No. There will be registered sleep technologists (RPSGT’s) in a work area of the lab separate from the bedrooms with you on the night of your study. They are available if you need them! For example, you will be able to call them to disconnect your monitors if you have to go to the bathroom during the night. They may come into the room to adjust sensors if need be. Otherwise, no staff will be with you in the room while you sleep. There is no one-way glass looking into the room. Video is recorded during your sleep study for physician review after the study (if sleep talking, sleep walking, et cetera are of concern).
