What does waste anesthetic gas (WAG) refer to?

Waste anesthetic gas (WAG) refers specifically to the anesthetic vapors that are exhaled by the patient. When a patient is under anesthesia, they inhale anesthetic agents, and as they exhale, these agents are released into the environment. This makes WAG a significant concern in veterinary settings, as prolonged exposure to these gases can pose health risks to veterinary staff.

Inhalation of WAG can lead to both short-term and long-term health issues for those who are frequently in close proximity to anesthetized animals. Understanding the source of WAG is vital for implementing effective safety precautions, including proper ventilation and scavenging systems to minimize exposure for veterinary staff.

Other options do not accurately describe WAG. Anesthetic vapors that are inhaled by the anesthetist relate to the working environment but do not define waste gases. Gases used to clean the anesthesia machine are not considered anesthetic gases at all and do not fall under the category of waste anesthetic gas.
