Figure 3 ED Time Versus Quartiles of Time to Diuretic by iBNP levels

The relationship between time to initial diuretic treatment and total time spent in the emergency department (ED), divided into quartiles, is shown. Each quartile of time to treatment is divided by quartiles of iBNP levels. iBNP = immunoreactive B-type natriuretic peptide; IV = intravenous.
