STAGE 3 – SUPPLEMENTARY ASSESSMENTSDescriptionDepending on the issues arising from the initial sleep investigations, there is scope to further identify remediation options using the following assessments 1. Sleep structure - Brain activity [BRAIN] | £1140 An at-home EEG sleep monitor that measures electrical brain activity to give insight into sleep stages such as slow wave sleep, REM, and light sleep. Consists of three easy self-applied peel-and-stick sensors placed behind each ear and back of head. 2. Sleep structure – Under mattress analyser [MATTRESS] | £360 An under-mattress sleep tracker that records heart rate, breathing, movement, sleep cycles, snoring, and sleep apnea detection. Doesn't require Wi-Fi, wearing anything, and compatible with most mattresses. 3. Blood oxygen concentration [OXYGEN] | £300 A wrist worn device that measures blood oxygenation levels and can help to identify sleep apnea. 4. Core body temperature [CORE TEMP] | £600 A small swallowable telemetric tablet (eCelsius) which measures internal core body temperature. Data from the tablet is transmitted to a small receiving dock. Gut transit time is typically 24-36hours. This can help identify circadian rhythm misalignment, slow wave sleep, and sleep quality. 5. Hormonal sampling [HORMONE] | £1140 Hormones can be extracted as saliva or blood samples and are processed in our HTA-licensed laboratory using ELISA assays. The sleep hormone melatonin and stress hormone cortisol provide information about circadian rhy |
