The respiratory quotient (RQ or respiratory coefficient) is a dimensionless number used in calculations of basal metabolic rate (BMR) when estimated from carbon dioxide production. It is calculated from the ratio of carbon dioxide produced by the body to oxygen consumed by the body, when the body is in a steady state.
Personal protective equipment for IDLH conditions: pressure-demand self-contained breathing apparatus with a full facepiece. If the concentration of harmful substances is IDLH, the worker must use the most reliable respirators.
