Abstract

Abstract

In order to study life support techniques in a confined space, seven cases were examined with four test personnel living a confined space. The test data of oxygen consumption and carbon dioxide production were obtained under different active states, and the respiratory quotient of the human body in the confined space was numerically calculated.
