Phlebotomy
A certification course focused on blood collection and specimen handling techniques.
Anatomy and Physiology for Blood Collection
Understanding the Circulatory System
To collect blood safely, it’s important to know about veins, arteries, and capillaries. Veins are the most common site for blood collection because they are close to the surface and have lower pressure than arteries.
Key Veins for Phlebotomy
- Median cubital vein: Found in the bend of the elbow, this is the most commonly used vein.
- Cephalic vein: Located on the thumb side of the forearm.
- Basilic vein: On the little finger side, but less preferred due to its proximity to nerves and arteries.
Physiology Basics
Blood flows in a closed system, and understanding blood pressure, flow, and vessel anatomy helps avoid complications.
Practical Considerations
Choosing the right vein and understanding the anatomy can reduce discomfort and minimize risks.
Examples
Identifying and selecting the median cubital vein for an easier and less painful blood draw.
Avoiding the basilic vein on a patient with delicate skin to prevent injury.
In a Nutshell
Knowledge of veins and blood flow is essential for safe and effective blood collection.
