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.
Vapor pressure or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature in a closed system. The equilibrium vapor pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid. A substance with a high vapor pressure at normal temperatures is often referred to as volatile. The pressure exhibited by vapor present above a liquid surface is kn
