|
What is driving pressure |
Driving pressure or DP is the difference between plateau pressure (pPlat) and positive end-expiratory pressure (PEEP) and represents the tidal volume (Vt) corrected for the patient’s static compliance (CRS) |
|
|
|
Importance of driving pressure( ∆P) |
Driving pressure is significantly related to lung stress, and driving pressure higher than 15 cm H2O is associated with dangerous levels of stress. Using driving pressure as a safety limit and not just the low tidal volume and plateau pressure less than 30 cm H2O, may be a better way to adjust Vt in order to decreases cyclic or dynamic strain during mechanical ventilation.Among ventilation variables, ΔP was most strongly associated with survival. A 1-SD increment in ΔP (approximately 7 cm H2O) was associated with increased mortality |

|
What are recommendations for ARDS |
Strong recommendations : - lower tidal volumes (4-8 mL/kg predicted body weight) -lower inspiratory pressures (plateau pressure < 30 cm H2O) - prone positioning for more than 12 hours per day. Conditional recommendations : - higher positive end-expiratory pressure -recruitment maneuvers for those with moderate to severe acute respiratory distress syndromewith a P/F ratio less than 100 |
