Fig. 3From: Epinephrine’s effects on cerebrovascular and systemic hemodynamics during cardiopulmonary resuscitationLinear correlation and Bland-Altman agreement plots. Plots for noninvasive (DCS) versus invasive (laser Doppler) measurements of relative cerebral blood flow (rCBF). During periods of both asphyxia and cardiac arrest, comparisons with noninvasive rCBF and invasive rCBF were validated. Each study subject is represented by a unique colorBack to article page
