Driving Pressure Formula
The following formula is used to calculate the Driving Pressure.
Pd = PI - PE
- Where Pd is the Driving Pressure (Pa)
- PI is the inspiratory hold pressure (Pa)
- PE is the expiratory hold pressure (Pa)
To calculate the driving pressure, subtract the expiratory hold pressure from the inspiratory hold pressure.
How to Calculate Driving Pressure?
The following two example problems outline how to calculate the Driving Pressure.
Example Problem #1:
- First, determine the inspiratory hold pressure (Pa). In this example, the inspiratory hold pressure (Pa) is given as 40.
- Next, determine the expiratory hold pressure (Pa). For this problem, the expiratory hold pressure (Pa) is given as 20.
- Finally, calculate the Driving Pressure using the equation above:
Pd = PI – PE
Inserting the values from above and solving the equation:
Pd = 40 – 20 = 20 (Pa)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are:
inspiratory hold pressure (Pa) = 57
expiratory hold pressure (Pa) = 8
Entering these values yields:
Pd = 57 – 8 = 49 (Pa)
