How often to clean ultrasound equipment?

• A. Daily
• B. After every treatment
• C. Weekly
• D. Monthly

Answer: (B)

Cleaning the ultrasound equipment after every treatment is essential to prevent cross-contamination and maintain reliable performance. The transducer, cables, and any reusable gel components come into contact with the patient’s skin and fluids, so microbes can be transferred to the next user if surfaces aren’t wiped down between uses. Following manufacturer guidelines for cleaning and disinfection ensures the surface is sanitized adequately without risking device damage. Waiting days or weeks increases the chance of spreading infections and leaving residues that can affect image quality, so cleaning after each patient is the standard approach. Using approved disinfectants and handling gel properly between patients reinforces safe practice and helps meet infection-control expectations.
