About this work


The London Hospital Survival Predictor predicted whether patients in a coma following heart attacks would survive. It was the forerunner to brain function monitors. It was also an early example of a neural network. Neural networks ‘learn’ from the data collected. The condition of being ‘brain dead’ was influentially described in 1968 by a Harvard University Group. It was subsequently introduced into many legal systems. The medical Royal Colleges in the UK introduced the term ‘brain stem death’ in 1976. This enabled decision as to when organ donation could be carried out. The ambitious device was never used to determine whether a patient had already died or should have life-support withdrawn. However, its invention indicated growing problems presented by intensive care, organ donation and the concept of brain death. This is the only surviving example of the device. It was made and used at The London and St Bartholomew’s Hospitals. maker: St Bartholomew's Hospital Place made: London, Greater London, England, United Kingdom
