Initial ventilator settings in status asthmaticus
| Setting | Recommendation |
| Mode | Pressure-controlled ventilation |
| Respiratory rate | 10–15 breaths/min |
| Tidal volume | 6–10 ml/kg |
| Minute ventilation | 8–10 L/min |
| PEEP | 0 cmH2O |
| Inspiratory/Expiratory ratio | ≥ 1:3 |
| Inspiratory flow | ≥ 100 L/min |
| FIO2 | Maintain SaO2 >90% |
| Pplat | <35 cm H2O |
| VEI | <1.4 L |
FIO2, fraction of inspired oxygen; PEEP, positive end-expiratory pressure; Pplat, end-inspiratory plateau pressure; SaO2, oxygen saturation; VEI, end-inspired volume above apneic functional residual capacity.
