A cuffed tracheostomy tube is in place and the patient is breathing spontaneously. To evaluate if the client can tolerate cuff deflation to promote speaking and swallowing, what action should the nurse implement?

• A. Observe coughing colored sputum after drinking a small amount of colored water
• B. Check blood pressure
• C. Measure tidal volume
• D. Assess gag reflex with a tongue depressor

Answer: (A)

Assessing tolerance for cuff deflation relies on airway protection during swallowing. When the cuff is deflated, the patient must be able to protect the lower airway to prevent aspiration. Giving a small amount of colored liquid and observing for coughing lets you test this protective mechanism. If the patient swallows the dye and coughs or clears it promptly, it indicates the swallow and laryngeal closure are intact and cuff deflation may be tolerated to allow speaking and swallowing. The colored liquid helps you detect any material that might have entered the airway.

If there is no coughing or if aspiration signs occur (desaturation, increased work of breathing, or secretions suggestive of aspiration), you would pause cuff deflation and reassess before proceeding.

Other options don’t directly assess swallowing safety with a deflated cuff. Monitoring blood pressure checks perfusion but not airway protection. Measuring tidal volume measures ventilation, not the risk of aspiration during swallowing. Testing a gag reflex with a tongue depressor doesn’t reliably indicate safe swallowing with a tracheostomy and doesn’t reflect the protective airway response during the actual swallow.
