چکیده
Abstract Objectives Quantify the effects of head rotation and incline on obstructive sleep apnea (OSA) severity. Design Single-arm, intervention study. Setting Pulmonary specialty clinic. Case presentation Ten adults diagnosed with positional OSA ranging from 32 to 64 years age 6 females, 4 males reporting persistent daytime sleepiness health issues consistent use CPAP. Intervention Standard polysomnography a angle sensor attached forehead coaching fall asleep at various angles torso in supine non-supine positions. Measurements severity was scored according American Academy Sleep Medicine guidelines. Apnea hypopnea index (AHI) peripheral capillary oxygen (SpO 2 ) saturation were measured during each epoch unique rotation, incline, position. Results Two participants (1 no apneas 1 central apnea) excluded. Among remaining 8 participants, average reduction peak AHI 66% (range 18–88%) ≤ 20° above horizon compared > horizon. The values significantly lower than (20.0 vs 45.3, P = 0.002). Minimum SpO higher for (mean: 90.6% 84.3%, 0.03). In position, (7.1 52.1, < 0.001). not statistically significant (22.3 38.4, 0.09). Conclusion These results support further exploration maintaining position minimize desaturation patients. Trial registration Hypopnea Index Severity Versus Head Position During Sleep. ClinicalTrials.gov Identifier: NCT04086407 September 11, 2019 Registered retrospectively.

متن کاملMean apnea–hypopnea duration (but not apnea–hypopnea index) is associated with worse hypertension in patients with obstructive sleep apnea
To determine which polysomnography parameters are associated with severity of hypertension.This retrospective study collected data on all patients admitted to our urban, academic center in Beijing with hypertension who had undergone polysomnograms (PSG) and were diagnosed with obstructive sleep apnea (OSA) (apnea-hyponea index [AHI] ≥5/hour). We then compared polysomnographic parameters (AHI, o...
متن کاملPhysiopathology of obstructive sleep apnea-hypopnea syndrome.
The physiopathology of obstructive sleep apnea syndrome is multifactorial. Gender and obesity status, as well as genetic, anatomic, and hormonal factors, together with ventilatory drive, interact in a diverse manner in the physiopathology and clinical expression of the disease. Obesity is the main risk factor, since increases in body mass index, visceral fat, and neck circumference are strong p...
