This week, I’m thrilled to play an encore of the interview I had in 2013 with one of the greatest sleep physicians of our time, Dr. Christian Guilleminault from Stanford University. He first described upper airway resistance syndrome (UARS) in 1993. Along with Dr. Dement, he co-coined the term, OSAS. Sadly, he recently passed as at the age of 80. This episode is a tribute to his incredible contributions and legacy to the sleep community.
