High-frequency jet ventilation (HFJV) minimizes movement of the thorax and abdomen and facilitates surgical procedures where even slight motion from spontaneous or intermittent positive pressure ventilation may significantly affect the duration and success of the procedure (for example atrial fibrillation ablation).

High-frequency oscillatory ventilation (HFOV) is a rescue maneuver for failed conventional mechanical ventilation. It utilizes the Taylor augmented dispersion of gases through a simple circuit in which bias flow delivers small tidal volumes for patients with acute respiratory distress syndrome (ARDS) and other medical conditions [1 – 4].

传统意义上的、目前被确认的能导致急、慢性肝炎的肝炎病毒只有HAV, HBV, HCV, HDV和HEV。其中HAV和HEV，也就是甲肝和戊肝，是粪口途径传播，HBV, HCV和HDV是血液/性接触传播，HDV只能在HBV感染的基础上感染。 90年代，陆续有团队开始宣称发现了新的肝炎病毒。 比如1994年，有研究者发表论文称在有肝炎症状的法国人的粪便中发现了直径27-37nm的病毒，认为这是一种非甲、非戊型的粪口途径传播的肝炎病毒，在接种的恒河猴模型中，能在试验动物的肝 …

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 spac …

High-frequency ventilation (HFV) has progressed over the last thirty years from its initial status as a novel ventilatory tool, to become a routine ventilatory strategy. High-frequency ventilation comprises several different modalities including high-frequency positive pressure ventilation, high frequency flow interruption,

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]

The term high-frequency ventilation (HFV) summarizes different techniques of ventilation with a ventilator frequency of more than 60 breaths per minute, tidal volumes (V T) of equal or less than dead space, as well as lower peak airway pressure, lower transpulmonary pressure, and increased functional reserve capacity when compared with ...
