1. Scavenging System

• Use a scavenging exhaust ventilation system.

• Exhaust ventilation of N₂O (Nitrous Oxide) from the patient’s mask should be maintained at an airflow rate of 45 LPM, measured by a calibrated flow device.

• Exhaust gases must be vented outdoors and not into the room ventilation system.

2. Room Ventilation

• Wherever possible, use 100% clean outdoor air for dental operatory ventilation.

• Supply and exhaust vents should be well separated to allow proper air mixing and prevent “short-circuiting” of airflow.

3. Auxiliary Exhaust Ventilation

• A local exhaust hood should be placed near the patient’s mouth to capture excess N₂O released during breathing.
