either a chance in the flow (more sensitive, less patient effort required) or drops of
pressure in the ventilator circuit (less sensitive, more patient effort required).



  1. .Limit/control:
    Based on what limits/controls the level of support of the set mandatory breath, the 2
    traditional modes of conventional ventilations are:
    Volume controlled (VC): level of support of mandatory breath is controlled/limited
    by a preset tidal volume (Vt)
    Pressure controlled (PC): level of support of mandatory breath is
    controlled/limited by a preset peak inspiratory pressure (PIP).
    If volume is set, pressure varies.....if pressure is set, volume varies..... according to
    the compliance.....
    COMPLIANCE =  Volume /  Pressure
    Flow patterns are also different. In pressure control ventilation, the flow pattern is
    decelerating; in volume control ventilation, the flow pattern is square (constant)
