In Japanese Neonatal ICUs, High Frequency Oscillatory Ventilation (HFOV) is often the first-line mode for extreme preterm infants. 🍼🏥 Initial Parameters: * MAP: Set 4–5 cmH₂O above conventional ventilation (CMV) or 1.5x higher (e.g., CMV 8 → HFOV 12) to prevent alveolar collapse. * Amplitude (Delta P): Start at 20 cmH₂O; adjust based on blood gasometry or volume. * Frequency: Default 12 Hz. Use >12 Hz for RDS (low compliance) and <12 Hz for chronic lung disease (CLD). * Volume (VThf): Target 1.0–2.0 mL/kg for most. CLD cases may require 2.0–3.0 mL/kg (Babylog series). Endotracheal Tube (ETT): * 2.5 mm: Ideal for oscillation transmission. * 2.0 mm: Required for 22–23 week infants due to tracheal size. Monitor continuously for secretions. 🩺🔧 @newborn @newborn
