High Frequency Oscillatory Ventilation (HFOV) James Xie, MD Pediatric Anesthesiology Fellow Stanford Children’s Health 11/18/2019

High-frequency oscillatory ventilation (HFOV) is a lung-protective strategy that can be utilized in the full spectrum of patient populations ranging from neonatal to adults with acute lung injury. HFOV is often utilized as a rescue strategy when conventional mechanical ventilation (CV) …

This article aims to review the physiologic rationale for the use of HFOV in patients with acute respiratory failure, summarize relevant bench and animal models, and discuss the potential use of HFOV as a primary and rescue mode in adults and children with severe respiratory failure.

2024年7月5日 · High Frequency Oscillation Ventilation (HFOV) is an unconventional form of mechanical ventilation that maintains lung recruitment, avoids overdistention, and does not rely on bulk flow for oxygenation and ventilation. DESCRIPTION. MECHANISM OF GAS EXCHANGE.

Evidence supporting the feasibility of high frequency oscillatory ventilation (HFOV) follows from the observation that delivering very small tidal volumes at high frequencies can overcome the need for adequate bulk gas flow in the lung.

2007年10月11日 · HFOV has been studied across all patient ranges as a lung-protective strategy for ALI/ARDS refractory to conventional ventilation. HFOV delivers a constant flow of heated, humidified gas, providing flow rates of 20 to 60 L/minute.

2025年3月13日 · Explore the key differences between High-Frequency Oscillatory Ventilation and Conventional Ventilation, including settings, applications, and outcomes.

2003年11月19日 · High frequency oscillatory ventilation (HFOV) is an alternative method of ventilation that theoretically achieves the goals of lung protective ventilation.

High frequency oscillatory ventilation (HFOV) is an alternative method of mechanical ventilation which can help a patient out in specific circumstances, and can be used as a ‘lung protective strategy’ in the management of some severe lung conditions.

High frequency oscillatory ventilation (HFOV) is an alternative form of mechanical ventilation that can be delivered on critical care units. Unlike conventional ventilation (CV), HFOV relies on the rapid delivery of tidal volumes that are smaller than dead space. Typical tidal volumes on …
