Brachial stun.

Caroline: The brachial artery-

Her brachial vein.

Weak and thready at the brachial.

Looks like a branch of the brachial.

Brachial artery pumps 30 liters of blood a minute.

Bullet could be lodged in the brachial plexus. That's dangerous.

Could have been too close to the brachial plexus, maybe.

If I can tie off that brachial artery...

The brachial plexus is a network of nerves.
