A patient having an acute,severe asthma exacerbation is intubated and set up on volume-controlled continuous mandatory ventilation (VC-CMV).To ensure volume delivery at the lowest peak pressure while providing for better air distribution,which flow wave form should be used?

Question

In patients with high airway resistance (R_aw),the descending pattern is more likely to deliver a set tidal volume (V_T)at a lower pressure and provide for better distribution of air through the lung than a constant or an accelerating flow.
