Driving Pressure Guided Mechanical Ventilation Versus Lung Protective Ventilation Among Patients Undergoing Elective Surgeries
Sponsor: Rawalpindi Medical College
Summary
Patient undergoing surgeries in general anesthesia require support of their breathing by ventilator. Different strategies can be used to manage breathing of the patient. Lung protective ventilation provides breathing at a set volume determined by patient ideal body weight, along with a set rate to maintain adequate breathing. The pressures in the lower airway are kept less than 30 cm of H20 while a pressure of 5cm of H20 is applied to prevent lung collapse. Recently to above mentioned regimen a driving pressure is added which is a difference between lower airway pressure and pressure applied to prevent lung collapse. Ventilatory settings are adjusted to keep this driving pressure less than 15 cm of H2O.

Interventions
Lung protective ventilation
The patient in this group will receive tidal volume at 6-8 ml/kg of ideal body weight with PEEP of 5 cm of H2O and plateau pressure will be kept less than 30cm of H2O.
Driving pressure guided ventilation
They will receive tidal volume of 6-8 ml/kg of ideal body weight and initial PEEP of 5 cm of water. Principal investigator will then incrementally increase PEEP by 2 cm of water till a value 15 cm of water PEEP is reached or Plateau pressure becomes equal to 30 cm of water or driving pressure starts to increase or there is change in any hemodynamics. Each incremental PEEP will last for 3 respiratory cycles before moving on to next value. PEEP value with lowest driving pressure will then be selected for the duration of surgical procedure
