Relationship between CO2 pattern analyzed by the distension ratio and coronary perfusion, cerebral perfusion, mean, systolic, diastolic blood pressure and carotid blood flow in pigs during cardiopulmonary resuscitation. A Coronary perfusion pressure (measured at end decompression) depending on “distension ratio.” B Cerebral perfusion pressure (mean value throughout chest compression/decompression cycles) depending on “distension ratio.” C Mean blood pressure depending on “distension ratio.” D Systolic blood pressure depending on “distension ratio.” E Diastolic blood pressure depending on “distension ratio.” F Carotid blood flow depending on “distension ratio.” Correlations were assessed using a mixed linear model. The p values are displayed. Each pig is represented by a different color
