The SleepImage System has the Convenience of a Consumer Wearable and Accuracy that is cleared to be Comparable to Polysomnography for Diagnosing Sleep Apnea in Children and Adults.
What is SleepImage
SleepImage is a revolutionary concept in assessing sleep quality and efficiency in adults and children and eliminates the (FNE) First Night Effect*
The SleepImage Ring is worn on a finger and has no cables or other attachments which could disturb a ‘normal night’s sleep’
*The “first night effect” (FNE) is a well-known phenomenon in polysomnographic (PSG) recordings characterised by decreased total sleep time, lower sleep efficiencies, reduction in REM sleep, and longer REM latencies on the first night of testing (Agnew, Webb, & Williams,1996). First night data are often excluded in analyses of PSG recordings because they are considered to reflect a period of adaptation that is unrepresentative of usual sleep patterns.

You will be issued with a SleepImage SQE Ring and instructions for use.
The earlier one can detect a problem the easier it is to correct it.
The Breathing Well Sleep Quality Evaluation is a simple, convenient and low cost solution to the resistance that people have to conventional sleep studies. Being low cost and non-invasive it is more likely that people will be more open to a follow up study and be able to evaluate the success of the intervention.
Studies around the world have proved that poor quality sleep in children
- affects brain development
- promotes obesity later in life
- lowers IQ and performance

Limitations of Traditional Sleep Studies
Traditional Sleep Studies often change the normal night’s sleep due to the intrusive presence of wires, cables belts and electrodes. This is known as The First Night Effect* and often produces results that are not truly indicative of a normal night’s sleep.
In children, Home Sleep Studies are not available under 12 years of age due to the probability of the cables and sensors detaching during sleep, invalidating the report.
*Because there is a significant change in what is usually a ‘normal night’s sleep’ there is something known as the First Night Effect – and this often produces results that are not truly indicative of what is happening – due to all the wires, cables, belts and other invasive attachments.
Comparison with other processes
Measure Sleep Quality
Move mouse over each topic for details
Stable sleep (High-frequency coupling; 0.1-0.5Hz) is a biomarker of stable NREM sleep, which is characterized by stable breathing, high vagal tone, a non-cyclic alternating pattern (n-CAP) on the electroencephalogram (EEG), high relative delta power, blood pressure dipping, and stable arousal threshold. This state may be considered as “effective” NREM sleep. Effective sleep enables the desirable functions of sleep, across multiple dimensions (e.g., neuronal network health, metabolic, immune etc.), such that spending periods in this state enables recovery and restoration processes.
Respiratory Disturbance Index (sRDI)
Respiratory Disturbance Index (sRDI) is intended to aid in the characterization of respiratory events during sleep in addition to AHI. While the sAHI includes events that meet the definitions of apneas and/or hypopneas for diagnosis of OSA, AHI does not include arousals that do not meet the criteria for desaturations. The RDI includes apnea- and hypopnea events and in addition arousals that are not related to desaturations but may disrupt sleep and cause sleep fragmentation (Respiratory effort-related arousals (RERA’s)) and may therefore provide information for more comprehensive evaluation of respiratory isturbances during sleep. During a PSG-study, the RDI unlike AHI, also accounts EEG-arousals from sleep that do not meet the definitions of apneas or hypopneas. As the SleepImage system is not based on recording EEG brainwaves but rather cardiovascular and respiratory parameters, where presence of RERAs is detected from changes in the autonomic nervous system reflecting changes in the sympathetic tone based on changes in heart rate acceleration (HRa) and Fragmentation (eLFCBB) without the requirement of a co-occurring oxygen desaturation of 3% or more. The sRDI, when put into the context of patient symptoms for SDB, may thus provide the clinician with additional relevant information to aid clinical evaluation of Page 12 SDB and to track treatment benefit. It is important to understand that the sRDI detects changes in sympathetic-tone, which should be treated as a non-invasive surrogate measure for EEG-arousal associated with non-desaturating hypopneas and RERA’s scored during a PSG-study.
Periodicity (elevated low frequency coupling narrow-band e-LFCNB) is a subset of low-frequency coupling, consisting of periodictype breathing patterns that may occur during NREM and/or REM and indicates sustained periods of Central Sleep Apnea (CSA)
and periodic breathing, or “physiologic” periodicity due to Periodic Leg Movements (PLM’s).
Fragmentation (elevated low frequency coupling broad-band e-LFCBB) is a subset of low-frequency coupling during NREM sleep which is an indicator of sleep pathology (e.g., pain) or disordered breathing patterns like Obstructive Sleep Apnea (OSA) and Upper Airway Resistance Syndrome (UARS).
Sleep Apnea Indicator (SAI)
Sleep Apnea Indicator (SAI) is based on detecting cardiac reaction associated with prolonged cycles of oxygen desaturation, based on Cyclic Variation of Heart Rate (CVHR) during unstable breathing (tidal volume fluctuations in breathing). During each apnea event, blood oxygen decreases and is accompanied by a physiological reaction of bradycardia and, when breathing resumes, a relative tachycardia; hypoxemia is thus reflected in the SleepImage output as SAI. CVHR can be detected during
stable sleep that often may reflect events that are typically scored as mild hypopneas but may also be triggered by other pathologies such as periodic limb movements (PLMS) or restless leg syndrome (RLS). For clinical evaluation it is important to consider both SAI that is likely to reflect apnea events that disturb sleep to lower the SQI, and CVHR that is likely to reflect milder apneas and hypopneas that may or may not disturb sleep to lower the SQI.
Unstable sleep (Low-frequency coupling; 0.01-0.1Hz) is a biomarker of unstable NREM, with exactly opposite features when compared to stable sleep: low-frequency tidal volume fluctuations, cyclic variation in heart rate, a cyclic alternating pattern
(CAP), electroencephalogram (EEG) low relative delta power, non-dipping of blood pressure and variable arousal thresholds. This state may be considered “ineffective” NREM sleep. Ineffective sleep fails to accomplish the desirable functions of healthy sleep. A subset of low-frequency coupling is termed Elevated Low-Frequency Coupling (e-LFC) and has two subsets; an indicator of Periodicity (elevated low frequency narrow band; e-LFCNB) and Fragmentation (elevated low frequency coupling broad band (e-LFCBB)
Apnea Hypopnea Index (sAHI)
Apnea Hypopnea Index (sAHI) is an automated measure of Apnea/Hypopnea events and is FDA-cleared to aid diagnosis of Sleep Disordered Breathing (SDB) in both children and adults following AASM categorization (mild, moderate, severe) as summarized in table 1. The sAHI is calculated by combining SpO2-analysis, CPC-analysis and hypoxic events that are detected through the SpO2 signal where a qualifying event is characterized by a minimum of ten (10) seconds in duration and is displayed based on: (1) both 3% and 4% oxygen desaturation (2) as “Total”, “Obstructive” and “Central” events, (3) the sAHI, like the Apnea Hypopnea Index (AHI), reports the number of paused breathing events during the sleep period calculated according to the rules set by the Academy of Sleep Medicine (AASM) guidelines for event scoring.
Sleep Quality Index (SQI)
Sleep Quality Index (SQI) is a summary index of the CPC biomarkers of sleep quality, sleep stability, fragmentation, and periodicity, and provides a meaningful unit of measure of sleep health. The SQI is displayed on a scale of 0-100 with expected values for both children and adults. The SQI is useful to track sleep health over time, whether to identify the need for further clinical investigation or to track therapy. The SQI is easily communicated and relatable to the patient or other lay persons, while at the same time being a comprehensive measure of sleep health based on clinical validation.
