Which statement is true about communication for a patient on mechanical ventilation after CABG?

• A. Inform patient they will not be able to talk while hooked up to the ventilator
• B. They can talk normally
• C. They can write messages
• D. Communication is not affected

Answer: (A)

When a patient is on mechanical ventilation after CABG, speaking is not possible because the endotracheal tube sits through the vocal cords and the ventilator circuit controls airflow, preventing normal phonation. The patient should be informed upfront that talking isn’t possible while the tube is in place, so they’re not surprised or frustrated. To communicate effectively, use nonverbal and written methods: a whiteboard or paper and pen for messages, picture boards, finger or hand signals, or blinking for yes/no. These approaches help the patient participate in care, reduce anxiety, and support safe cooperation during the weaning process. If a tracheostomy is later placed and a speaking valve is appropriate, speech may become possible, but during ongoing endotracheal ventilation the primary reality is that speech cannot occur.
