Which statement correctly identifies the starting settings for high-weight patients as described?

• A. 5-6 Hz for weight-based high-weight patients
• B. 2.5 Hz for weight-based high-weight patients
• C. 7.0 Hz for weight-based high-weight patients
• D. 1-2 Hz for weight-based high-weight patients

Answer: (A)

Starting high-frequency ventilation in heavier infants is typically begun at a frequency of about 5–6 Hz. The idea is to use a rate high enough to keep tidal volumes small and lung-protective in larger lungs, while still allowing adequate CO2 removal. Frequencies that are too low (which produce larger tidal volumes) risk volutrauma, and frequencies that are too high can limit gas exchange by making tidal volumes too small. After initiating at 5–6 Hz, you tailor the settings based on blood gases, chest movement, and oxygenation, adjusting amplitude and mean airway pressure as needed to achieve target ventilation and oxygenation.
