From: Clinical review: Severe asthma

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

  1. 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.
