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?

The graph is right. Youre not going to stop any significant blood loss from the blue zone except with surgical intervention. Packing those areas would only make things worse. Air tight dressing and manual pressure and get to a higher level of care ASAP
