Entropy-based Physiological Signal Analysis in Patients With Obstructive Sleep Apnoea

This observational study is being undertaken as a part of a Master of Research (MRes) in Clinical Research programme. Its goal is to learn about how continuous positive airway pressure (CPAP) therapy changes the complexity of body signals in adults with obstructive sleep apnoea (OSA). The main question it aims to answer is: \- How does the complexity of physiological signals (specifically oxygen saturation, heart rate variability, and airflow) change in adults with OSA from before to after three and six months of CPAP treatment? It will use data from individuals who took part in an earlier trial, called 3DPiPPIn, which tested the use of 3D-printed, customised masks CPAP masks through sleep studies.

Sleep-disordered Breathing Database

The goal of this study is to collect clinical data on patients who have had a sleep study and are given a diagnosis of a sleep related breathing disorder such as obstructive sleep apnoea. Collecting this data in an organised way will mean that the investigators can monitor patients and their health outcomes.

Feasibility of Upper Airway Stimulation in OSA

Project Breathe 1 is a short-duration (5 month) pilot investigation to assess the safety and tolerability of non-invasive electrical stimulation in adults with obstructive sleep apnoea. The investigation is an unblinded, uncontrolled, single arm design.

A Study Assessing Adult Patients Referred to an NHS Sleep Service With Suspected Obstructive Sleep Apnoea. This Study Aims to Compare the Sunrise Wearable Diagnostic Device Performance and Potential Inclusion in a NHS Diagnostic Pathway With Oximetry and WatchPAT Which Are Currently Used.

The goal of this clinical trial is to evaluate whether the Sunrise device (that measure small jaw movements) can improve the diagnosis and management of Obstructive Sleep Apnoea (OSA) in adults (≥ 18 years) referred to a Sleep Clinic. The main question it aims to answer are: \- Does Sunrise lead to a higher proportion of definitive management decisions (initiate OSA treatment, discharge from the sleep clinic service, additional diagnostic testing required or a clinic appointment) compared to current screening practices, which includes either overnight oximetry or use of a wearable device called WatchPAT 300? Researchers will compare Sunrise results with oximetry and WatchPAT 300 outcomes to see if Sunrise improves diagnostic efficiency, reduces time to a diagnosis or clinical decision and enhances patient experience. Participants will: * Follow the standard clinical pathway (oximetry or WatchPAT 300) * Use the Sunrise device simultaneously for one night with their usual test * Complete a patient feedback questionnaire on ease of use and experience * Return all equipment two days later, Sunrise results will not affect their clinical care and will be used for the study only
