Mandatory Ventilation Mode)
Volume-controlled mandatory breaths(VCV) are
delivered at the set rate.
After mandatory breath, the patient is free to take any
number of spontaneous breaths which are supported
by corresponding pressure in set in the rest time of IMV
cycle.
The controlled breaths are preceded by a trigger
window, which allows comfortable patient-triggered
delivery without compromising the set rate.
