Title: [abstract] WIRELESS TELEMETRY FOR ASSESSMENT OF DIVER THERMAL STRESS.
Author: Kuehn, LA; Higgens, R
Abstract: Two techniques of radio telemetry developed at DCIEM now make possible relatively easy determination of the thermal stress experienced by working divers in operational cold water dives or hot hyperbaric chamber exposures. The first technique is a modification of the classical temperature-radio pill concept in which a small capsule is swallowed which contains a radio transmitter emitting temperature - dependent radio signals. Decoding of these signals permits easy and accurate determination of the temperatures of the diver's core before and after dives, especially if a hand-held calibrated radio receiver is used. The principal modification in this technique has been the cheap manufacture of the 'pills', thereby permitting disposability, a concept that renders them much more attractive to the diver than would otherwise be the case. The second technique is a novel new development never before used on divers or human subjects in adverse thermal environments, namely encapsulation of the same radio transmitter circuit in a small epoxy plate or 'tab' which are situated on the diver's skin at various sites to measure skin temperatures. These tabs are reusable and are not disposable, being large enough to permit battery replacement if required. They are glued to the subject's skin with a quick-setting adhesive and are easily removed after 10-hour periods with an appropriate solvent. Use of a handheld calibrated radio receiver permits easy and quick determination of skin temperatures before and after dives by this telemetric process. Both telemetric techniques produce measurements accurate to the order of 0.1 C.
