What is the role of nebulized bronchodilators and airway clearance techniques in ventilated patients?

• A. Nebulized bronchodilators and airway clearance
• B. No role in ventilation
• C. Only after extubation
• D. Only for asthma

Answer: (A)

During mechanical ventilation, airway problems like bronchospasm and mucus plugging can seriously hinder ventilation. Nebulized bronchodilators deliver medicine directly to the airways, relaxing smooth muscle and reducing airway resistance, which can improve tidal volumes, gas exchange, and overall ventilator performance. Airway clearance techniques physically mobilize and remove secretions, decrease mucus plugging, prevent atelectasis, and improve ventilation-perfusion matching, all of which support better oxygenation and easier weaning from the ventilator. These therapies are used in ventilated patients who have bronchospasm or excessive secretions and are not limited to post-extubation or to asthma alone.
