[Guidelines in Practice: The New S3 Guideline "Sleeping Disorders - Sleep-Related Abnormal Breathing"]

Area of Science:

• Sleep Medicine
• Pulmonology
• Internal Medicine

Background:

• Sleep-related breathing disorders, including central sleep apnea (CSA) and obstructive sleep apnea (OSA), are increasingly prevalent and clinically significant.
• The German Sleep Society's S3 guideline on Non-restorative sleep/Sleep disorders was updated in November 2016, revising key aspects of these conditions.
• Previous guidelines required comprehensive evaluation, but recent updates allow for streamlined diagnostics in specific cases.

Purpose of the Study:

• To summarize and comment on the significant revisions in the 2016 S3 guideline concerning sleep-related breathing disorders.
• To highlight changes in epidemiology, diagnostics, treatment, and classification of CSA and OSA.
• To provide a clinical perspective on the updated recommendations for managing these common sleep conditions.

Main Methods:

• Review and analysis of the updated S3 guideline chapter "Non-restorative sleep/Sleep disorders" from November 2016.
• Comparison of revised recommendations with previous guidelines.
• Synthesis of key changes in epidemiology, diagnostics, and therapeutics for sleep-related breathing disorders.

Main Results:

• A higher mortality rate in pregnant women with OSA is now emphasized.
• Respiratory polygraphy may suffice for OSA diagnosis in typical clinical presentations.
• Diagnostic criteria for CSA have been modified to include cases with low apnea rates.
• New treatment recommendations for CSA in patients with left ventricular dysfunction are introduced.
• Distinction between sleep-related hypoventilation and hypoxemia is clarified, with obesity hypoventilation syndrome detailed.

Conclusions:

• The updated S3 guideline introduces important changes impacting the diagnosis and management of sleep-related breathing disorders.
• Clinicians should be aware of the revised epidemiological data, diagnostic pathways, and therapeutic strategies, particularly for OSA and CSA.
• These revisions aim to improve patient care and outcomes for individuals with sleep-related breathing disorders.
