Describe the waveform characteristics of controlled mandatory ventilation.

What will be an ideal response?

CMV is a mode that defines the specific control, phase and conditional variables of mandatory breaths. The CMV waveforms demonstrate that each breath is a time-triggered mandatory breath and volume controlled because the flow pattern is the same each breath. Today's ventilators control flow (flow controllers), and volume is indirectly controlled. Thus, the mode is considered VCV, which means that volume and flow are held constant and pressure is allowed to fluctuate depending on the compliance and airflow resistance.
