Improving clinical outcomes; decreasing ICU hospitalization days; saving costs
VRI™ in the ICU – a unique lung status monitoring tool
Current available technologies are inadequate for quantitative monitoring of lungs fluids. Vibration Response Imaging provides immediate, regional feedback of changes in lung fluids of the critically ill patients. Early detection can improve patient outcomes and save lives.
Clinical Benefits
- Monitoring lung deterioration using a regional lung function capabilities
- Increased clinical confidence in treatment decisions.
- Aid in improving patient outcomes.
- VRI’s ability to alert consolidations in evolution (before X-rays), that may lead to pneumonia, a common complication in the ICU (research in progress).
- VRI’s ability to detect and continuously monitor changes in Extra Vascular Lung Water (EVLW) non-invasively, which affects large populations of patients in the ICU, and cause complications, long-term lung damage and increase in morbidity (research in progress).
VRI Advantages
- Radiation-free
- Non-invasive
- Continuous monitoring (24/7)
- Immediate, objective, regional feedback of changes in lung status
- Accurate quantitative and visual representation of measurements
- Simple procedure (similar to other monitoring tools)
- User friendly
- Easy to interpret
- Cost effective
On-line or Off-line
VRI™ can be used in synchronization with the mechanical ventilator but also in any situation a regional, functional image of the patient’s lung are helpful or required.
Emerging Concepts
New concepts that are now under development will enable continuous 24/7 monitoring of changes in lung density. This may help in early, non-invasive detection of VAP (Ventilation Associated Pneumonia), consolidation, congestion, and an increase in EVLW (Extra Vascular Lung Water).
