Table 1 Normal values: end-systolic flow velocity, end-diastolic flow velocity and diameter from the common carotid artery, the internal carotid artery and the external carotid artery

From: Focused examination of cerebral blood flow in peri-resuscitation: a new advanced life support compliant concept—an extension of the focused echocardiography evaluation in life support examination

Extracranial cerebral arteries Peak systolic flow velocity (cm/s) End-diastolic flow velocity (cm/s) Diameter (mm)
Common carotid artery 89 ± 17 26 ± 5 6.1 ± 0.8
Internal carotid artery 65 ± 10 26 ± 5 4.7 ± 0.6
External carotid artery 85 ± 18 19 ± 6 4.1 ± 0.7
