Which device is most appropriate for use with a ventilated patient who has thick secretions?

• A. Wick humidifier
• B. Cascade humidifier
• C. Large reservoir nebulizer
• D. Heat moisture exchanger

Answer: (A)

Thick secretions in a ventilated patient need充分 humidification to keep mucus pliable and easier to clear. A wick humidifier works by saturating inspired gas as it passes through a wetted wick, delivering near-body temperature and high humidity consistently. This helps thin secretions and improves mucociliary clearance and suction effectiveness. Other options either rely on recycled exhaled moisture (which can clog with thick mucus and increase airway resistance), deliver medications rather than continuous humidification, or may produce condensation and less stable humidity. So the wick humidifier provides the most reliable, active humidification to manage thick secretions.
