Abstract : A package of instrumentation has been assembled that can monitor the following parameters on divers; electrocardiogram, respiratory gas flow, core temperature, up to 8 skin or gas temperatures, environmental temperature and ambient pressure. The signal conditioners are carried on the diver in a stainless steel cylinder capable of operation at 1700 feet of sea water. The output of each signal conditioner is fed to a 15 channel multiplex data handling system for transmission to the surface monitoring station. All sensor inputs, power and the multiplex output are made through underwater connectors to increase the versatility of the system. The unit has been used extensively in wet and dry hyperbaric chambers as well as deep water tanks and the open sea. The data can be displayed on a strip chart recorder or analyzed on a computer based data analysis system. (Author)
