A marginal increase in peak flow after using a metered dose inhaler suggests that the current method of medication delivery may not be fully effective for the patient. Adding a spacer to the metered dose inhaler improves the technique of inhalation.

A spacer allows for a better coordination between inhalation and actuation of the inhaler. It ensures that a larger amount of medication is delivered to the lungs, as the aerosol particles have more time to slow down and can be inhaled more effectively. This can be particularly beneficial for patients with airway diseases, as it can lead to improved drug deposition in the airways and better overall control of symptoms.

In this scenario, utilizing a spacer can maximize the therapeutic benefit of the medication, unless there are other contraindications or issues that would prevent its use. This aligns with best practices for ensuring that patients with respiratory conditions receive the most effective delivery of their inhalation therapy.
