A4627 Spacer bag/reservoir
Also known as: spacer, holding chamber, MDI spacer, aerosol chamber
A reservoir or spacer attachment used with metered-dose inhalers (MDI) to improve drug delivery efficiency by holding aerosolized medication in a chamber before inhalation. Reduces need for hand-breath coordination and improves medication delivery to lungs.
Clinical Context
Used to improve inhaled medication delivery, particularly in children, elderly patients, or those with coordination difficulties. Increases lung deposition from 10-20% to 60-70% compared to MDI alone.
