A system for studying the physiologic response of divers to hyperbaric environments

A fifteen channel hardwire, multiplexed physiologic monitoring system for use on divers in all environments is described. Parameters include ECG, respiratory gas flow, temperatures, work output and ambient pressure. The system may be used in a dual diver mode. The data may be analyzed on a computer based data acquisition system. A specially designed ergometer is described. The data will be useful in assessing man´s capabilities and limitations in the sea. Preliminary results indicate that the system described here is useful for monitoring thermal stress on divers as well as general physiologic response to imposed work loads.
