Flow Equation:
From: | To: |
Blood flow is the volume of blood that moves through a specific area of the circulatory system per unit time. It's typically measured in milliliters per second (mL/s) and is calculated using the formula: Flow = Velocity × Area.
The calculator uses the flow equation:
Where:
Explanation: This equation calculates the volume of blood passing through a cross-section of a blood vessel per unit time.
Details: Accurate blood flow measurement is crucial for assessing cardiovascular health, diagnosing circulatory disorders, and monitoring treatment effectiveness in various medical conditions.
Tips: Enter velocity in cm/s and area in cm². All values must be valid (velocity > 0, area > 0).
Q1: What is normal blood flow velocity?
A: Normal blood flow velocity varies by vessel type and location, ranging from 10-40 cm/s in arteries and 1-10 cm/s in veins.
Q2: How is cross-sectional area determined?
A: Cross-sectional area is typically calculated using imaging techniques like ultrasound, which can measure vessel diameter.
Q3: What factors affect blood flow?
A: Blood flow is influenced by vessel diameter, blood viscosity, pressure gradients, and vascular resistance.
Q4: Are there limitations to this calculation?
A: This simplified formula assumes laminar flow and doesn't account for turbulence, vessel elasticity, or pulsatile flow patterns.
Q5: When is blood flow measurement most important?
A: Blood flow measurement is critical in assessing conditions like arterial stenosis, deep vein thrombosis, and monitoring blood supply to organs.
