A transportable sleep recording system.


A system for monitoring sleep, which can be used in th ward without unduly disturbing either the patient or the medical and nursing staff, is described. The system records the electroencephalogram, electro-oculogram, the basal skin resistance and the galvanic skin resistance. In addition, the delta waves of the EEG are automatically counted and a histogram of their frequency plotted. The system allows a whole night's sleep recording to be compressed into just over a metre of paper.
