Obstructive sleep apnea (OSA) is a condition that affects millions globally, causing daytime sleepiness, lack of oxygen, and higher risks of developing cardiac issues. A new randomized control trial, called the Pavlov study, evaluated the efficacy and long-term conditioning effects of a positional therapy device for treating positional obstructive sleep apnea. Irene Cano-Pumarega, MD, PhD, Ramón y Cajal Hospital, discusses how she and her team developed the study, the initial results, and what future positional treatments for OSA could look like on this episode of the ATS Breathe Easy podcast.
