đď¸ PODCAST DESCRIPTION
In this episode of the ASAP Pathway Podcast, Dr. Stacy welcomes one of the most respected and passionate voices in airway science: Dr. Karen Parker Davidsonâairway clinical nurse specialist, medical researcher, innovator, and widely known as âthe nose nerd.â
This conversation goes far beyond nasal breathing and into the complex physiology of nasal function, pressure regulation, neurology, gut health, posture, and sleep. Dr. Parker Davidson explains why the nose is not simply a passageway for airâbut a diagnostic organ that reflects the bodyâs overall health, adaptation, and dysfunction. Together, they unpack why widening the airway does not always equal better breathing, how pressure differentials shift throughout the body, and why nasal resistanceânot just anatomyâmust be measured objectively. From rhinomanometry and facial phenotypes to CPAP intolerance, tongue posture, orthodontic expansion, and the dangers of oversimplified treatment protocols, this episode challenges conventional thinking and calls for deeper, more individualized diagnosis.
The conversation also honors the legacy of Dr. Klaus Vogt, a pioneer in rhinology and mentor to Dr. Parker Davidson, whose work continues to shape the future of airway medicine. This is a must-listen episode for dentists, orthodontists, ENTs, sleep physicians, therapists, and patients seeking a clearer, more nuanced understanding of airway health.

đ KEY LEARNINGS The nose is not just for breathingâit is a diagnostic organ. It reflects neurological, inflammatory, postural, and systemic changes. Nasal resistance is sneaky, slow, and often invisible. Patients adapt for years before symptoms become obvious. Bigger airways do not guarantee better breathing. Function depends on pressure differentialsânot just volume. There is no universal ânormalâ for nasal resistance. Each nose is as unique as a fingerprint. The tongue cannot function properly with high nasal resistance. Tongue posture is neurologically dependent on nasal airflow. Expansion and mandibular advancement shift pressure gradients. Improvement in one area may create dysfunction elsewhere. Mouth breathing is a reflex, not a habit. It signals underlying resistance or obstruction. Objective measurements matter. Symptoms alone can mislead diagnosis and treatment planning. Over-reduction surgeries can worsen quality of life. Empty Nose Syndrome highlights the danger of âmore space = better.â Airway care must be collaborative, not siloed đ§ ASAP Pathway â Episode Chapters

What if forward head posture, chronic neck pain, morning headachesâor even the way someone sleepsâisn't simply a musculoskeletal problem? What if the body is compensating because it's trying to breathe? In this episode of the ASAP Pathway Podcast, Dr. Stacy sits down with chiropractor Dr. Kameron Smith to explore the connection between airway health, sleep, posture, pain and chiropractic care.Kameron's interest in airway began while performing Department of Transportation physicals and recognizing how many drivers were at risk for sleep apnea. Then it became personal. Despite being young, fit and not fitting the stereotypical sleep apnea patient, Kameron was experiencing fatigue, morning headaches and concerning nighttime oxygen readings. His own diagnosis changed the way he began looking at his patientsâand eventually his own daughter.Together, Dr. Stacy and Kameron discuss how forward head posture, neck tension, mouth breathing and unusual sleep positions may sometimes be clues that the body is compensating to breathe. They also explore pediatric airway screening, craniofacial growth and development, and why simply correcting posture may miss the bigger question:Why is the body compensating in the first place? Most importantly, this conversation is a call for greater collaboration between dentists, chiropractors and other airway-focused providers. Because sometimes the posture isn't the problem. It's the clue.
What if some of the most powerful tools for healing are already inside your own body? In this episode of the ASAP Pathway Podcast, Dr. Stacy sits down with Dr. Matt Bayes, a primary care sports medicine physician, non-surgical orthopedist, and regenerative medicine doctor whose work focuses on orthobiologicsâthe use of a patientâs own cells to support healing and recovery. Dr. Bayes breaks down PRP (platelet-rich plasma), stem cells, bone marrow aspiration, adipose-derived cells, and ultrasound-guided regenerative procedures in language patients and healthcare providers can understand. He explains how platelets act as important messengers in the bodyâs healing process, how stem cells participate in tissue repair, and how these therapies may be used for certain ligament, tendon, cartilage, joint, and musculoskeletal injuries. But this conversation is also about knowing when regenerative medicine isâand isnâtâthe right answer. Dr. Bayes and Dr. Stacy discuss the importance of diagnosis and case selection, including situations where surgery remains the appropriate treatment. The discussion also bridges medicine and dentistry as Dr. Stacy explores the growing role of regenerative approaches such as PRF in TMJ care and considers how her own experience with regenerative medicine is influencing the direction of her dental practice. And beneath all of it is a wonderfully simple message: Movement is medicine. Curiosity makes us better clinicians. Collaboration improves patient care. And sometimes the best way forward is to work with the healing capacity the body already possesses.
In this episode of the ASAP Pathway Podcast, Dr. Stacy sits down with Dr. Pedro Cuartas, founder of the Collaborative Airway Management Summit (CAMS) and Clinical Director of South Louisiana Dental Sleep Medicine, for a conversation about what may be one of the biggest missing pieces in airway healthcare: collaboration.
In this episode of the ASAP Pathway Podcast, Dr. Stacy sits down with dental sleep medicine expert Crystal May, Vice President of Dental Sleep Medicine at Happy Sleep, for a wide-ranging conversation about why sleep screening needs to become a routine part of healthcareâand why dentistry may be one of the best places to start.
Season Six of the ASAP Pathway Podcast starts with the three ASAP Pathway co-founders together at the table: Drs. Stacy, Tracey, and Michelleâand this one gets personal. What actually happens to womenâs sleep when hormones begin changing? Why does obstructive sleep apnea become much more prevalent in women around midlife? Why can women feel exhausted, foggy, anxious, achy, restless and simply say, âI donât feel like myself anymoreââyet still have a sleep study that doesnât look particularly alarming? And what do estrogen, progesterone, cortisol, jaw pain, clenching, TMD, airway anatomy and even heart health have to do with one another? The founders dive into the changing conversation around perimenopause and menopause, including why traditional sleep apnea screening may fail to identify many women. They discuss the limitations of relying only on oxygen desaturations and AHI, and explain RERAsârespiratory effort-related arousalsâevents that may repeatedly fragment sleep without necessarily meeting the traditional definition of apnea.
