What are the three benefits of HFOV?
What will be an ideal response?
First it appears as though HFOV prevents the release of inflammatory chemical mediators in the lung, resulting in less lung injury than is seen with conventional ventilation. When used in conjunction with surfactant replacement therapy during the first hours of life, the incidence and severity of BPD may be reduced. The third benefit of HFOV is that when applied early to maintain ventilation with optimal lung volume, oxygenation is increased in acute stage of RDS. This improvement in oxygenation reduces the need for surfactant administration.
