The early detection and treatment of sleep apnea syndrome (SAS) is becoming an important issue in medical practice, as the conventional polysomnography-based method is not only costly, but also demands high expertise from technicians. In this study, we propose a method for diagnosing SAS using noninvasive measurements of oxygen saturation (SpO2), obtained from a pulse oximeter as the input signal, using convolutional neural networks (CNNs). As a result of 10-fold cross-validation, we confirmed that the proposed method yields an 88.99% accuracy.

Obstructive sleep apnea hypopnea syndrome (OSAHS) is a common sleep-disordered breathing condition that exhibits a notable degree of heterogeneity, a feature not fully considered in current diagnostic and therapeutic strategies. This article reviews and analyzes research progress in the subtyping of OSAHS from multiple perspectives, including clinical feature-based subtyping, comorbidity-based subtyping, polysomnography (PSG) parameter-based subtyping, and other classification approaches. Existing studies have identified common subtypes based on clinical features and clarified the characteristics of different subgroups in comorbidity-based classifications; the rich data provided by PSG have helped optimize the classification of OSAHS; and multi-dimensional clustering has provided a more precise basis for individualized treatment.

Introduction: During sedation for gastroscopy, hypoxaemia represents the most common adverse event. The objective of this trial is to assess the efficacy and safety of bilevel positive airway pressure (BPAP) for the prevention of hypoxaemia, in comparison with nasal cannula oxygen therapy, among patients predisposed to hypoxaemia during sedation for gastroscopy.
Methods And Analysis: This randomised controlled trial (RCT) will include 616 patients at risk of hypoxaemia when undergoing gastroscopy, including those with advanced age, frailty, American Society of Anesthesiologists grades III-IV, obesity, obstructive sleep apnoea-hypopnoea syndrome, cardiac disease, respiratory disease and diabetes.
