Time is Key in the Emergency Department
Chronic Heart Failure vs. Chronic Obstructive Pulmonary Disease
 Over 4.5 million patients in the US alone, present themselves each year to the ED with COPD or CHF exacerbations displaying similar symptoms. Differentiating the origin of dyspnea is often difficult since physical exam findings, chest radiographs and lab tests such as BNP, can be nonspecific. The proper patient management is extremely important and can save life’s, improve throughput and reduce costs.
Know the difference
Bronchodilator therapy may have a worsening impact on cardiac function in patients with CHF and diuretics may have a worsening effect on COPD patients who are already fluid depleted!
Differentiate. Treat. Manage.
Read about how VRIxp contributes to the process of differential diagnosis at the point of care and indicates treatment progress in a non-invasive and radiation-free way (superior results to clinical judgment only; comparable results to chest x-ray and time-consuming BNP lab tests).
