What is the difference between a Spacer and a Holding Chamber?

  • Spacer: A spacer is a device that is placed on the mouthpiece of your quick-relief inhaler. A spacer creates "space" between the mouth and the medication when it is used. This area aids in the dispersion of the drug into smaller droplets. When you breathe in your medication, the smaller droplets will migrate easier and deeper into your lungs.
  • Valved Holding Chamber: A valved holding chamber is a type of spacer that includes a one-way valve at the mouthpiece. This device does more than provide "space" between your mouth and the medicine. It also traps and holds your medication, giving you time to breathe slowly and deeply. This helps you to inhale the whole dose of medication.
