The effectiveness of high-flow nasal cannula therapy in comparison with continuous positive airway pressure therapy in patients with obstructive sleep apnea: an open-label randomized crossover trial.

Study Objectives: Continuous positive airway pressure (CPAP) is the most effective treatment for obstructive sleep apnea (OSA). However, its effectiveness is limited by poor long-term compliance. Few recent studies have investigated the effectiveness of high-flow nasal cannula (HFNC) in treating OSA; however, its role remains uncertain.

Prevalence of poor sleep quality among physicians and nurses in a tertiary health care center.

Objectives: Sleep quality among tertiary healthcare professionals in KSA has not been well studied. Therefore, in this study, we aimed to assess sleep quality among physicians and nurses in a tertiary care center in Jeddah City and to identify the associated factors.

Methods: In this quantitative, analytical, cross-sectional study, an online, self-administered questionnaire was distributed to all physicians and nurses working at King Abdulaziz University Hospital (KAUH).

The Prevalence of Positional Obstructive Sleep Apnoea in a Sample of the Saudi Population.

Purpose: Positional obstructive sleep apnoea (POSA) is of important clinical significance, as positional treatment can augment or obviate continuous positive airway pressure. This study aimed to determine the prevalence of POSA and its characteristics using different definitions.

Methods: We retrospectively examined a cohort of patients who underwent polysomnography (PSG) between 2013 and 2019 at two sleep centres.
