Initial settings and management
1. Set bias flow between 25 to 40 LPM.
Patients with severe air-leak syndrome or cuff leak may require higher set Bias
Flow to achieve the desired mP
2. Set the initial mean airway pressure (mP
conventional ventilator mP
a. You may consider a recruitment maneuver first if the patient is extremely
hypoxic by applying 40 cmH
b. If oxygenation worsens, increase mP
30 minutes until the maximum setting is reached.
Note:
Oxygenation typically may worsen in the first 30 minutes of
recruitment in severe ARDS.
