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.
In physiology, intrapleural pressure (also called intrathoracic pressure) refers to the pressure within the pleural cavity. Normally, the pressure within the pleural cavity is slightly less than the atmospheric pressure, in what is known as negative pressure.When the pleural cavity is damaged/ruptured and the intrapleural pressure becomes equal to or exceeds the atmospheric pressure, pneumothorax may ensue.ntrapleural pressure depends on the ventilation phase, atmospheric pressure, and the volume of the intrapleural cavity. At rest we have a negative intrapleural pressure.
