How to interpret SleepImage Ring data
The SleepImage Ring is a device that collects physiological data during sleep through a PPG sensor. It can be worn on any finger on the left hand, with the thumb or index finger being the recommended options. The device measures six data channels: plethysmogram (PLETH), oxygen saturation (SpO2), heart/pulse rate variability, respiratory excursion, respiratory effort, and body position.
The SleepImage Ring system consists of the finger-worn recorder and the SleepImage Mobile App. The ring collects the PLETH and SpO2 data signals, while the mobile app facilitates data transfer. The data is then automatically uploaded to the SleepImage cloud-based system, where it is analysed to generate a report. The cloud-based system complies with the EU Medical Device Directive and has been cleared by the FDA for diagnosis and management of sleep disordered breathing.
To interpret the SleepImage Ring data, healthcare providers will look at the coherence and cross-spectral power of pulse rate variability and respiration derived from PLETH using the CPC technique. By combining CPC data with SpO2 data, the SleepImage Ring-based Apnea-Hypopnea Index (AHI or sAHI) is calculated. AHI is the average number of apnea and hypopnea events per hour of sleep. Apnea is defined as an airflow drop of ≥ 90% of the pre-event baseline for at least 10 seconds, while hypopnea is defined as a ≥ 30% airflow drop for at least 10 seconds, associated with either ≥ 3% oxygen desaturation or arousal. The severity of Obstructive Sleep Apnea (OSA) can then be classified based on the AHI values: mild (5 ≤ AHI < 15 events/hour), moderate (15 ≤ AHI < 30 events/hour), and severe (AHI ≥ 30 events/hour).
The SleepImage Ring data can also be used to distinguish between OSA and Central Sleep Apnea (CSA) and to identify periodicity, which may indicate Cheyne-Stokes respiration. Additionally, the device can be used by individuals who already use a CPAP machine to gather data and help their healthcare team evaluate the effectiveness of their treatment plan.
