What is the recommended maximum humidity in the cath lab?

• A. 60%
• B. 40%
• C. 80%
• D. 70%

Answer: (A)

Humidity in the cath lab is kept at a level that balances infection control with equipment and staff comfort. The upper limit is about 60% relative humidity. Keeping humidity at or below this level helps prevent condensation on sterile fields and equipment, reduces conditions that favor microbial growth, and avoids issues like fogging or moisture-related equipment problems. Humidity well above this threshold increases moisture risks and is not desirable. So, the recommended maximum is 60%.
