Femoral artery bleeds very quickly
The femoral artery can quickly lose large amounts of blood when severed, as in the shooting death of Sean Taylor.

- Each thigh contains a femoral artery.
- The femoral artery is the major blood vessel that supplies blood to the legs.
- It is a continuation of the external iliac artery, which comes from the abdominal aorta.
- It begins in the lower abdomen and travels from the hip to the knee.
- If the femoral artery is severed, a patient could bleed to death in minutes

A gunshot to the femoral artery -- like the one suffered Monday by football star Sean Taylor -- can quickly spiral out of control, with a person losing 20 percent of his blood in a matter of minutes, doctors say.
The femoral artery runs from the abdomen to the knee, carrying blood to the lower extremities.
First responders, family members and friends said as soon as the bullet tore through Taylor's flesh, his blood began flowing.
The body contains about five liters, or about 20 cups, of blood. It is unknown how much blood Taylor, who died from his injuries Tuesday morning at Jackson Memorial Hospital, lost between when he was shot and when emergency personnel responded. Police said they received the call for help about 15 minutes after the shooting.
''When you're bleeding, the ability to control hemorrhaging is vitally important,'' Dr. David Feldbaum, chief of vascular surgery for Memorial Hospital Pembroke, said Tuesday. ``The longer he bled, the more likely he would not survive. Seconds may not matter that much, but minutes do.''
''In a matter of minutes you could lose up to two liters of blood,'' added Dr. Fahim Habib, a trauma surgeon at Jackson Memorial. ``In several minutes, you could bleed to death.''
Habib said it is possible to lose up to 20 percent of one's blood through the femoral artery, which is two to three centimeters wide.
Compounding the problem: The artery is surrounded by blood vessels, which bleed when damaged and are very difficult to repair, Feldbaum said.
''When we operate on the femoral artery we have to be very careful to control the blood vessels,'' Feldbaum says. ``The area is not localized where the bullet hit.''
Although Feldbaum did not operate on Taylor, 24, he said the Washington Redskins safety may have had other injuries besides a punctured femoral artery.
''You get injuries to other important structures like nerves and veins,'' he says. ``You won't know for sure until you get results from pathologists.''
Taylor's family has requested that his medical records remain confidential.
Had Taylor survived, there was a high chance of permanent brain damage, said family friend and attorney Richard Sharpstein.
''Before he got to the hospital, before paramedics controlled the bleeding, he lost blood that transports nutrients to vital organs. At that time you get cell death, ischemia,'' Feldbaum says.
''It has to be reversed to maintain function'' of the heart, kidneys, brain and other organs.
In top shape, Taylor who stood 6 feet, 2 inches and weighed 212 pounds, ''probably could have lost a significant amount of blood without dying,'' Feldbaum says.
``But at some point you run out, and once your brain and heart start to die, it's not a salvageable situation.''
