Empowered Sleep Apnea: Dr. David McCarty on CPAP, Mouth Breathing & Better Sleep

Struggling with sleep apnea, poor sleep, or CPAP that doesn’t seem to fix everything? In this powerful conversation, Dr. David McCarty, author of Empowered Sleep Apnea, joins Patrick to unpack a new way of understanding and treating sleep apnea. Instead of treating sleep apnea as a simple “CPAP problem,” Dr. McCarty explains why it’s really a complex constellation of moving parts: Unstable breathing during sleep (obstructive + central sleep apnea) Mouth breathing vs nose breathing Craniofacial development (narrow palate, jaw position, tongue posture) Functional breathing and myofunctional therapy Posture, position, and lifestyle factors In this episode, you’ll learn: Why the traditional “label-based” approach (you have sleep apnea, here’s a CPAP) often fails How diagnostic thresholds (AHI, RERAs, oxygen desaturations) can miss real sleep-breathing problems The difference between obstructive sleep apnea and central sleep apnea physiology How mouth breathing at night destabilizes breathing, drops CO₂ too low, and worsens airway collapse Why nose breathing, nitric oxide, and better diaphragm recruitment can help stabilize the upper airway The role of asthma, nasal obstruction, and inflammation in worsening sleep apnea How craniofacial development, narrow jaws, and tongue posture affect airway size Why the future of sleep medicine is collaborative: medicine, dentistry, myofunctional therapy, and breathing education working together What “narrative-based medicine” means and why your personal story matters more than just your AHI score If you or someone you love has sleep apnea, snores, wakes unrefreshed, or has been told “your AHI is normal” but you still feel awful, this discussion will give you a deeper framework to understand what’s really going on — and where new solutions may come from.
