Which condition is an indication for high-frequency ventilation (HFV) in neonates?

• A. Asthma
• B. RDS
• C. Pulmonary edema
• D. Pneumonia

Answer: (B)

When the lungs are stiff and require gentle, lung-protective ventilation, high-frequency ventilation is most useful in neonates with surfactant-deficient respiratory distress syndrome. RDS causes very low lung compliance and widespread alveolar collapse, so keeping alveoli open without pushing high pressures is key. HFV delivers tiny tidal volumes at a very high rate while maintaining a steady mean airway pressure, which improves gas exchange and minimizes lung injury from overdistention or high peak pressures. The other conditions listed—neonatal asthma, pulmonary edema, and pneumonia—do not create the same noncompliant lung scenario that HFV targets as a primary treatment, so they aren’t the classic indications for HFV in neonates.
