From: Regional distribution of acoustic-based lung vibration as a function of mechanical ventilation mode
Redistribution of area and vibration intensity. Relative percentage changes in area (a) and relative percentage changes in vibration intensity (b) in different lung regions between assist volume control (VC), assist pressure control (PC), and pressure support (PS) are presented as mean percentage changes ± standard error. Gray represents VC-PC, white represents VC-PS, and black represents PC-PS. The asterisks indicate p values of less than 0.05, considered to be statistically significant. The relative percentage change in area in the middle and lower regions changed significantly from VC to PC and PS modes (a). A difference in relative percentage change in vibration between VC and PS was observed in the lower lung region.
