Figure 4.

Blood temperature (A), heart rate (B), and mean arterial blood pressure (C) in rats following a cardiac arrest and cardiopulmonary resuscitation. Animals were treated with DHC (0.65 mg/kg/hr) and with atropine (5 mg/kg, red line) or without atropine (green line) as pre-treatment. Statistics: We observed no effect of atropine on any of the measured parameters by comparison with a 2-way ANOVA followed by Bonferroni post-test (p = ns). Values are expressed as average ± SE, with n = 4 per group, see Methods for further details.
