Minute ventilation (or respiratory minute volume or minute volume) is the volume of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from a person's lungs per minute. It is an important parameter in respiratory medicine due to its relationship with blood carbon dioxide levels..

2020/12/08Once you've determined the volume of your space and have decided how quickly you will need to exchange the air in a room, you can calculate the CFM needed for your system. Start with the total volume of air (in cubic feet), divide by the exchange rate (how quickly you want to replace the air), and the result is the total CFM you need for your system.
