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 term vapor pressure usually refers to equilibrium vapor pressure, or the pressure at which the rate that particles leave the substance to form vapor equals the rate that particles reenter the substance from the vapor. Vapor pressure depends only on the temperature and the type of substance. Scientists can measure the temperature and vapor pressure of an unknown substance to help determine what it contains. Scientists usually measure vapor pressure in units of atmospheres (atm), millimeters of mercury (mm Hg), or torr.
