How should suction be used in prolonged care?

• A. Suction is not needed in PCC.
• B. Clear secretions and debris as needed to maintain ventilation without delaying evacuation.
• C. Suction should be used constantly every few seconds.
• D. Only suction after evacuation is completed.

Answer: (B)

Suction in prolonged care is about keeping the airway clear to maintain ventilation, but only as needed and without slowing the move to definitive care. The goal is to remove secretions, debris, or vomitus that threaten airway patency so the casualty can continue breathing effectively while you arrange evacuation. Why this approach fits best: secretions and debris can quickly block the airway, especially when care is extended in the field. Clear them promptly to preserve ventilation, but avoid overdoing it. Prolonged or continuous suctioning can cause hypoxemia, mucosal injury, and unnecessary delays, which is counterproductive when the priority is rapid evacuation. Use short, controlled suction passes only as needed to restore or maintain airway patency, pausing to re-oxygenate as possible, and proceed with transport once the airway is clear. Other approaches fall short because they either assume the airway doesn’t need intervention, rely on constant suctioning, or postpone suction until after evacuation is completed—each of which risks inadequate ventilation during the waiting period.
