This type of flow time graph is seen in which type of ventilator mode?
Correct Answer: VCV
Description: In Volume control Ventilation (VCV) there is constant inspiratory flow. The disadvantage is that inspiratory time relatively sho, and this can lead to uneven filling of alveoli. Volume control modes of ventilation By definition, in volume control modes the tidal volume is the defined variable which is used by the ventilator to give feedback to the solenoid valve circuits. As volume and flow are inextricably linked, the volume control modes are generally constant flow modes, i.e. the ventilator delivers flow which is constant, and stops this flow when the desired volume is achieved. Because pressure is not controlled or regulated in any way, the pressure waveform takes a parabolic sloping shape as the lungs distend during a breath.
