1. Scavenging System

A scavenging system must be used to remove Nitrous Oxide (N₂O) from the patient’s mask.

Exhaust ventilation of N₂O from the patient's mask should be maintained at an airflow rate of 45 LPM.

The airflow must be measured using a calibrated flow device.

The exhaust gas must be vented outdoors and must not be discharged into the room ventilation system.

2. Room Ventilation

Where possible, 100% fresh outdoor air should be used for dental operatory ventilation.

Supply and exhaust vents should be placed well apart to ensure proper air circulation.

Vent placement must prevent short-circuiting of airflow and allow effective mixing of fresh air.

3. Auxiliary Exhaust Ventilation

A local exhaust hood should be installed near the patient’s mouth.

This hood helps capture excess Nitrous Oxide (N₂O) released during breathing.
