What's wrong with this picture?

A man is laying on the street bleeding. Paramedics promptly show up, hook the man up to an IV and rush him to the hospital where he can be given a blood transfusion.
They get to the hospital in record time, but the man is now dead and cannot be revived. There is no reason he should have died because the paramedics arrived in plenty of time to save his life.

Why did he die?

He was a Jehovah's Witness?

No, he did not refuse help.

Wrong blood type?

Nothing to stop him?

Nope, the hospital has whatever blood type he needs.

If you mean nothing to stop him from dying, he was a young man in good health and had no history of medical problems.

Is it too early for a clue?

Are the paramedics(or 1 of them) responsible for his death?

No

Did he bleed to death?

Did he die of an existing condition?

Is there a clue in the fact they arrived at hospital in record time?

• Is there a clue in the fact they arrived at hospital in record time?

Yes, but only to show there was enough time to get to the hospital for treatment.

• Did he die of an existing condition?

No, he had no unusual medical problem (such as hemophilia)

• Did he bleed to death?

Yes. They either did not stop the bleeding (highly improbable, but an acceptable answer) or...
the patch didn't hold (or tourniquet came loose) during transport.
He had already lost blood but not enough to kill him. It was the loss of blood during transport that did him in.
This could have been due to a sloppy patch up jop, or to due faulty medical supplies, but whoever was riding in the back with the injured man should have noticed he was still bleeding, or had started bleeding again.

Did the paramedic who was not driving fail to do something he/she should have done? or, do something he/she should not have done?
