CFAM I Cerebral Function Analyser Monitor by RDM Consultants, 1977.

The CFAM I Cerebral Function Analyser Monitor helped doctors monitor brain function during comas and surgical procedures such as heart surgery. Doctors needed to understand if, and when, a patient’s brain was at risk during the surgery. The machine produces a physical ‘readout’ of brain function on a paper graph. This was analysed. Recordings of the electrical signals of the brain are called electroencephalograms (EEGs). The machine shown is a pre-production model. It was manufactured by Devices Limited with RDM Consultants Limited in 1977. It is a direct descendant of the London Hospital Survival Predictor (see 1997-1918). This predicted whether a patient in a coma following a heart attack would survive. This machine was acquired from the Department of Electrical Engineering at the University of Hertfordshire.
