To investigate what problems occur during sleep and what causes them, a sleep study can be done. This is called a polygraph. The results of this examination can be used to make a diagnosis.

The Divi Polygraph explains to the patient what a polygraph is and exactly what is measured during the examination. A polygraphy often takes place at home. Therefore, the patient must connect the instruments himself. Therefore, this Divi also includes a short instructional video for the patient to watch.
