Metered-dose inhaler with spacer demonstration for nursing students and nurses. Learn how to use a metered-dose inhaler (MDI) with a spacer.
What is metered-dose inhaler (MDI)? It’s an inhaler used to administer a set amount of medication into the lungs like bronchodilators, corticosteroids etc.
It is important to teach the patient proper technique when using MDIs, so the medication enters the lungs rather than collecting in the mouth.
It is best to administer a metered-dose inhaler with a spacer. This will ensure the medication enters the lungs and doesn’t stay in the mouth because some of these medications are irritating to the mouth (like corticosteroids).
If a spacer is not used, the open-mouth or closed-mouth technique can be used (these techniques were demonstrated in the previous video). Always teach the patient to use the method prescribed by the physician.
The spacer makes administering a metered-dose inhaler easier in that the patient doesn’t have to have perfect timing with pressing down the inhaler and breathing in at the same time (as with the other techniques).
When using a spacer with a MDI, the medication enters this chamber and allows the patient time to inhale, and this will help decrease the amount of medication left in the mouth.
