraction of a frog's leg muscle twitching can be measured
The atrium and ventricle of a turtle are connected to a Narco Biosystems myograph (a tool to record muscle contractions)
"The physiograph recording system speaks for itself. When you need instrumentation for your life science research and teaching, think of Narco Biosystems"
Presented by Narco Biosystems, a Houston-based manufacturer of healthcare technology, this 1970s industrial film reviews technological advances in electronic recording equipment like the physiograph. Life scientists and doctors use physiographs to record functions like pulse, respiration, blood pressure, brain activity, heart activity, and more. Please note, the film includes scenes of medical procedures and animal testing that may be inappropriate or upsetting to some viewers.
