Your room will have a video camera so they can see what’s happening and a sound system so you’ll be able to talk with the technicians. Your room will have a personal bathroom; just let the technicians know when you need to use it so they can take off the wires connecting you to the monitoring equipment.
All the equipment and monitoring could seem uncomfortable initially. But most of the people nod off without much trouble.
Equipment used
A technician puts sticky surface electrodes on your face, scalp, chest, and limbs. These send electrical signals, generated by your brain and muscle activity, to the measuring equipment. While you sleep, these signals digitally record your brain activity, pulse rate, cardiac rhythm, and blood pressure.
