Correct answer: CUse one actuation per cycle followed immediately by slow or tidal inhalation

Multiple puffs should not be discharged into a spacer together because aerosol deposits on the chamber walls and the inhaled dose becomes unreliable. The inhaler is shaken and actuated one puff at a time, with inhalation immediately after each actuation using the slow-breath or tidal-breath technique suitable for the child and device.
