Clinical Scorecard: CHEST Issues OSA Guidance for Pregnancy
At a Glance
Category Detail
Condition Obstructive Sleep Apnea (OSA) Key Mechanisms Associated with hypertensive disorders, gestational diabetes, and adverse pregnancy outcomes. Target Population Pregnant individuals, particularly those with complicated pregnancies. Care Setting Clinical practice guideline for managing OSA during pregnancy.
Key Highlights
OSA affects approximately 9% of the general pregnant population. Screening for OSA is recommended using pregnancy-specific or standard instruments. Positive airway pressure (PAP) therapy is recommended for AHI > 15 events/hour. Limited evidence exists on the impact of PAP on perinatal outcomes. Postpartum reassessment is suggested for patients diagnosed with OSA during pregnancy. Guideline-Based Recommendations
Diagnosis
Screen pregnant patients for OSA using pregnancy-specific or standard screening instruments. Home testing or in-laboratory polysomnography is suggested for diagnostic evaluation. Management
PAP therapy is recommended for AHI > 15 events/hour. For AHI of 5 to 15 events/hour, treatment is suggested based on symptoms and risk factors. Monitoring & Follow-up
Monitor PAP use, adverse effects, sleep quality, and daytime functioning throughout treatment. Risks
Potential maternal and fetal risks associated with treatment decisions. Patient & Prescribing Data
Pregnant individuals with obstructive sleep apnea.
PAP adherence is noted to be low during pregnancy; shared decision-making is recommended.
Clinical Best Practices
Address sleep duration, sleep hygiene, and comorbid insomnia for residual sleepiness. Scheduled naps are suggested when feasible. Related Resources & Content
