## About Driving Pressure Calculator (Formula)

The Driving Pressure Calculator uses the following formula to calculate the driving pressure:

**Pd = PI – PE**

Where: Pd is the driving pressure in Pascals (Pa) PI is the inspiratory hold pressure in Pascals (Pa) PE is the expiratory hold pressure in Pascals (Pa)

The driving pressure is the pressure difference between the inspiratory hold pressure and the expiratory hold pressure. The inspiratory hold pressure is the pressure at the end of inspiration, while the expiratory hold pressure is the pressure at the end of expiration.

By subtracting the expiratory hold pressure from the inspiratory hold pressure, the driving pressure can be calculated.

This formula is used in the field of respiratory mechanics and is used to evaluate the pressure and flow relationships during breathing. The driving pressure is an important parameter in the assessment of respiratory muscle function and mechanical ventilator support.
