WebJan 1, 2009 · high-frequency oscillatory ventilation (HFOV). HFV was introduced in the early 1970s, following the experiences by Oberg and Sjöstrand. They used higher frequencies and smaller V t to eliminate the effect of respiratory variations on carotid sinus reflexes. The increase in dead-space volume was overcome by insufflating the gas …

WebFeb 19, 2024 · This model was created and validated in the elective anesthesia world. It may work well in that context. The issue is how useful this model is among patients who are being intubated because of respiratory failure – patients with deranged physiology. Most experienced critical care practitioners realize that this model doesn’t quite work.
WebOct 11, 2007 · HFOV has been studied across all patient ranges as a lung-protective strategy for ALI/ARDS refractory to conventional ventilation. How HFOV works. HFOV delivers a constant flow of heated, humidified gas, providing flow rates of 20 to 60 L/minute.
