Effectiveness of Telematic Instruction to Patients in the Correct Performance of Respiratory Polygraphy at Home

Patients received a QR code and a link for access to a YouTube video recorded to this effect where the process of setting up the respiratory polygraph was explained. The contents of the video were the same as those in the face-to-face instructions. The visualization of the video was at home, and it could be viewed as many times as necessary.

A trained nurse with long experience in home sleep studies explained the setup of the respiratory polygraph. At the end of the intervention doubts about the procedure were addressed. Patients did not have access to the video.
