Breathing rate can be measured as volume of breaths per day. Breathing rate is used in risk assessment of inhaled toxic compounds. US EPA have provided a report where they have calculated an individual's ventilation rate directly from their oxygen consumption rate. This revised approach will be used to update the ventilation rate information in the Exposure Factors Handbook, which serve as a resources for exposure assessors for calculating inhalation and other exposures.
