Assessment of the Utility of Vibration Response Imaging (VRI) in Evaluating Dyspnea Patients Presenting to the Emergency Department

For the patient with acute dyspnea in the ED, early differentiation between CHF and non-CHF
causes is essential for proper management. The capacity to triage patients quickly and
accurately has a beneficial impact upon outcome, disposition, stratification and length of
stay in the ED and required length of hospital admission.

The ability to assess pulmonary status rapidly by quantitative regional vibration technology
offers significant potential advantage for earlier diagnosis. The VRI technique may provide
a quick and accurate method of differentiating between dyspnea due to HF and dyspnea due to
pulmonary causes; thereby improving management and outcomes.

Inclusion Criteria:

- Able and willing to provide Informed Consent;

->40 years of age;

- Estimated Body Mass Index >19;

- Patient presented to the emergency department with a chief complaint of acute
dyspnea.

Exclusion Criteria:

- Patients with obvious trauma or acute anxiety as a cause of dyspnea;

- Patient has already received directed therapy in the ED and symptoms are remarkably
improved;

- Physician concern regarding possible harm to patient caused by positioning or
ambulating the patient for VRI testing;

- Intubated or mechanically ventilated;

- Acute hemodynamic or ventilator instability requiring immediate resuscitation;

- Body habitus or skin condition that might prevent the placement of the sound sensors
on the back (e.g. severe scoliosis, kyphosis, chest wall deformation, skin lesion on
the back or compression fracture);

- Hirsutism.
