Inventor top-arrow

Dr. Johnson was instrumental in the development of patented medical devices to determine volumetric flow rates in biological conduits using ultrasound. Specifically, flow directed pulmonary artery catheter to determine cardiac output using a disposable Doppler ultrasound transducer.

Dr. Johnston holds five U.S. Patents. This includes a light weight portable infant restraining device for use in aircraft and automobiles, inspired by his experience as a multiengine, instrument-rated pilot and has remote experience in aircraft accident investigation.

Dr. Johnston has been listed in the Who's Who of American Inventors.
