ap < 0.05 indicates a significant difference in vibration intensity distribution between VC and PS modes in the lower region. 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. | |||
