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 mercury barometer is the standard instrument for atmospheric pressure measurement in weather reporting. The decrease in atmospheric pressure with height can be predicted from the barometric formula. The unit mmHg is often called torr, particularly in vacuum applications: 760 mmHg = 760 torr. For weather applications, the standard atmospheric pressure is often called 1 bar or 1000 millibars.
