Why is airway protection ability evaluated in a daily weaning plan?

• A. Airway protection ability is evaluated to determine readiness for spontaneous breathing trials.
• B. To determine the best endotracheal tube size.
• C. To evaluate airway protection ability as part of readiness for spontaneous breathing trials.
• D. To assess cough strength.

Answer: (C)

Airway protection ability is checked because, when you start spontaneous breathing, the patient must not only move air on their own but also guard the airway and clear secretions without the help of the ventilator. This means protective reflexes like coughing and swallowing, as well as the ability to close the glottis and manage secretions, need to be intact. If airway protection is poor, the risk of aspiration, desaturation, or the need for reintubation rises during a spontaneous breathing trial. So evaluating airway protection is part of determining readiness for spontaneous breathing trials to ensure a safe transition off support.
