Figure 1: The systolic pressure of the caudal ventral artery does not reflect the common carotid artery.
From: Pitfalls of invasive blood pressure monitoring using the caudal ventral artery in rats
(a) Actual monitor screen displaying common carotid artery (CCA) pressure (red characters, “84/50”), caudal ventral artery (CVA) pressure (red characters, “59/48”), body temperature (white characters, “37.7”), SpO2 (blue characters, “87”), anaesthetic concentration (purple characters, “1.5”), EtCO2 concentration (white characters, “20”), and respiration rate (white characters, “73”). A difference in systolic blood pressure (BP) was observed between the CCA and CVA. (b,c) Correlation between the simultaneously recorded invasive CCA pressure (red dots) and invasive CVA pressure (blue dots) in the same animal. (b: systolic blood pressure, c: diastolic blood pressure).
