Rick Weitzel, Ph.D.
Adjunct Faculty and Electrical Engineer

Dr. Weitzel is a Lead Engineer at Welch Allyn and Adjunct Research Faculty in the Department of Emergency Medicine in the School of Medicine. Dr. Weitzel has over 30 years of experience in the design of medical devices. At Protocol Systems he designed continuous monitoring devices whose parameters included ECG, respiration, invasive blood pressure, non-invasive blood pressure, thermistor temperature, CO2, cardiac output and SpO2. He also designed a defibrillator and a close-loop drug delivery system that performed stress test of patients in a supine position. He specialized in power supply design, digital and analog design, system design, and, is an expert in designing and testing medical devices for Electromagnetic Compatibility. At Welch Allyn he has designed Spot Monitors, IR thermometers, diagnostic ECG, Otoscopes, Ophthalmoscopes, a vision screener and a retinal camera. He has worked on several innovation projects with OHSU including foreign object removal, non- invasive dehydration detection (for which he received a patent), an endotracheal tube cuff manometer and a device that addresses mental health.
