Vibration response imaging (VRI) is a novel technology that measures vibration energy generated from airflow to create a real-time structural and functional image of the respiration process. Since this new imaging technique can be performed quickly and non-invasively at the bedside, it offers potential as a real time noninvasive method of adjusting ventilatory therapy.
Mean area (pixels)
Pre-recruitment (n = 5 breaths)
After-recruitment (n = 5 breaths)
This case demonstrates a significant increase in the geographical area of vibration response images at peak inspiration after recruitment maneuver and a PEEP increase in early ARDS. This increase in VRI area correlates with improvement in oxygenation.
Increased spatial distribution of ventilation following effective recruitment has previously been demonstrated using computerized tomography. VRI may provide a rapid bedside assessment of the effectiveness of lung recruitment and PEEP setting as an alternative to computerized tomography
