Correct answer: A — Reduce humidification to thicken secretions

Chest physiotherapy with manual hyperinflation is the most effective technique for mobilising and clearing secretions in tracheostomised patients. MHI increases tidal volume beyond baseline, opens atelectatic areas, and mobilises secretions towards the central airways where they can be suctioned. Nebulised saline and mucolytics are adjuncts. Adequate humidification (not reduction) is essential to prevent secretion inspissation and tube blockage.
