Blood gas analysis. Data obtained at baseline, after ischemia/reperfusion (IR) protocol, initial AVP infusions (AVP-initial), mean pressure of 90 mmHg (AVP-90 mmHg) and after drug withdrawal (Withdrawal) (n = 9). Cor sinus, Venous and Arterial are (%) oxygen saturation in blood obtained from the main heart vein, pulmonary artery and femoral artery, respectively. Base excess was calculated from systemic arterial blood. *Significant difference from (IR); †significant difference between (AVP-90 mmHg) and (Withdrawal).
