Diagnostics of sleep apnea

Classically, sleep apnea is diagnosed with the help of a sleep laboratory measurement. For patients, this means a night’s stay in the sleep laboratory, outside of their usual environment. There are also numerous cables that are attached to the patient in order to derive a wide variety of parameters.

For this reason, we have been working on improving outpatient diagnostics for years.

In recent years, the path in diagnostics has moved away from the recording of purely descriptive values to the recording of integrated physiological parameters such as the peripheral arterial tone (“PAT technology”). In the past, PAT technology was often viewed critically due to the fully automated evaluation mechanism. With the help of manual PAT scoring, the COMPASS study was able to demonstrate, for the first time, a sensitivity and specificity comparable to that of polysomnography, even with manual evaluation. Central respiratory disorders are also completely recorded.

This technology is very similar to a mobile outpatient sleep laboratory for use in patients at home.
