In pressure support ventilation the breath is cycled by flow. So as the patient takes a breath in they generate an inspiratory flow which will peak at point 1 on this diagram and will then decline down the point two, which is when the ventilator will then cycle to the next breath.

Pressure support ventilation (PSV) is a flow-limited mode of spontaneous but supported ventilation when the ventilator transitions from PEEP during expiration to a higher inspiratory pressure target that is maintained until the inspiratory flow decreases to a predetermined percentage of its peak value.

The descriptions are limited to the three modes which presently may be regarded as standard in MV: volume-controlled ventilation (VCV), pressure-controlled ventilation (PCV), and pressure support ventilation (PSV). Examples of curves will be used to explore concepts in respiratory system mechanics and how to interpret patient–ventilator ...Cited by: 12

pressure-oriented ventilation modes such as BIPAP, pressure-time diagrams show either no changes, or changes which are hard to detect, as a consequence of changes in resistance and compliance of the entire system. As a general rule it can be said that the pressure curves displayed reflect the development of pressure measured in the ventilator.

In pressure controlled ventilation, the pressure limit is (usually) the plateau pressure due to the dispersion of gas in inspiration. In volume control, the pressure measured by the ventilator is the peak airway pressure, which is really the pressure at the level of the major airways.

This is the average pressure in the respiratory system over time (taking into account both inhalation and exhalation) Mean airway pressure can be understood as the area under the curve (the integral) of the pressure vs. time graph (see the figure below). Hence, maneuvers that improve mean airway pressure generally improve oxygenation (ie via alveolar recruitment).
