  • Remove port cap and position nebulizer aerosol port in an upward position.
  • Fill nebulizer through the main aerosol port with a prescribed amount of medication.

How to use Drive 646 Nebulizer?

  • It is important to be in a comfortable upright position during the treatment.

  • Attach nebulizer tubing to a mechanical compressor such as the DeVilbiss 5650, 4650, or 3655 series compressors. If compressed air or oxygen is used, set regulator to permit 5-7 lbs. pressure or a flow of 6-8 liters per minute.
