To monitor pressure

To capture exhaled gases

The purpose of scavenging in medical gas systems is to capture exhaled gases. This process is critical in healthcare settings, particularly in operating rooms where anesthetics are used. Scavenging systems are designed to collect and remove waste gases, such as volatile anesthetics, from the environment to prevent exposure to healthcare staff and patients. By effectively capturing these gases, scavenging helps to enhance safety and maintain air quality within surgical and procedural areas.

This focus on capturing exhaled gases ensures that the levels of anesthetic agents in the operating room are kept low, thereby reducing the risk of potential health issues related to inhalation exposure for both medical personnel and patients. The implementation of scavenging systems is a vital component in ensuring compliance with safety standards and regulations in medical gas systems.
