Does Measurement Site Matter? A Comparison Between Finger, Forehead, and Toe Pulse Oximetry Measurements in Polysomnography

Journal of Sleep Research, EarlyView.
ABSTRACT Accurate peripheral blood oxygen saturation (SpO2) measurements are critical for evaluating sleep patients, particularly those with frequent desaturations due to pathological breathing events. We compared synchronised SpO2 measurements obtained from three anatomical sites (finger, forehead and toe) in patients undergoing routine Type 1 ...

The Relative Contributions of Arousal Presence and Arousal Intensity to Post‐Respiratory‐Event Ventilation in Obstructive Sleep Apnea

Journal of Sleep Research, EarlyView.
In obstructive sleep apnea, the breathing after each obstructive event is affected by cortical arousal. Across two cohorts (N = 1781 and N = 67), arousal presence raised post‐event ventilation by 17–30%Eupnea, with each intensity step adding 1–4%Eupnea, independent of chemoreflex drive.

A Multimodal Machine Learning Model for Framingham Risk Score–Based Cardiovascular Risk Stratification in Patients With Obstructive Sleep Apnea

Journal of Sleep Research, EarlyView.
ABSTRACT Machine learning provides a powerful tool to capture complex, nonlinear patterns in biomedical data and enhance precision risk stratification. In this study, we applied a multilayer perceptron (MLP) framework to classify Framingham Risk Score–based cardiovascular risk categories in patients with obstructive sleep apnea (OSA).

The Effects of Nasal and Multi‐Level Upper Airway Surgery on Upper Airway Collapsibility and Non‐Anatomical Endotypes in People With Obstructive Sleep Apnoea—A Pilot Study

Journal of Sleep Research, EarlyView.
ABSTRACT Nasal breathing is the preferred route of breathing during sleep. Indeed, nasal blockage can cause obstructive sleep apnoea (OSA) in otherwise healthy people. Whilst multi‐level pharyngeal surgery reduces OSA severity, efficacy varies and changes in OSA pathophysiology post‐surgery have not been well characterised.

Risk Factors for Motor Vehicle Accidents in Obstructive Sleep Apnoea Patients With Long‐Term Continuous Positive Airway Pressure Therapy

Journal of Sleep Research, EarlyView.
ABSTRACT In this study, we aim to establish risk factors for sleepiness while driving, motor‐vehicle accidents and near miss incidents in obstructive sleep apnoea patients with long‐term continuous positive airway pressure (CPAP) therapy. We performed a cross‐sectional study on 1327 consecutive CPAP‐treated obstructive sleep apnoea (OSA) patients who ...

Does Hypoxic Burden Better Explain Sex Differences in Functional Impairments Than Apnoea‐Hypopnoea Index in Obstructive Sleep Apnoea?

Journal of Sleep Research, EarlyView.
ABSTRACT Women with obstructive sleep apnoea (OSA) report more severe functional impairments than men, despite lower apnoea‐hypopnoea index (AHI) values. This raises questions about the adequacy of AHI for capturing OSA severity. We explored sex differences in functional outcomes in OSA patients and examined whether AHI or hypoxic burden (HB) better ...
