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 Reid vapor pressure (RVP) is frequently used as an indication of volatility of liquid hydrocarbons. The RVP is defined as the absolute pressure (i.e., psia or bar) exerted by a mixture, determined at 100 ÂºF (37.8 ÂºC) and at a vapor to liquid ratio of 4. This is different than the true vapor pressure which is defined as the pressure of a vapor in equilibrium with its condensed phase at a specific temperature.
