Figure 5: Example 1 Calculating SCFM
After interviewing the hospital engineer, you find that the facility; which is located 2,000 feet above sea level, has 5
minor Operating Rooms, 6 ICU Ventilators, 18 ICU Beds, and 12 Recovery beds. They also want to have a 25% future
expansion. Calculate the total PCL for the facilities Medical Air system.
1. Based on the typical ventilator requirements for “specific ventilator requirements”, check with
ventilator manufacturer.
2. If the number of ventilators in the hospital is unknown, allow one ventilator per bed for 75% of the
available ICU/NICU beds.
3. The ICU area has 18 beds and 6 ventilators. The flow required for the ventilators supersedes that of
the ICU beds, so only 12 of the ICU beds are counted and added to the 6 ventilator requirements
when determining total facility requirements.
NOTE: **TO convert SCFM to LPM, multiply by 28.3
4. After reviewing Figure 5 for a capacity of 52.7 SCFM, the correct sized system would be a
duplex 15 HP system.
