Associate Professor-Clinical, Pulm,Allergy,Crit Care & Sleep
Sleep medicine and critical care medicine
Continuing Medical Education:
Sleep disordered breathing and cardiovascular disease:
Invitations to present in national and international venues have increased since 2010. I recently presented in a conference in Japan and was invited to a seminar in a prestigious university in Japan. In September, I will present again at the Heart failure Society of America. Other invitations are listed in the relevant “invited presentations” section.
Sleep Heart fellowship:
This is a novel educational program that targets cardiologists, sleep specialists, clinicians in the area of sleep medicine and heart failure, along with sleep laboratory technicians and administrators. The mission of this program is to disseminate knowledge of the cardiovascular consequences of sleep disordered breathing; educate practitioners about the new methods and technologies in diagnosis and treatment of sleep disordered breathing; and to introduce new care algorithms to the field of sleep medicine and cardiovascular diseases. This fellowship is communicating to clinicians in the area of cardiology and sleep medicine the novel care algorithms developed in the Ross Heart hospital, Ross Ambulatory Care Area, Cardiology subspecialties (including electrophysiology and heart failure) interest in future sessions.
Other relevant CME symposia and conferences with major involvement:
Selected CME areas and activities up to 2010 is listed below and invitations to speak in corresponding national venues are listed separately in the “Invited Presentations” section.
Chronic critical illness: I created and directed this event which focuses on a novel area that is rarely addressed in the critical care literature. This is the chronic critical illness phase. Over 100 attendees mostly physicians from Ohio were present.
