Figure 2: Comparison of systolic pressure discrepancies under various conditions.
From: Pitfalls of invasive blood pressure monitoring using the caudal ventral artery in rats
The differences in systolic ABP measured in the HwTw (both head and tail kept warm), HcTw (head cool, tail warm), HwTc (head warm, tail cool), and bleeding groups were 10.8 ± 7.42 mmHg, 14.0 ± 13.7 mmHg, 25.2 ± 20.2 mmHg, and 22.9 ± 13.8 mmHg, respectively. Although no significant difference was observed in the discrepancies between the HwTw and HcTw groups, a significant difference in pressure discrepancies was found between the HwTw and HwTc groups (P = 0.0004). Similarly, a significant difference was observed between the HwTw and bleeding groups (P < 0.0001). x-axis: time (minutes), y-axis: differences in systolic arterial blood pressure (mmHg), CCA: common carotid artery, CVA: caudal ventral artery.
