Fig. 1From: Epinephrine delivery via EpiPen® Auto-Injector or manual syringe across participants with a wide range of skin-to-muscle distancesEpinephrine plasma concentrations after administration via EpiPen or syringe at the mid-AL or distal-AL thigh. Mean epinephrine plasma concentrations after epinephrine administration via EpiPen at the mid-AL thigh (N = 35), epinephrine administration via IM syringe at the mid-AL thigh (N = 35), saline administration via IM syringe at the mid-AL thigh (N = 35), and epinephrine administration via EpiPen at the distal-AL thigh (n = 23). Error bars are the standard error of the mean. AL anterolateral, EpiPen EpiPen Auto-Injector, IM intramuscularBack to article page
