Plateau Pressure is the pressure applied to the lungs at end inspiration, with no flow occuring(why we do the insp. hold). Peak Inspiratory Pressure includes pressure due to flow. Peak Inspiratory Pressure(PIP) is a combination of the driving pressure(flow) and plateau Pressure. Plateau pressure reading includes PEEP.
The stagnation or total pressure, p_0, is the pressure measured at the point where the fluid comes to rest. It is the highest pressure found anywhere in the flowfield, and it occurs at the stagnation point. It is the sum of the static pressure (p_0), and the dynamic pressure measured far upstream.
