Asthma and nebulisation

Are you or your child using a nebuliser to help control your asthma? Then read on.

A nebuliser is a machine that converts certain medicines from liquid form into a mist that you can inhale into your lungs. Nebulisation can be used in moderate and severe asthma attacks.

The purpose of a nebuliser is similar to that of an asthma inhaler. They’re often used in young children who struggle with their technique or when someone is too ill to use their hand-held device.

Note, however, that nebulisers are about as effective as metered-dose inhalers with spacers. A spacer with 10 puffs of the reliever may be just as effective as nebulisation.

To use a nebuliser, however, breathe in slowly and deeply over 3-5 seconds, holding your breath for 10 seconds at the end of an inhalation.

Be careful of overuse and over-dependence on nebulisation. Instead, carry a spacer device with you to use in an emergency (see tips for using your spacer device).

If you don’t have a spacer on you, you can make a hole in a polystyrene cup for your inhaler pump to fit in. Place the rim of the polystyrene cup over your mouth and spray 4-10 puffs of your reliever pump into the polystyrene cup every 20 minutes for an hour. Inhale deeply through your mouth from the polystyrene cup.
