Monitoring of Diaphragm Position in Pulsatile Pnumatic Ventricular Assisted Device by Ultrasound Sensor (A New Method for Flow Measurement in VAD)

Autor: Hwansung Lee, Tadayuki Kamimura, Yukihide Kakuta, Tomonori Tsukiya, Yoshiyuki Taenaka, Soichiro Kitamura, Eisuke Tatsumi, Akihiko Homma

Publikováno v: JSME International Journal Series C. 47:1124-1127

A new method using ultrasound sensors to detect the diaphragm position of a ventricular assist device (VAD) was proposed. Two small ultrasound sensors of 2.4mm diameter were attached to the outside surface of blood chamber of a pneumatic VAD. The rec
