According to The Hand to Elbow Clinic, when veins are cut, they initially bleed but can typically shut themselves within a short period of time. Because the flow of blood from veins is relatively sluggish, according to Dr. Ben Kim, blood can generally be halted by applying pressure to a wound.
The Hand to Elbow Clinic explains that veins bring blood to the heart via the lungs. As a result, they often have lower pressure than arteries, making therapy less important. However, elderly individuals report greater difficulty stemming the flow of blood; elevating the wound helps to close a vein.
According to Dr. Kim, venous bleeding can be confused with arterial damage. However, arterial bleeding is not just a brighter red that flows freely, but it is also a much more uncommon and deadly injury. If only a single artery is severed, the body can frequently heal itself without incident. The Hand to Elbow Clinic warns, however, that if both of a limb’s major arteries are severed, the limb would die within four to six hours without surgical intervention. Arterial bleeding also occurs in spurts synchronised with the heartbeat, whereas venous bleeding is slow, constant, and continuous.
When a vein or artery is severed, Dr. Kim advises individuals to apply pressure until the bleeding stops entirely; layer absorbent items to halt the bleeding.
