Volume Control Ventilation Therapy Modes
Volume Control ventilation modes deliver a prescribed inspired tidal
volume according to a set Breath Rate and a set Inspiratory Time.
Control Ventilation (CV) Mode
In Control Ventilation (CV) mode, the device delivers volume control
therapy. This mode provides only Mandatory breaths. A Mandatory
breath is delivered according to the prescribed BPM setting for the
prescribed Inspiratory Time. This also means that the ventilator
will not respond to patient effort. In this mode, the Tidal Volume is
delivered during inhalation and PEEP is delivered during exhalation.
The following illustration describes these concepts.
