DP

Q: How Driving Pressure (DP) can easily be calculated on the ventilator?

Answer: DP is increasingly used as guiding target in patients with ARDS who requires Low Tidal Volume Ventilation (LTVV). There are two easy ways to calculate DP

plateau-pressure minus applied PEEP 

and/or

Tidal-Volume/compliance

A value less than 20 cm H2O, and preferably below 15 cm H2O is of benefit.
