Sleep Profiler™ EEG Sleep Monitor bridges the gap between laboratory polysomnography and actigraphy. Three frontopolar channels provide the EEG, EOG and EMG signal features needed to characterize by-stage sleep time. The lightweight, wireless device includes voice messages and other intuitive design features that enable reliable self-application in the home with acquisition across multiple nights.

Sleep Profiler combines web-based presentation of recorded signals with validated auto-staging and technical editing capabilities. Interpretation features include customized editing, touch-point insertion of key diagnostic and treatment recommendations, and secure signature insertion.
‍
Report formats include automated generation of medical history summaries, medication usage, comparison to age/sex normative ranges, and patient reports that contrast their sleep diary entries to the objective sleep quality measures.

Sleep Profiler RTA combines wireless transmission of the signals to a tablet with real-time sleep staging for the monitoring of sleep quality and abnormal EEG patterns in hospitalized patients or in research applications.

Features

Records EEG, EOG, EMG, with optional submental EMG or ECG, pulse rate, head position, head movement, quantitative snoring
Auto-staging accuracy equivalent to PSG-based manual staging variability with:
sleep spindles, spindle duration and power spectral densities
movement arousals, cortical arousals, microarousals and autonomic activations
sleep latency, REM latency, N3 latency

Auto-Staging Validated to PSG

Monitors study status and automatically sends reminder emails
Multi-night studies with night-to-night comparisons
Up to 30 hours of in-home recording between battery charges
Objective vs. subjective comparison report
Continuous 24/7 monitoring available for the ICU or Hospital
Available with application of novel sleep biomarkers

Applications

Clinical

Sleep Profiler enables clinicians to easily and accurately:
Differentiate short sleep syndrome from sleep state misperception
Identify abnormal sleep patterns attributed to chronic or neurodegenerative diseases
Monitor the effects of OSA therapy on sleep quality
Assess the dose-dependent medication effects on sleep architecture and sleep continuity
Sleep Profiler is ideal for multi-night or repeated measures assessment of patients complaining of symptoms consistent with:
Insomnia
Hypersomnia
Other non-OSA sleep disorders

Research

Sleep Profiler is being used by researchers to assess:
REM sleep without Atonia in patients with RBD
Prodromal sleep biomarkers for neurodegenerative disease
Effect of Suvorexant progressive supranuclear palsy
Differences between normal cognition and mild cognitive impairment, Alzheimer’s disease, Parkinson’s Dementia, and Dementia with Lewy Body
Sleep patterns in patients with ICU delirium
Effects of medication type, timing, and dosage on ICU sleep and outcomes
Sleep quality changes as a result of cannabis and opioid dependency
Outcomes resulting from an insomnia intervention
Influence of sleep deprivation on memory
