What is a notable advantage of noninvasive positive-pressure ventilation (NIV)?

• A. Preserves airway defense mechanisms
• B. Requires heavy sedation for patient comfort
• C. Is only suitable for long-term use
• D. It necessitates invasive monitoring

Answer: (A)

A notable advantage of noninvasive positive-pressure ventilation (NIV) is that it preserves airway defense mechanisms. When NIV is utilized, the patient is not intubated, which allows for the maintenance of natural airway reflexes. This means that the body's innate ability to protect itself against aspiration and maintain patency is retained. In addition, because NIV typically involves the use of a mask or nasal interface, patients can still have voluntary control over their airflow and can cough effectively to clear secretions. This preservation of airway defenses is particularly beneficial in preventing complications such as ventilator-associated pneumonia, which can occur when invasive ventilation methods are used. The other options describe aspects that do not represent advantages of NIV—heavy sedation hinders patient interaction and may lead to complications, suitability for long-term use does not reflect an advantage in the context of immediate or acute respiratory distress, and invasive monitoring is not a characteristic associated with the noninvasive approach of NIV.
