What is the Function of Spacers?

Published in Inhaler Accessory 2 mins read

The primary function of a spacer is to help you breathe medicines into your lungs more easily when using a pressurised metered dose inhaler (pMDI).

Understanding the Role of Spacers

Spacers are essential accessory devices, particularly for those who find it challenging to coordinate the activation of a pMDI with their breathing. They act as a holding chamber for the medicine, allowing you to inhale it at your own pace, rather than requiring perfect timing.

How Spacers Work

  • Improved Delivery: When you press your pMDI into a spacer, the medicine is released into the chamber. This allows the medication particles to slow down and become suspended, making it easier for you to inhale them deeply into your lungs.
  • Reduced Oropharyngeal Deposition: Without a spacer, a significant amount of medication can deposit in the mouth and throat, leading to side effects or less effective treatment. Spacers help reduce this, ensuring more medicine reaches the lungs where it's needed.
  • Ease of Use: Spacers simplify the technique for using pMDIs, making them more effective for a wider range of users, including children and the elderly.

Importance of Maintenance

To ensure your spacer performs optimally and you receive the full benefit of your medication, proper care and maintenance are crucial:

  • Initial Cleaning: Always clean a new spacer before its first use.
  • Regular Cleaning: Keeping your spacer clean is vital for its proper function. A well-maintained spacer ensures that medicine delivery remains consistent and effective.
  • Good Condition: Regularly check your spacer for any damage or wear. A spacer in good condition is key to getting the best from your medicines.

By using a spacer correctly and maintaining it well, you can significantly enhance the effectiveness of your pMDI treatment, helping more medicine reach your lungs for better respiratory health.
