II. Efficacy
III. Types
- Open tube spacers (e.g. microspacer)
- Open tube (non-valved) that extends the distance between the mouth and the Inhaler
- Inhalant is less likely to deposit on the back of the throat with risk of adverse effects (e.g. oral Thrush, voice Hoarseness)
- Valved holding chamber (e.g. Aerochamber, optichamber)
- Valved chamber that holds the medication longer in the chamber to allow for maximal absorption
- Also extends the distance between mouth and Inhaler (as with open tube spacers)
