Bi-level PAP with backup rate recommendation

In this season 8 premiere of Talking Sleep, host Dr. Seema Khosla welcomes three members of the AASM guideline committee—Dr. Rami Khayat, Professor and Division Chief of Pulmonary, Allergy & Critical Care Medicine and Director of Penn State Health Sleep Services; Dr. Shirine Allam, Professor of Medicine at Emory University and Program Director for the Pulmonary and Critical Care Fellowship at the Atlanta VA Medical Center; and Dr. Christine Won, Medical Director of Yale Centers for Sleep Medicine and Professor of Medicine at Yale University—to discuss the newly released AASM clinical practice guidelines for central sleep apnea treatment.

The conversation begins with the rigorous process behind guideline development, clarifying the distinction between evidence-based recommendations and expert opinion. The panel systematically walks through each recommendation, addressing CPAP use across various CSA etiologies including primary CSA, heart failure-related CSA, medication-induced CSA, treatment-emergent CSA, and CSA due to medical conditions.

A surprising recommendation against BPAP without backup rate generates discussion about why backup rates matter and why heart failure patients are excluded from certain BPAP recommendations. The experts tackle the controversial topic of adaptive servo-ventilation (ASV), explaining why it's now conditionally recommended even for heart failure patients despite SERVE-HF trial concerns. They clarify that newer ASV algorithms differ from devices used in that study and emphasize the importance of patient-provider shared decision-making and treatment at experienced centers.

Practical implementation guidance covers oxygen therapy for heart failure and high-altitude CSA, including insurance coverage challenges. The panel discusses acetazolamide use across multiple CSA etiologies, providing concrete advice on prescribing and follow-up protocols. Transvenous phrenic nerve stimulation receives attention as an option for select patients, with candid discussion about its invasive nature, accessibility limitations, and high costs.

The episode addresses the shift toward viewing CSA treatment as chronic disease management, including billing code G211 implications. The experts emphasize that guidelines guide but don't constrain clinical judgment, stressing the importance of monitoring beyond AHI—including patient symptoms and quality of life improvements.

Whether you're treating patients with CSA, navigating insurance coverage, or seeking clarity on when ASV is appropriate, this review provides essential guidance for implementing evidence-based CSA treatment.

Join us for this season premiere that translates complex guidelines into practical clinical applications.
