What term is the rate at which air volume moves per unit time?

• A. Baseline
• B. Contaminant
• C. Cubic feet per minute (CFM)
• D. Bloodborne

Answer: (C)

The rate at which air volume moves per unit time is measured as cubic feet per minute, abbreviated as CFM. This unit describes how much air flows through a space or along a duct each minute, which is essential for assessing ventilation performance, air changes, and the effectiveness of containment in infection control. CFM helps determine whether a room receives enough supply air or exhausts air adequately to dilute and remove airborne contaminants. Baseline refers to a starting point or reference level, not a rate of air movement. Contaminant is a substance that can be present in the air and potentially cause harm. Bloodborne describes infections transmitted through the bloodstream, not a measurement of air flow.
