Patient was educated on precautions to be exercised while using a spacer as follows:

1. Always use a spacer only with an aerosol inhaler. Never use it for dry powder inhalers.
2. Never spray more than one puff into a spacer at any time.
3. Spray the medication into the spacer, when you are ready to use the device.
4. Pay attention to the sound of a whistle, if your spacer has one. You hear the whistle sound, when the technique of breathing in is inappropriate. Slow down on your breath, if you hear the whistle.
5. Spacers are to be replaced once every 6 – 12 months or as needed, if the function of spacer is compromised.
