定量噴霧吸入器（MDI）需透過搖晃藥罐使推進劑與藥物均勻混合，以確保每次噴出的劑量一致。正確的吸入技巧包括：先呼氣、將吸嘴含緊、噴藥時緩慢深吸氣（約 3-5 秒）、憋氣 10 秒以讓藥物沉降於下呼吸道。沙丁胺醇（Albuterol）為短效支氣管擴張劑（SABA），用於緩解急性氣喘症狀（rescue medication），不建議作為固定時間預防性用藥。
Shaking the inhaler ensures proper mixing of the medication and propellant for consistent dosing. Correct technique involves exhaling fully, inhaling slowly and deeply while actuating the device, and holding the breath to allow drug deposition.
