title: A human breathing simulator designed to test the life support system of a hyperbaric tent.
abstract: A self contained life support system which can maintain a breathable atmosphere for up to eight hours was recently developed for use with a portable hyperbaric tent. To facilitate further life support system studies, the practicality of a human breathing simulator (HBS), which would remove oxygen and release carbon dioxide at the same rate as a human, was tested. The HBS consists of a cylinder of carbon dioxide bled into the chamber via a flow regulator and a Vanadous bubbler to chemically remove oxygen from the chamber. First experiments show that the HBS works, but that a larger chemical system is needed to remove oxygen at the desired rate. Scale up calculations have been completed.
