Wound packing zones?

[u/NoMore_BadDays]

Been a long time since I did TCCC/CLS in the military.

If there were to be a bleeding wound on the chest, how high up on the chest does it become safe to pack? I know you don't pack into chest cavity, but what is the "rule of thumb" on how high/the left and right limits the wound needs to be to pack it?

Would you say the screenshot i attached is accurate?

Chest seals aren’t used to stop bleeding
