Monitoring of the neonatal electroencephalogram using an infrared multichannel telemetry system

A 3-channel neonatal medical monitoring system is described which uses infrared light instead of electrical leads to transmit physiological signals from the neonate to monitoring equipment. This system is especially applicable to situations where low level physiological signals such as the EEG need to be monitored in the vicinity of other life support and monitoring equipment that is likely to introduce electrical interference. Examples of EEG activity showing the progress of a neonate, who had experienced asphyxia, are presented.
