Key points about nebulisers

  • A nebuliser is a compressor machine that converts liquid medication into a fine mist breathed in through a mask or mouthpiece.
  • It's used to deliver medicines to your lungs and airways. 
  • Nebulisers need regular maintenance and cleaning to be safe and effective.

A nebuliser is a compressor machine that converts liquid medication into a fine mist that you can easily breathe into your lungs. The machine has a mouthpiece or face mask that you use to breathe in the medicine for 3 to 15 minutes.

Nebulisers for asthma or COPD

  • Generally, nebulisers are not preferred for people with asthma or COPD because they deliver a high dose of medication which can increase the chance of side effects.
  • With so many improved handheld inhaler devices there is now less need for nebulisers for people with asthma or chronic obstructive pulmonary disease (COPD). For most people, a handheld inhaler device together with a spacer is just as effective as a nebuliser to get medication to your lungs.
  • Even when you're having a flare-up (exacerbation), using a spacer with your reliever medicine is as effective as, or even better than, using a nebuliser.
  • However, in some situations where the use of a handheld inhaler device isn't suitable, such as for young children or very sick people, using a nebuliser is an alternative.


Nebulisers for other wheezy lung diseases

  • In addition to bronchodilator therapy used in treating wheezy lung diseases, many other treatments can be delivered with a nebuliser to treat conditions such as cystic fibrosis, bronchiectasis and pulmonary artery hypertension.
  • Treatments include antibiotics, pulmonary vasodilators, airway hydration and mucolytics (eg, hypertonic saline, nebulized surfactant).

Nebulisers need regular maintenance to be kept thoroughly clean to prevent possible contamination. If not cleaned properly, nebulisers can harbour bacteria and fungi, leading to chest infections.

If the use of a nebuliser is recommended for a short period of time, then you may want to consider hiring one. Some pharmacies offer a nebuliser hire service, so ask your local pharmacy.

If the use of a nebuliser is recommended long-term, on an ongoing basis, then you may want to buy a nebuliser. There are different types of nebulisers on the market and the choice of nebuliser is mainly based on preference. They cost a few hundred dollars. Depending on your condition and circumstances your local hospital may be able to provide you with a nebuliser. 


Some points to consider when buying a nebuliser are:

  • Is the nebuliser suitable for the medicine you have been prescribed? Not all medications can be used with all types of nebulisers.
  • Your medical condition – depending on your condition you will need your nebulisation more or less often, and your nebulisation time will vary as well. Before choosing your nebuliser get advice about the one that best matches your needs. 
  • Is it battery operated or electrical?
  • Is it noisy or quiet?
  • Do you need to carry the nebuliser everywhere, eg, if you travel a lot? 
  • Cost.
  • What type of accessories does it need? 

A nebuliser usually comes with detailed instructions on how to use it. Here is some general guidance:

  • Place the prescribed amount of medicine into the nebuliser chamber.
  • Connect the nebuliser to the tubing and attach it to the machine.
  • Attach the mouthpiece or mask to the chamber and switch on the machine. 
  • If you're using a mouthpiece, seal your lips around it and breathe through your mouth, not your nose. If you're using a mask, place it over your mouth and nose. 
  • Don't talk while using the nebuliser.
  • Keep the nebuliser upright while in use.
  • When you no longer see a mist, which will be after 10 to 15 minutes, the treatment is finished.
  • Healthcare workers or family members may be exposed to small amounts of the medicine and may need protection.
  • A well ventilated room is recommended to limit the passing on of any virus particles if you have COVID-19 or a seasonal flu when you're using your nebuliser.
