6+ Free PIP Calculator: Peak Inspiratory Pressure Calculation

The determination of the maximum pressure achieved during the inspiratory phase of mechanical ventilation is a crucial aspect of respiratory management. This measurement, typically expressed in centimeters of water (cmH2O), reflects the highest pressure exerted on the airways and alveoli during each breath delivered by the ventilator. It is influenced by factors such as tidal volume, inspiratory flow rate, airway resistance, and lung compliance. For example, a higher tidal volume delivered with a rapid flow rate, in the presence of increased airway resistance (e.g., bronchospasm), will result in an elevated value.

Accurate assessment and management of this pressure are essential to minimize the risks of ventilator-induced lung injury (VILI). Elevated values can lead to barotrauma, including pneumothorax and pneumomediastinum, while excessively low values may indicate inadequate ventilation.
