Videokymography is a high-speed medical imaging method to visualize the human vocal fold vibration dynamics. It was invented by Jan G. Švec under the guidance of Harm K. Schutte.
He devised the kymograph as a means of obtaining a written record of the variations in the pressure of the blood in the blood vessels; and this apparatus not only conducted him to many important conclusions respecting the mechanics of the circulation, but afforded the first instance of the use of the graphic method in physiological inquiries ...

A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs.A spirometer measures ventilation, the movement of air into and out of the lungs.
