RESUMEN

La ventilación de alta frecuencia (VAF) es una alternativa para el manejo de recién nacidos con insuficiencia respiratoria severa. Se han descrito cinco modos de transporte: 1. Ventilación alveolar directa. 2. Péndulo. 3. Dispersión convectiva con perfil de velocidad asimétrico. 4. Dispersión tipo Taylor y 5. Difusión molecular. Estos modos de transporte no se excluyen uno a otro sino que interactúan. En este informe se revisan las ventajas, desventajas y los efectos cardiovasculares y del sistema nervioso central con el empleo de la VAF.
