SUMMARY
The velocity of blood through the aorta can reach peak values of approximately 100 cm/s, influenced by factors such as body orientation and metabolic state. Cardiac output, typically around 5 L/min, can be converted to velocity by dividing the flow rate by the cross-sectional area of the aorta. However, the aorta's radius is variable due to its distensibility and the pulsatile nature of blood flow, complicating precise calculations. Understanding these dynamics is essential for designing ultrasound probes that measure blood velocity accurately.
PREREQUISITES
- Understanding of cardiac output and its calculation (stroke volume x heart rate)
