Everything You Need to Know About Using a Spacer for Better Breathing
If you or a loved one manages a respiratory condition, you have likely seen a Spacer. It might look like a simple plastic tube, but this device is one of the most effective tools in your medical arsenal. Whether you are dealing with a sudden asthma attack or managing chronic respiratory conditions, understanding how to use this tool correctly can significantly improve your quality of life.
A Spacer, also known as a valved holding chamber, is designed to make your metered dose inhaler (MDI) much more efficient. By providing a chamber for the aerosol medication to sit in, it allows you to breathe in the medicine more deeply and slowly, ensuring it reaches the small airways where it is needed most.
How a Spacer Transforms Your Treatment
The primary challenge with standard inhalers is coordination. To get the medicine into your lungs, you must press the canister and inhale at the exact same millisecond. For many, including children and seniors, this is incredibly difficult. This is where optimising drug delivery through a chamber becomes vital.
When you spray medication directly into your mouth, much of it hits the back of the throat or the tongue. This not only reduces the dose reaching your lungs but also increases the risk of side effects such as oral thrush or a hoarse voice. A Spacer slows down the particles, allowing the static charge to dissipate and the medicine to stay suspended until you are ready to inhale.
Research published in The Lancet Respiratory suggests that for many patients, using an MDI with a chamber is just as effective as using a nebuliser during an emergency, provided the inhaler technique is correct.
Who Should Use a Spacer?
While many believe these devices are only for children, experts at the NHS inhaler guide and GINA guidelines suggest that almost everyone using an MDI should consider one. It is a cornerstone of a solid respiratory wellness strategy.
- Children: Often require a mask attachment to ensure the dose is inhaled correctly without needing to seal their lips around a mouthpiece.
- Elderly patients: May struggle with the hand-breath coordination required for a standard MDI.
- Emergency situations: During an acute flare-up, a chamber makes it easier to take multiple puffs quickly.
- Preventative care: Using one with steroid inhalers reduces the amount of medicine left in the mouth, promoting better preventative medicine outcomes.
The Difference Between Inhaler Alone vs. With a Spacer
To help you understand the impact, here is a comparison of the two methods based on clinical observations and respiratory health data.
| Feature | Inhaler Alone | Inhaler + Spacer |
|---|---|---|
| Lung Deposition | Lower (approx. 10-15%) | Higher (approx. 20-30%) |
| Coordination Required | High – press and breathe simultaneously | Low – press first, then breathe |
| Risk of Oral Thrush | Higher due to residue in the mouth | Significantly lower |
| Ease of Use for Kids | Very difficult | Very easy (with mask) |
Step-by-Step: Using Your Spacer Correctly
To ensure you are getting the full benefit of your respiratory health medication, follow these simple steps. Proper comprehensive inhaler guide adherence is key to improving lung function.
- Check the device: Ensure there are no foreign objects inside the chamber and that the one-way valve is moving freely.
- Shake the inhaler: Shake your MDI well to mix the propellant and medication.
- Attach: Insert the inhaler into the hole at the back of the chamber.
- Breathe out: Empty your lungs as much as possible away from the device.
- Actuate: Press the inhaler once to release one puff into the Spacer.
- Inhale: Take one slow, deep breath in. Some devices will whistle if you are breathing too fast. Hold your breath for 10 seconds.
- Wait: If you need a second puff, wait about 30-60 seconds before repeating.

Maintenance and Cleaning Instructions
To keep your device working effectively and prevent static charge from trapping the medicine against the walls, regular maintenance is essential. You should consult Asthma + Lung UK for visual demonstrations, but here are the basic cleaning instructions:
Clean your device once a month. Take it apart and soak it in warm, soapy water. Do not scrub the inside, as this can create scratches where medication gets stuck. Most importantly, do not use a tea towel to dry it. Let it air dry; this reduces static and ensures better lung deposition. For more general medication safety tips, always check the manufacturer’s leaflet.
Common Mistakes to Avoid
Even with a Spacer, errors can happen. Common mistakes include:
- Multiple puffs at once: Only ever fire one puff into the chamber at a time. Multiple puffs cause the medication particles to collide and fall to the bottom.
- Waiting too long: Inhale immediately after pressing the inhaler. The medicine only stays suspended for a few seconds.
- Forgetting to wash it: A dirty device can harbour bacteria and decrease the effectiveness of the aerosol medication.
If you are experiencing symptoms despite correct use, you may need to recognise asthma symptoms that require a medication adjustment with your GP. You can also look into deep breathing exercises to complement your medical treatment.
Understanding Different Types of Spacers
There is no “one size fits all” when it comes to respiratory tools. The Mayo Clinic highlights various designs tailored to specific needs:
Small Volume Chambers: Often used for children as they require less breath effort to clear the chamber. They frequently come with a mask attachment for toddlers.
Large Volume Chambers: These provide more space for the medicine to expand, which can be beneficial for adults managing COPD management strategies or bronchitis relief.
Before purchasing, it is wise to consult the NICE Asthma guidance or speak with your pharmacist to ensure the device is compatible with your specific brand of inhaler.
Summary
Incorporating a Spacer into your daily routine is one of the simplest ways to enhance your respiratory health. It removes the stress of coordination, reduces the risk of side effects like oral thrush, and ensures that the maximum amount of medicine reaches your lungs. Whether you are dealing with common allergy triggers or a long-term condition, this simple tool is a game-changer.

Frequently Asked Questions (FAQs)
Do I still need to wash my mouth after using a spacer?
Yes. Even though a Spacer significantly reduces the amount of medication that sticks to your mouth and throat, it is still recommended to rinse your mouth or brush your teeth after using a steroid inhaler to prevent oral thrush. This is a vital part of medication safety.
Can I use any spacer with any inhaler?
Not necessarily. While many are universal, some metered dose inhaler brands have unique shapes that require specific chambers. Always check compatibility on sites like Asthma Canada or ask your healthcare provider.
How often should I replace my spacer?
Most manufacturers and health organisations like the CDC recommend replacing your device every 12 months. Over time, the plastic can degrade and the one-way valve may become less effective, hindering your optimising drug delivery efforts.
Is a spacer better than a nebuliser?
According to a Cochrane review, for most people during an asthma attack, using a chamber with an MDI is just as effective as a nebuliser and often has fewer side effects, such as a racing heart. For more on this, visit WHO Asthma facts or Healthline Asthma.
