The VT8000 is a pneumatic-driven, electronically controlled ventilator. The ventilator’s tidal volume range is from 2 to 4000 ml, which supports newborns and adults. In addition to the regular mode, VT8000 has an intelligent assist mode and supports the expansion of functional modules, such as lung stretch index, lung over-expansion coefficient, and dynamic lung. At the same time, it can also customize the dual-screen operation interface according to the different needs of doctors, and configure the position of each view module flexibly. The new GUI design greatly improves the visibility and controllability of the user interface.
