Clinically validated diagnosis
AcuPebble SA100 automated sleep apnoea diagnosis was validated in a powered clinical trial at the NHS Royal Free London hospital.
- Validated diagnosis equivalent to ambulatory gold-standard (multi-channel polygraphy followed by manual specialist interpretation).
- Validated AHI and ODI based diagnoses for both 3% and 4% desaturation criteria with high accuracy (94% PPV, 98% NPV).
- Proven usability of the device, with 100% of the patients in the trial able to complete the test without training.
Clinical Evidence
Patient-friendly design
All aspects of AcuPebble SA100 have been designed with the patient in mind:
- Easy to use, as simple as peeling off an adhesive and putting it on.
- Non-invasive, allows patients to have a more natural sleep at home.
- No training required, avoids unnecessary trips to the clinic.

How does it work?
- The AcuPebble SA100 sensor is attached at the base of the neck to record the sounds generated by the patient’s respiratory and cardiac functions.
- The signals are transferred wirelessly to a mobile device, and then uploaded to a secure cloud platform.
- Sophisticated signal processing algorithms are applied to the signals to automatically extract the parameters used for sleep apnoea diagnosis.
- Healthcare professionals get an automatically generated full diagnosis report within minutes, accessible via a user-friendly web application.
