Sleep-Related Hypoventilations
Resources for Patients and Caregivers
Sleep-related hypoventilation describes breathing that is too slow or shallow during sleep. The first signs of hypoventilation typically occur during sleep because when we’re awake, our brain can play a more active role5 in regulating our breathing.

- Feasibility of Expedited Home Sleep Testing Before Surgery for Detection of High-Risk Sleep-Related Breathing Disordersby Mehraneh Khalighi on June 6, 2025
Background: Sleep-related breathing disorders (SRBDs) are associated with perioperative morbidity. Guidelines recommend preoperative screening for SRBDs, but testing is rarely completed before surgery. We aimed to address this gap by expediting preoperative home sleep apnea testing (HSAT) among persons with suspected SRBDs. Methods: We developed an expedited referral pathway for preoperative HSAT in a subset of persons with high-risk SRBDs (HR-SRBDs) (ie, obesity hypoventilation syndrome and...
- Bicarbonate from arterial blood gas analysis as predictor of sleep-related hypoventilation: a diagnostic accuracy studyby Sanja Pocrncic on June 1, 2025
CONCLUSIONS: The sensitivity of elevated bicarbonate from awake arterial blood gas analysis using common cut-off values such as 27 mmol/L is only moderate, and bicarbonate as an integral part of the assessment of sleep hypoventilation (likelihood ratio) must be interpreted in the context of other assessments. A normal bicarbonate does not rule out sleep hypoventilation.
- Staging of obesity-associated hypoventilation in patients with morbid obesity scheduled for bariatric surgeryby Aleksander Kania on April 25, 2025
Background: Almost 20% of Polish citizens aged >15 years are obese and this number is increasing. Numerous obesity-associated diseases include, quite notably, also sleep-related breathing disorders and hypoventilation. This study aimed to analyse the prevalence of obesity hypoventilation syndrome (OHS) and hypoventilation staging in a group of patients qualified for bariatric surgery within the Comprehensive Specialist Care in Bariatrics (KOS-BAR) pilot program designed and running in Poland...
- Images: Atypical resolution of sleep-related hypoventilation in congenital central hypoventilation syndromeby Michelle Yoo on March 21, 2025
Paired-like homeobox 2B gene variants cause congenital central hypoventilation syndrome (CCHS) characterized by abnormal ventilatory control necessitating lifelong assisted ventilation (AV). We report a 3-year-old female who presented with apnea, hypoxemia, hypoventilation requiring AV, and Hirschsprung's disease during infancy followed by resolution of hypoventilation. At 3 weeks, polysomnography showed obstructive and central sleep apnea, oxygen desaturations, and hypoventilation. A novel,...
