What equipment is put on the body during a sleep study or polysomnogram (PSG), and what do they do?

ANSWER

During a sleep study or polysomnogram (PSG), sticky electrodes will be put on your face, scalp, chest and limbs. They'll send electrical signals, which are generated by your brain and muscle activity, to measuring equipment. While you sleep, these signals are recorded. The sensors record your brain activity, heart rate, heart rhythm, and blood pressure.
