A spacer is a tube-like holding chamber designed to improve the delivery of medication from a metered-dose inhaler (MDI), commonly used for asthma or COPD treatment. Shaped like a small football or tube, it helps ensure the medication reaches deep into the lungs where it’s most effective.
By reducing the amount of medication that settles in the mouth or throat, spacers minimize irritation and the risk of mild infections. They also make it easier to coordinate pressing the puffer and inhaling simultaneously.
Who Should Use a Spacer?
Spacers are recommended for:
- Children under 5 years old, with a mask attached for better fit
- Adults using corticosteroid preventers like Flixotide or Symbicort with an MDI
- People who struggle with the “press and breathe” technique required for MDIs
- Anyone using a reliever medication, such as Ventolin, during asthma attacks
Why Choose a Spacer Over a Nebuliser?
Current research shows that using a puffer with a spacer is just as effective as a nebuliser for managing asthma symptoms, including during attacks. Additionally, spacers are:
✅ Simpler to use
✅ More affordable
✅ Portable and convenient
✅ Associated with fewer side effects
How to Choose the Right Spacer
Spacers come in various shapes and sizes. Consult your pharmacist, nurse, or asthma educator to find the best option for your needs. Choose one that’s easy to assemble and convenient for daily use.
Tips for Using a Spacer Correctly
✔️ Fire one puff at a time into the spacer.
✔️ Inhale immediately after firing a puff, as the medication can settle quickly.
For each puff, choose one of the following breathing techniques:
1️⃣ Take one deep breath – Inhale slowly and deeply, then hold your breath for about 5 seconds (recommended).
2️⃣ Breathe normally for 4 breaths – Use this method if you’re unable to take a single deep breath.
👉 Reminder: Always shake your puffer before firing each dose.
Cleaning Your Spacer
To keep your spacer hygienic and effective, clean it once a month or after recovering from any respiratory infection.
Steps to Clean a Spacer:
- Disassemble the spacer if necessary.
- Wash each part in warm water with liquid dishwashing detergent.
- Air dry the parts without rinsing – using a cloth or paper towel can cause static, which makes medication stick to the spacer walls.
- Wipe the mouthpiece if detergent residue remains.
- Reassemble once completely dry.
Note: It’s normal for spacers to appear cloudy over time, but they should never show signs of mould or discoloration.
Conclusion
Using a spacer correctly improves medication delivery, making asthma or COPD treatment more effective. By choosing the right spacer and maintaining it properly, you can enhance your breathing routine and reduce potential side effects.
