An active scavenging system is distinguished by its use of applied suction to remove anesthetic gases from the operating room environment effectively. This system actively generates negative pressure, which helps to enhance the efficiency of gas removal, ensuring that harmful gases are adequately neutralized and do not accumulate in the surgical area.

The active nature of these systems allows them to be more responsive to changing gas concentrations, making them especially effective in managing and minimizing exposure to waste anesthetic gases. In contrast, passive systems rely solely on natural diffusion and do not actively pull gases away, which can lead to less effective gas removal and potential safety concerns in busy operating rooms.

This characteristic of utilizing applied suction is crucial for maintaining a safe working environment for both surgical personnel and patients, thus solidifying its importance in modern medical practices.
