Study summary

During sleep, many people have times when they breathe shallowly or completely stop. If a person stops breathing for more than 10 seconds, this is called an 'apnoea'. If shallow breathing lasts for more than 10 seconds, it is called a 'hypopnoea'. If a person has these events frequently, it disrupts their sleep and they do not awake refreshed. It can also put strain on the heart, leading to cardiovascular conditions. These sleep disorders, usually called 'Sleep Apnoea', can be treated for most people using 'continuous positive airways pressure', CPAP. Current tests for sleep apnoea, usually used at home, are expensive, complicated for patients to use and do not monitor actual breathing. The new test, called Apne-Scan, is very simple and will cost less than the standard tests. It just requires the user to wear a mask, similar to ones used for CPAP treatment, overnight and then send the mask off for data analysis. The Apne-Scan mask, developed with taxpayer funding, is fitted with a pressure sensor to monitor actual breathing. People between the ages of 18-70 who have been referred to the sleep clinic at Royal Stoke University Hospital are eligible to participate in this exploratory study. They will wear the Apne-Scan mask at the same time as their standard overnight sleep apnoea test. The breathing data collected by Apne-Scan will be analysed by Apnea-Tech Limited, the device manufacturers, so that it can be compared to the data captured by the standard sleep apnoea test.

    Device: Apne-Scan DC1 device

Interventions

  • DeviceApne-Scan DC1 device

    The primary objective of this exploratory study is to assess Apnea-Tech's UKCA Class I Apne-Scan DC1 sleep apnoea screening device in assisting a clinical diagnosis of sleep apnoea in comparison to standard sleep apnoea test devices (ResMed NOX T3 and Phillips Alice Night One).

What researchers measure

Primary outcomes

  1. Correlation Between the Trial Device and an Established Device

    Exploratory study to look for correlation between the Apnoea Hyopopnea index (AHI) as measured by the Trial device (ApneScan) to the AHI measured by NOX T3 device (Standard Sleep home diagnostic kit). Both devices were worn concurrently overnight at home to allow for a data comparison.

    Time frame: 2 months

Secondary outcomes

  1. Severity of Sleep Apnoea

    A comparison stratified by the severity of the sleep apnoea indicated by standard sleep apnoea test devices.

    Time frame: 2 months

  2. Severity of Hypopnoea

    A comparison stratified by the severity of the hypopnoea indicated by standard sleep apnoea test devices.

    Time frame: 2 months

Other outcomes

  1. Comparison Between Sleep Apnoea Devices

    Comparing Apnea-Tech's UKCA Class I Apne-Scan DC1 sleep apnoea screening device in assisting a clinical diagnosis of obstructive sleep apnoea in comparison to standard sleep apnoea test devices (ResMed NOX T3 and Phillips Alice Night One).
