p-High: APRV initial settings


Adults
  • Set p-High at the desired or target plateau pressure, typically around 20-30 cmH2O.
  • If transitioning from conventional ventilation the measured plateau pressure may be used as long as it is <>
  • Setting p-High 2-4 cmH2O above desired mean airway pressure may be used to initially set p-High. 
Pediatrics



  • Set p-High at the desired or target plateau pressure, typically around 20-30 cmH2O.
  • If transitioning from conventional ventilation the measured plateau pressure may be used as long as it is < 30. 
  • Setting p-High 2-4 cmH2O above desired mean airway pressure may be used to initially set p-High.
Neonates



  • Set p-High at the desired or target plateau pressure, typically around 10-25 cmH2O.
  • If transitioning from conventional ventilation the measured plateau pressure may be used as long as it is < 25. 
  • Setting p-High 1-2 cmH2O above desired mean airway pressure may be used to initially set p-High. 
Mean Airway Pressure & PaO2/FiO2 Ratio

The below table can be used to help set the initial p-High. Example if a patients calculated P/F ratio is only 160, then it will take a mean airway pressure of at least ~ 25 cmH2O for adequate oxygenation.
