Weaning Paramater
- PaO2/FiO2 >200
- Tidal volume 5cc/kg
- RR <20
- Vital capacity 10cc/kg
- Minute ventilation. <10L/min
- FiO2 < 0.4 with pO2 > 60 and PEEP < 8
- SBP > 90 without pressors
Greater Predictive Value
- Max inspiratory pressure greater -90cmH2O female, -120cmH2O male, weaning threshold -25 cm h2o
- RSBI: rate/tidal volume < 100 min/L.
