Recommendations include routinely inspect and maintain medical gas and vacuum systems, use filters on medical gas outlets only as a temporary measure to protect patients and devices against particles, bacteria, or liquid water found in the system, use suction canisters for any suctioning procedure, and use smoke evacuators instead of the central vacuum system for smoke evacuation during most procedures. Note that filters will not remove water vapor or other gases, which can damage some medical devices.
