DISTRIBUTION OF VIBRATION ENERGY AMONG DIFFERENT MODES OF MECHANICAL VENTILATION

PURPOSE: Vibration response imaging (VRI) is a novel imaging device that visualizes vibration energy emitted during the respiration process. It captures and records the energy created by airflow in the lungs during the respiration process. The object of this study was to observe how lung vibration energy, a surrogate of lung airflow, shifts with changes of modes of mechanical ventilation.
