What is the primary purpose of a high-volume evacuator (HVE) during aerosol-generating procedures?

• A. Saliva ejector
• B. Handpiece suction only
• C. High-volume evacuator (HVE)
• D. Air purifying wand

Answer: (C)

The main idea is to capture and remove aerosols and splatter right at the source during procedures that generate them. A high-volume evacuator provides a strong, high flow of suction placed close to the area of aerosol generation (near the tooth and handpiece), so it rapidly evacuates air and particles before they disperse. This reduces the concentration of airborne contaminants around the clinician and patient, helps keep the working field clearer for better visibility, and lowers contamination of surfaces in the room.

Saliva ejectors are designed for light suction of saliva and moisture, not for high-volume aerosol control, so they’re not effective for the larger particle cloud produced during aerosol-generating procedures. Suction at the handpiece alone lacks the reach and flow needed to remove aerosols generated away from the tip. An air-purifying wand isn’t used to evacuate aerosols during the procedure; it’s more about room air handling than capturing the source plume.
