Question 1

What minimum number of total air changes per hour (ACH) is required for general operating rooms per FGI Guidelines?

Accepted Answer

20 ACH

Answer

FGI Guidelines require a minimum of 20 total air changes per hour for operating rooms, with at least 4 of those changes being outside air, to dilute airborne contaminants.

Question 2

What air pressure relationship is required in an operating room relative to adjacent spaces?

Accepted Answer

Positive pressure to prevent corridor air from entering

Answer

Operating rooms require positive air pressure relative to adjacent spaces so that clean filtered air flows outward, preventing contaminated corridor air from entering the sterile environment.

Question 3

Which spaces in a healthcare facility require negative air pressure relationships?

Accepted Answer

Airborne infection isolation rooms and soiled utility areas

Answer

Airborne infection isolation (AII) rooms require negative pressure to contain infectious airborne particles within the room and prevent their spread to adjacent patient care areas.

Question 4

What does HEPA stand for in the context of healthcare HVAC filtration systems?

Accepted Answer

High Efficiency Particulate Air

Answer

HEPA (High Efficiency Particulate Air) filters remove at least 99.97% of particles 0.3 microns or larger, providing critical protection against airborne pathogens in sensitive healthcare spaces.

Question 5

Why is humidity control critical in healthcare facility HVAC design?

Accepted Answer

To prevent microbial growth, static electricity, and equipment damage that affect patient safety

Answer

Humidity control in healthcare facilities prevents microbial growth from excess moisture, eliminates static electricity risks, protects sensitive equipment, and maintains patient safety and comfort.
