Early Goal-Directed Therapy (Sepsis) Program
Mechanical Ventilation of ALI/ARDS
-
Target tidal volume of 6ml/kg (predicted weight) in pts with ALI/ARDS (1B)
- Consider upper limit plateau pressure of <30cm H20 and factor chest wall compliance into this decision (1C)
- Allow supranormal PaCO2 to minimize plateau pressures and tidal volumes (if needed) (1C).
- Use PEEP to avoid lung collapse at the end of expiration (1C).
- Consider laying pts in ARDS prone if at dangerous levels of FiO2, plateau pressures and positioning changes are not injurious (2C):
- Mechanically ventilated pts should have head of bed elevated to 45 degrees (1B) unless contraindicated, then put between 30 and 45 degrees (2C)
- Consider non-invasive ventilation in pts with mild to moderate hypoxemia that are hemodynamically stable, comfortable, easily arousable, able to protect airway and rapid recovery is expected (2B).
- Pulmonary artery catheters should not be used for routine monitoring in pts with ALI/ARDS (1A).
- Use a conservative fluid strategy in pts with ALI and no evidence of tissue hypoperfusion (1C).
