Objectives The aim of the present study was to investigate the improvements of gas exchange and excessive daytime sleepiness in patients with obesity hypoventilation syndrome (OHS) in daytime and night-time split polysomnography (DSPSG and NSPSG). Materials and Methods In the present randomized controlled trial, patients with OHS were enrolled in two DSPSG (51 patients) and NSPSG (50 patients) groups in the Bamdad respiratory and sleep research center in Isfahan, Iran. In both groups, the diagnostic polysomnography (PSG) and titration were conducted in one session according to the guidelines of NSPSG. SpO2, PaCO2, and the Epworth Sleepiness Scale (ESS), were measured initially and 12 weeks after treatment. Furthermore, the PSG parameters and the type of treatments for the two groups were recorded and analyzed. Results A total of 101 OHS patients (age: 62.02 ± 12.4 year old; 61 females [60.4%]) were evaluated. There were no significant differences regarding BMI, gender, and AHI between groups (p > 0.05). Primary SpO2, PaCO2, and ESS were not significantly different between the two groups. After 12 weeks of treatment by continuous positive airway pressure (CPAP) or bi-level positive airway pressure (BiPAP), there were significant improvement of SpO2, PaCO2, and ESS score (p < 0.001). The amount of change of these variables was not different between groups. Among all variables, only the lower SpO2 and higher PaCO2 were associated with response to BiPAP. Discussion There were no significant differences in the number of changes of SpO2, PaCO2, and ESS by treatment in the DSPSG and NSPSG groups. Therefore, DSPSG may be considered as a valuable alternative method for the diagnosis and titration in OHS patients. Clinical Trials IRCT20170512033930N2

“…Recently, several studies, especially after the COVID-19 pandemic, assessed the efficacy of alternative titration modalities by comparing the standard method with the same alternative methods used in our study and reported near-similar results or compared it with other methods. 18,[21][22][23][24] Demographic and resource features of our region make it very difficult to use self-adjusting home therapeutic strategies as a calibration or therapeutic option.…”

Background: Patients with obstructive sleep apnea syndrome are mainly treated with continuous positive airway pressure. Polysomnography-guided full-night manual titration is the gold standard for continuous positive airway pressure titration, but it is cost-, time-, and effort-consuming. Alternative ways of titration are easier with less cost, time, and effort. In the era of the COVID-19 pandemic, the need to establish more safe strategies is increased. Aim: To choose a rapid, efficient, simple, and safe method with less effort and cost in the measurement of a suitable level of positive airway pressure in the management of obstructive sleep apnea syndrome. Methods: This study enrolled 48 adult patients who had been diagnosed with obstructive sleep apnea syndrome at our sleep unit and were candidates for treatment with continuous positive airway pressure according to AASM 2008 after exclusion of other sleep-related breathing disorders. All patients underwent both laboratory full-night manual titration and auto-titration (by Prisma20A of WEINMANN medical technology, Germany). Manual titration pressure and P95 of auto-titration were obtained and compared with calculated pressures by five predictive formulas (Miljeteig and Hoffstein, Sériès, Stradling, Loredo, and Lee). Results: Patients included in the study were 25 females (52.1%) and 23 males (47.9%) with a mean±SD of age of 49.98±10.36 years. Mean±SD of manual pressure was 10.44±2.49 cmH 2 O, P95 was 10.16±2.64 cmH 2 O, and calculated pressures by different equations were:
