Polysomnography/Sleep Studies

This is a short video (only showing partial wire-up) from the European Respiratory Society showing what I do at night as a clinical physiologist, i.e. body measurements during sleep. A ways into the video you will see all the equipment hanging on the walls behind them which need to go on the patient. I often get asked overall how many electrodes are placed on the patient. Don't know! I've never counted them. I keep meaning to but always forget.
