The correlation between intraosseous and arterial pressures remains unclear. This study aimed to explore this correlation at baseline and in various clinical scenarios (e.g., different heart rates, arrhythmias, asystolic arrest, and CPR). In 11 male Yorkshire pigs (73.4\u2009\u00b1\u20095.9\u00a0kg), femoral artery and tibial Intraosseous lines were placed under anesthesia. Pressures were recorded during hemodynamic interventions and cardiac arrest. Analyses included Pearson\u2019s r, Wilcoxon rank-sum test, and BVAR. Intraosseous pressure showed correlating pulsatility with arterial pressure, ranging from 9 to 71% of mean arterial pressure. Correlation was strong under normal conditions (r\u2009=\u20090.75\u20130.96, p\u2009&lt;\u20090.001) and during CPR (r\u2009=\u20090.65\u20130.99,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001), weakened during asystole (r\u2009=\u20090.26\u2009\u00b1\u20090.46,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001), and was\u00a0disrupted by epinephrine (r\u2009=\u20090.04,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001).
