Sleep Tool · Our Solution
How the Aegis Sleep Tool works
The tool turns a raw overnight recording into a draft report. Each stage is checked and logged, and a clinician makes the final call.
The pipeline
Five steps from recording to report
Secure intake
Studies arrive from the clinic over an encrypted connection. Every transfer is logged.
Preparation
Recordings that were split into pieces are joined. Signals recorded at different speeds are aligned to a common timeline and cut into 30-second segments, as the AASM manual specifies.
Analysis
The AI model reads the signals across the whole night, because each stage of sleep depends on what came before it. It labels each segment as wake, N1, N2, N3 or REM.
Draft report
The labels are assembled into a chart of the night with summary measures such as the apnea-hypopnea index (AHI).
Clinician review
Staff review and correct the draft. A physician signs off.
Signals
What the tool reads
A sleep study records many channels at once. The first versions focus on the brain-activity signal the scoring standard relies on most. Further channels are added as validation proceeds.
EEG · brain activity
Separates wake from light sleep, deep sleep and REM.
EOG · eye movement
Helps identify REM sleep.
EMG · muscle tone
Supports REM identification and arousal detection.
ECG · heart rhythm
Relates cardiac rhythm to breathing events such as apnea.
Signal quality
Clean data first
Sleep recordings pick up electrical interference and movement. The engineering team has done this kind of work before, separating real signal from interference in national weather radar data. The same approach is applied to physiological recordings before the AI model sees them.
Each stage keeps a record of what was done to the data, so a result can be traced back to the original recording.
Deployment
Designed to keep working
The Sleep Tool runs on the Aegis edge and mesh architecture. Analysis can run close to the clinic, and sites can connect to each other as well as to the central cloud. The goal is that scoring continues when an internet connection is slow or lost.
Data is stored and processed in a secured, SOC-certified environment. See Security & Compliance.
Intended use
The Aegis Sleep Tool is not currently offered for independent commercial diagnostic use. It is limited to validation, pilot evaluation and investigational research while Health Canada MDEL and FDA requirements are completed.
Questions
Technical questions
What data does the Aegis Sleep Tool need?+
A complete overnight polysomnography recording from the clinic's sleep equipment. The scoring standard relies most on brain activity (EEG), and the tool is designed to use eye (EOG), muscle (EMG) and heart (ECG) signals as validation progresses.
What does the Sleep Tool output?+
A draft report with the sleep stage for each 30-second segment, a chart of the night, and summary measures, for clinician review and physician sign-off.
Can the Sleep Tool connect to our existing systems?+
It is designed to fit existing clinic workflows and to exchange results using healthcare standards such as HL7 and FHIR. Integration details are agreed with each clinic.
