To effectively manage secretions in patients undergoing mechanical ventilation, it is essential to utilize both humidification and suctioning. Mechanical ventilation filters, specifically the heat and moisture exchanger (HME) filters, are effective tools for capturing moisture from exhaled gas when an artificial airway is bypassing the upper airway. These HME(filters) effectively preserve the moisture recovered from the exhaled air, which is subsequently utilized in the inspiratory process to achieve humidification during subsequent breaths.
