An extension spacer is recommended for a patient using a metered-dose inhaler who has difficulty coordinating inhalation.

• A. Use a spacer on the MDI
• B. Switch to a dry powder inhaler
• C. Inhale faster
• D. Stop using inhaled medications

Answer: (A)

Using a spacer with a metered-dose inhaler helps when coordinating pressing the inhaler with breathing is difficult. The spacer holds the aerosol after you press the canister, giving you time to inhale slowly and deeply without needing perfect timing. An extension spacer adds distance and a larger chamber, which makes it easier to seal the lips around the mouthpiece, reduces powder hitting the back of the throat, and improves the amount that reaches the lungs. This method is the simplest way to improve lung delivery for someone who struggles with coordination, compared with switching to a dry powder inhaler (which still requires a strong, coordinated inhalation), trying to inhale faster (which can worsen coordination issues), or stopping inhaled medications altogether.
