'Breathe in normally' inhalers or Breath Actuated inhalers are normally given to people who are struggling with a standard 'puffer'. When you breathe in, it releases your medication in a fine mist without you having to push or squeeze a trigger. Or, if you’re struggling with coordination, your health professional may recommend an MDI with a spacer.
A spacer is a kind of holding chamber for the medicine which does away with the need to closely coordinate squeezing the inhaler and inhaling the medicine. With an inhaler and spacer, the medicine can be inhaled slowly when the user is ready. Spacers also help to reduce local side-effects, such as dysphonia (a hoarse voice) or candidiasis (oral thrush) from inhaled corticosteroids.
Dry powder inhalers deliver medicine in a fine powder form, but they don’t spray out. You must do more of the work, inhaling the powdered medicine quickly and quite forcefully.
