title: Continuous 30-day measurements utilizing the monkey metabolism pod.
abstract: We have previously described a fibreglass pod system which makes possible quantitative physiological measurements to study the effects of weightlessness on 10-14-kg adult monkeys maintained in comfortable restraint under space flight conditions. Recent improvements in the system have allowed continuous measurements to be made of respiratory gas exchange, cardiovascular function, and mineral balance for periods of up to 30 days on pig-tailed monkeys. It has also been possible to operate two pods which share one set of instrumentation, thereby permitting simultaneous measurements to be made on two animals by commutating signal outputs from the pods. In principle, more than two pods could be operated in this fashion. The system is compatible with Spacelab design. Representative physiological data from ground tests of' the system are presented.
