Abstract
This study examined the impact of background carbon dioxide (CO2) concentration on CO2 emission rates from humans. Twelve volunteers (nine males and three females) stayed in a small chamber. Three background CO2 concentration conditions determined by two different schemes: controlling ventilation rate and dosing pure CO2, were examined: 800, 1400, and 3000ppm. Indirect calorimetry was used to measure CO2 emission rates and additionally respiratory parameters. Increasing the background CO2 concentration from 800 ppm to 1400 ppm and 3000 ppm significantly reduced the CO2 emission rate.
