  1. ap < 0.05 indicates a significant difference in area distribution among VC and PS modes in all three regions. VC to PC mean regional area differs in the mid and lower lung regions. Tables 3 and 4 and their corresponding descriptions should be interpreted side by side. PC, assist pressure control; PS, pressure support; SD, standard deviation; VC, assist volume control; ↑ = increase; ↓ = decrease.
