As I mentioned on the other board part of me wants to lean towards it being ok after time. Its young and heals fast - Im just not sure how fast the damage is done.
I can't help but think if someone had an arm or leg trapped for an hour without circulation, that the arm wouldnt be lost once free'd? Tingly as hell like when I sleep on it? but comes around.. Really not sure.
I did find these in relation to human limbs:
-you have about four hours to get the injury to a vascular surgeon and get it cared for appropriately. The rule therefore is four hours. However, the common thread I see in most sources is that about an hour and a half is the longest you want to go without blood flow to a limb.
-although I could find no solid evidence on how long a limb can live without its blood supply, it appears to be about 2-4 hours (some sources say 5-8)
-Without blood supply, your limbs and extremities become unsalvageable after six to eight hours
