Ventilator settings and limits.
| Conventional Ventilation | INTELLiVENT-ASV | |
|---|---|---|
| Ventilator Settings | ||
| etCO2 target | 4.5 to 6.0 kPa | 4.5 to 5.5 kPa |
| SpO2 target | 90 to 92% | 89 to 93% |
| Tidal volume target | 5 to 8 mL/kg PBW | 5 to 8 mL/kg PBW |
| Ventilator Limits | ||
| Maximum airway pressure | 30 cm H2O | 30 cm H2O |
| PEEP limit | ≤12 cmH2O | 5 to 12 cmH2O |
| Tidal volume alarm limit | 9 mL/kg PBW | 9 mL/kg PBW |
| Respiratory rate limit | 30 per min | 30 per min |
| FiO2 upper limit | 0.60 | 0.60 |
Abbreviations: etCO2, end-tidal carbon dioxide; SpO2, peripheral oxygen saturation; PEEP, positive end expiratory pressure; FiO2, fraction of inspired oxygen. With INTELLiVENT-ASV, the target ranges for etCO2 and SpO2 are pre-specified and set automatically; when a certain target is chosen, the lower and upper limits of the target ranges are 0.5 kPa under and above the target of 5 kPa for etCO2, and 2% around the 91% for SpO2.
