Fig. 4From: Volume infusion cooling increases end-tidal carbon dioxide and results in faster and deeper cooling during intra-cardiopulmonary resuscitation hypothermia inductionAverage coronary perfusion pressure (a) and end-tidal carbon dioxide (b) reported every 5 min. The asterisk symbol [*] represents statistical difference (p < 0.05) between the VC and NC groups, and the pound sign [#] represents statistical difference between the VC and NVC groups. Parentheses around a symbol represent a trend (p < 0.1) with the symbols keeping the same meaning. The plus sign [+] represents a comparison of the NC and NVC groupsBack to article page
