Correct Inhaler Usage Techniques

Why Correct Inhaler Technique Matters

It's important to use your inhalers and other devices correctly to ensure you are getting the right dose of your medicine. Poor technique means less medicine reaches your lungs — reducing the effectiveness of your treatment. The videos and tips below demonstrate the right technique for using a spacer as well as a range of inhalers.

How to Use a Spacer

A spacer is a device that attaches to your inhaler and helps deliver medicine more effectively to your lungs. There are two techniques for using a spacer — both work well depending on your age and situation.

1. One (Deep) Breath Technique

This is the most common technique for adults in daily use. Take one slow, deep breath after pressing the inhaler, hold for 10 seconds, then breathe out slowly.

2. Four Breath Technique

This technique is recommended for children or anyone who is breathless. After pressing the inhaler into the spacer, take four normal breaths in and out through the mouthpiece.

Key Spacer Tips

  • One puff at a time: Always put only one puff of medicine into your spacer at a time. If you put in more than one puff, the medicine particles stick together and drop to the bottom of the spacer before you can breathe it in — meaning you get less of your dose.
  • Breathe in promptly: Inhale as soon as possible after pressing the puffer — don't delay.
  • Seal your lips: Ensure a firm seal around the mouthpiece to avoid medicine escaping.
  • Clean regularly: Wash your spacer monthly with warm soapy water and allow to air dry — do not towel dry as this creates static.

Types of Inhalers

There are several types of inhalers available in Australia, each with a slightly different technique:

  • Pressurised Metered Dose Inhaler (pMDI) — the most common type, often used with a spacer
  • Dry Powder Inhaler (DPI) — requires a fast, forceful breath; do not use with a spacer
  • Soft Mist Inhaler (SMI) — releases a slow-moving mist; requires slow, steady inhalation
  • Breath-Actuated Inhaler (BAI) — automatically releases medicine when you inhale

Always ask your doctor, pharmacist, or respiratory nurse to demonstrate the correct technique for your specific device.
