Calculate Air Changes per Hour (ACH) by dividing the supply airflow of 12,000 cfh by the patient room volume of 3,000 cubic feet. (12,000 cfh ÷ 3,000 cubic feet). = 4. To diagnose the room’s ACH, compare your measured 4 ACH to the code required for patient rooms (6 ACH). It is clear that additional airflow is needed in the room.
