After the initiation of mechanical ventilation, patients with status asthmaticus frequently develop severe dynamic hyperinflation, which is often associated with adverse hemodynamic effects. The development of dynamic hyperinflation can be minimized by delivering the lowest possible minute ventilation in the least possible time. Therefore, the initial ventilatory strategy should involve the delivery of relatively low tidal volumes (eg, 6 mL/kg) and lower respiratory rates (eg, 8-12 breaths/min) with a high inspiratory flow rate.
