a Occlusion-zone-dependent changes in the mean arterial pressure (MAP) measured at the carotic artery (carotis, proximal to the occlusion) and femoral artery (femoral, distal to the occlusion). The MAP increased significantly when compared to baseline. The increase was highest during occlusion in zone 1, followed by zones 2 and 3. The MAP distal to the balloon dropped significantly when compared to baseline. The MAP decrease at the femoral artery was strongest during occlusion in zones 1 and 2, followed by 3. b Occlusion-zone-dependent changes in heart rate (beats per minute, (bpm)). Heart rate increased significantly during occlusion in zone 1, followed by zones 2 and 3
