Advanced Ventilation Graph
7.1
Introduction
Nowadays, there are many ventilators that have improved. There are ventilators without screen or even touch screen, rather just the buttons or knob to set the ventilator. As the previous two chapters have talked about the basic ventilation modes and advanced ventilation modes, in this chapter, it will show those graphs of basic ventilation modes and even some of advanced ventilation modes. These basic ventilation and advanced ventilation graphs can help more to understand modes showed on the screen of mechanical ventilator. Generally, it is important for the clinician or user to understand what those graphs mean or clinician can even tell what mode the ventilator has been set by looking at those graphs. In this chapter, graphs that will be showed are graphical loops of full- controlled, assist-controlled, and spontaneous graphical loops in airway resistance and lung compliance change and graphical loops of leakage indication and upper or lower inflection. For example, in volume-controlled mode, the flow graph is often square, while in pressure-controlled mode, the pressure graph is often square. This chapter will further show and describe those graphs above.

raphical Loops of (Full/Assist) Controlled Breath G and Spontaneous Breath
There are many different graphs and loops we would usually encounter on ventilator. For example, in Fig. 7.1, it shows waveforms of volume-time and pressure-time and pressure-volume loop. The pressure-volume loop is made from those two waveforms. While in Fig. 7.2, it shows the waveforms of full-controlled breath which are volume-controlled and pressure-controlled, in Fig. 7.3, it shows their respective graphical loops.
