Lead:  It is ironic that the horrors of warfare often produce advances in science. During World War II the demands of treating battlefield wounded brought about a vast improvement in the delivery of blood.

Intro: A Moment in Time with Dan Roberts.

Content: Combat surgeons in the First World War discovered that more soldiers died from loss of blood than from the physical damage of the bullets that hit them. When blood is drained from the body, arteries tend to collapse. Collapsed arteries cut off the remaining blood supply to the vital organs and as a result, the wounded go into shock. Loss of color, cold, clammy skin, often sudden death.
