Table 3 Systemic circulatory variables before and after reduction of the arterial carbon dioxide partial pressure (PaCO2)

From: Cerebral haemodynamics and carbon dioxide reactivity during sepsis syndrome

  Baseline Decreased PaCO2
Heart rate (1/min) 104 ± 18 108 ± 19
Mean arterial pressure (mmHg) 89 ± 15 87 ± 16
Central venous pressure (mmHg) 15 ± 5 15 ± 6
Pulmonary arterial pressure (mmHg) 26 ± 5 25 ± 5
Intrathoracic blood volume index (ml/m2) 1032 ± 202 988 ± 231
Systemic vascular resistance index (dyn/s/cm-5/m2) 899 ± 382 874 ± 358
Cardiac index (l/min/m2) 4.2 ± 1.8 4.1 ± 1.9
  1. There were no significant differences between baseline values and reduction of the PaCO2 (P < 0.05, matched pairs t test), n = 10.
