SYSTEMS PHYSIOLOGY OF VENTILATION, ELECTRICAL ANALOGS, AND SIMULATIONS
Presented by the IEEE Rochester NY Section: https://r1.ieee.org/rochester
After a long history of Ventilator technology development, ventilators have become a key tool in helping patients recover from COVID-19. To understand ventilators it is crucial to understand the mechanics of ventilation and its impact on physiology. This understanding is essential not only in the design of ventilators but also in their proper use in preventing comorbidities during treatment and post-treatment. Diseases such a COVID-19 have a systemic impact on human Physiology, which can be aggravated by improper ventilation.
This talk discusses the physiology of ventilation from a systems point of view. It will make use of hydraulic systems, hemodynamic systems, and electrical analogs to elucidate both the ventilation process and some of its consequences on the physiology of organs such as lungs, blood, heart, and kidney. An electrical circuit simulation will demonstrate parametric sensitivities. This live demonstration will be an LTSPICE™ simulation of both a pressure controlled and a volume-controlled ventilator.
The talk will then propose some possible improvements in existing ventilators to minimize lung injuries and the resulting comorbidities.

Ram Dhurjaty of Dhurjaty Electronics Consulting, LLC
Ventilator Modeling, Design, and Engineering
See Talk Details for the Abstract.
A PDH will be available for this talk.
Biography:
Ram held senior positions in engineering and research, in medical systems, at Eastman Kodak Company, Analogic, and Bose Corporation before embarking on a full time consulting career. He was educated at IIT Bombay and Yale University and has degrees in Civil Engineering, Fluid mechanics, Electronic Instrumentation, Biomedical Engineering, and Control System Theory. Over his career, he has designed medical systems such as Patient Monitors, Defibrillators, CT scanners, Ultrasound Imaging Systems, Fetal Monitoring systems, Digital and Computed Radiography, Telemedicine, Telerehabilitation, and precision analog circuitry for medical systems. Ram and a team are developing open-source tools for designing affordable ventilators for LMICs.
He has 16 issued patents, and two pending, in the areas of medical devices and systems. He is passionate about affordable medical systems for Low and Middle-Income countries. He works closely with the Engineering World Health organization (EWH), developing medical devices for under-developed countries and is a member of the Board for the EWH organization. Ram developed a hand-cranked defibrillator to be marketed, initially, in India. Expertise in High voltage magnetics plus consulting in High Voltage transformer and X-Ray generator design are two of Ram’s additional qualifications. Professionally, Ram has previously served on the AAMI standards committees on Defibrillators and ECGs, Chair of IEEE Rochester Section, and as Member of IEEE Committee of Man and Radiation. He is currently a distinguished lecturer for the IEEE Consumer Technology Society and is a founding member of the IEEE SSIT.
