This episode looks at obstructive sleep apnea and why diagnosis and management need scalable models of care. Professor Eddie Maloney speaks about how home sleep studies, hospital-based polysomnography, smartwatches, and remote pathways fit together in real clinical practice. The discussion includes when home testing is enough, when a full sleep lab study is still needed, and how treatment is evolving beyond CPAP to include positional devices, mandibular advancement devices, weight loss therapies, and future oral agents.
- The clinical definition of obstructive sleep apnea and why its true prevalence is likely substantially underrecognised
- The key symptom profile and collateral history that should raise pre-test probability, including snoring, witnessed apneas, daytime sleepiness, nocturnal choking, and drowsy driving
- Where home sleep testing is appropriate, and why a negative result does not always exclude OSA when clinical suspicion remains high
- The limitations of home studies versus in-laboratory polysomnography for assessing sleep architecture, complex comorbidity, central sleep apnea, and non-respiratory sleep disorders
- The evolving treatment landscape, including CPAP, positional therapy, mandibular advancement devices, hypoglossal nerve stimulation, and emerging obesity-targeted therapies
- The move toward scalable, remote, and AI-supported sleep care pathways, with ongoing emphasis on adherence monitoring and individualized follow-up
Professor Eddie Moloney is a Consultant Respiratory and Sleep Physician at Tallaght University Hospital and Beacon Hospital, with over 20 years’ experience in respiratory, sleep and general internal medicine. He has held senior clinical and leadership roles in Ireland and the UK, including as current president of the Irish Thoracic Society and has made significant contributions to respiratory and sleep medicine through research, education and professional leadership.
Outside of medicine, Eddie is a passionate tennis player and advocate for an active lifestyle.
Dr Margaret Higgins is a third year respiratory trainee at the Mater Hospital. A graduate of University College Dublin, she is currently completing a Masters at University College Cork. She is the current ITS education co-officer with a keen interest in Medical Education. Her research interests include Pulmonary Hypertension and Interstitial Lung Disease.
Dr Sandra Green is an Irish-trained respiratory fellow with a strong track record in climate advocacy and multidisciplinary sustainable initiatives, as co-founder of Irish Doctors for the Environment. She has an MSc in Leadership and Innovation in Healthcare at the Royal College of Surgeons Ireland (2023–2025). With Marisssa, she co-founded the Irish Thoracic Society Podcast Productions, launching the platform in 2024 to share knowledge, insights, and innovations in respiratory care.
