Indications for HFOV When to use HFOV: 1. Persistent Pulmonary Hypertension of the Newborn 2. Meconium Aspiration Syndrome 3. Air leak syndromes: pneumothorax, pulmonary interstitial emphysema

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.

2024年10月25日 · High frequency oscillatory ventilation (HFOV) utilises rapid ventilation rates with small tidal volumes (often less than anatomical dead space) and active inspiratory AND expiratory phases.

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.

High-frequency oscillatory ventilation (HFOV) is a form of ventilatory support that delivers extremely small tidal volumes (V Ts) at very high rates and maintains a relatively constant and higher mean airway pressure (mPaw) than mechanical ventilation.

2019年5月2日 · 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) has failed.

2022年9月29日 · High-frequency ventilation (HFV) is a type of ventilation utilized when conventional ventilation fails. In this technique, the set respiratory rate greatly exceeds the normal breathing rate. In this rescue strategy, the tidal volume delivered is significantly less and can also be less than dead space ventilation. [1] .
