Driving Pressure Calculator

Formula

The formula to calculate the driving pressure is:

\[ Pd = PI - PE \]

Where:

\( Pd \) is the Driving Pressure (Pa)
\( PI \) is the inspiratory hold pressure (Pa)
\( PE \) is the expiratory hold pressure (Pa)

What is Driving Pressure?

Driving pressure is the difference between the inspiratory hold pressure and the expiratory hold pressure. It is a crucial parameter in respiratory mechanics, particularly in the context of mechanical ventilation, to assess the pressure required to inflate the lungs.

Example Calculation

Let's assume the following values:

Inspiratory Hold Pressure (PI): 1500 Pa
Expiratory Hold Pressure (PE): 500 Pa

Using the formula to calculate the driving pressure:

\[ Pd = 1500 - 500 = 1000 \text{ Pa} \]

The driving pressure is 1000 Pa.
