Peak inspiratory pressure
Encyclopedia
Peak inspiratory pressure (PIP) is the highest level of pressure applied to the lung
s during inhalation
. In mechanical ventilation
the number reflects a positive pressure in centimeters of water pressure (cmH2O). In normal breathing, it may sometimes be referred to as the maximal inspiratory pressure (MIPO), which is a negative value.
Lung
The lung is the essential respiration organ in many air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and the more complex life forms, the two lungs are located near the backbone on either side of the heart...
