VDR-IV Summary
The article primarily discusses the background of HFPV, its mechanisms and functions, the components of the VDR-4, as well as nursing care considerations for patients receiving HFPV. After providing a background on its clinical use and the basic operating principles behind this particular ventilation mode, the article paid significant attention on its components- the ventilation assembly, circuits, nebulizer, and ventilation monitoring unit- in order to fully comprehend how the ventilator increases oxygenation and ventilation.
The Phasitron, which serves as the ventilation valve assembly in the VDR-4, uses a high-pressure circuit to allow a spring-controlled venturi body to move back and forth in a percussive manner and provide laminar airflow
