Using an Inhaler with a Spacer
To control asthma, you need to use your medicines the right way. Some medicines are inhaled using a device called a metered-dose inhaler (MDI). Metered-dose inhalers deliver medicine with a fine spray. You may be asked to use a spacer (holding tube) with your inhaler. The spacer helps make sure all the medicine you need goes into your lungs.
Steps for using an inhaler with a spacer
Remove the caps from the inhaler and spacer.
Shake the inhaler well and attach the spacer. If the inhaler is being used for the first time or has not been used for a while, prime it as directed by the product maker.
Spray 1 puff into the spacer by pressing down on the inhaler.
Then breathe in through your mouth as slowly and deeply as you can. This should take about 5-10 seconds. If you breathe too quickly, you may hear a whistling sound in certain spacers.
Take the spacer out of your mouth.
Hold your breath for a count of 10.
Then hold your lips together and slowly breathe out through your mouth.
If you’re prescribed more than 1 puff of medicine at a time, wait at least 30 seconds between puffs. This number may be different for different medicines. Shake the inhaler again. Then repeat steps 2 to 4.
