Millions of people suffer from sleep disorders

Millions of people suffer from sleep disorders (Apnea, Insomnia, Hypersomnia…) in Europe, in the US, all over the world. Sleep disorders increase with age and overweight.

Diagnosing sleep disorders is difficult. Sleep exams need various data to be analyzed (breathing, saturation, electrophysiology) which require expertise and time.

Clinical validations

The automated algorithm ASEEGA® was validated first on healthy subjects, then on patients: Sleep Apnea, Insomnia, Hypersomnia, Narcolepsy, Mild Cognitive Impairments so far. ASEEGA was proven to be as reliable as an expert scorer.

Automated solutions
for the analysis of sleep

Physip has developed ASEEGA®, an automated analysis algorithm, which provides :

  • Automated sleep staging
  • Calculation of sleep parameters
  • Sleep microstructure detection
    (spindles, alpha bursts, slow waves)
  • Micro arousal detection

Automated analysis is a way to

  • Reduce time and cost of data analysis
  • Allow more sleep exams to be performed and analyzed with no other limit than the processing capacity

Frequently Asked Questions

Is the technology limited to nights recorded in a sleep laboratory?

ASEEGA® can analyse nights recorded both in a laboratory and in an outpatient setting.

How can I convert my traces to the edf format?

Most of the current polygraphs and polysomnographs provide the option to export recording files in the edf format. Please get in touch with us or with your usual partner if you need help to perform this operation.

What is special about your analysis method?

All our analysis methods share the same characteristics: they are entirely automatic, based only on the EEG and on a single EEG lead, preferably located at CzPz. Therefore, they achieve a unique compromise between performance and practicality.

What format are the results provided in?

Pdf reports are available. Results are provided as Excel reports, Matlab structure or XML files.


ASEEGA® has been validated on healthy subjects and patients, young and old, in night sleep and nap conditions. It has been used in studies on patients with various disorders (chronic insomnia, Alzheimer’s disease, Parkinson’s disease, post-traumatic syndrome, coma, etc.) and on healthy subjects in various sleep exploration situations.
