When she died, she was only 13, so she had a young heart and other than the weight would have been pretty 'healthy' with a young persons immune system, heart, lungs etc. Her condition was not caused by injury or trauma, it was by a lack of oxygen.
So she was in a pretty good condition to begin with, so her heart could keep going for a while. As to her gut, the damage would have been caused by, again, lack of oxygen, but that would only have been for a relatively short period of time before they got her on the vent. Any damaged areas would have sloughed off (as noted a previous report). It is possible that because her gut was rested (ie no food) for a good while - 28 days whilst she was in the childrens hosp and given time to heal (it would have been receiving oxygenated blood). It could have 'healed' enough for it then to 'tolerate' feeding again.
As for the decomposing, she won't be. Her body's condition will be deteriorating, but her tissues (other than her brain) are being perfused with oxygenated blood, while her tissues are getting oxygen they won't decompose.
She will have muscle wastage, contractures of limbs and will be very prone to infections and her skin will be very friable and prone to breakdown, but she won't be decomposing in the traditional sense.
Her skin is breaking down as you can see on her fingers

The mother has apparently posted this on the wall of Jahi's room, and it'd directed at the staff according to her twitter

Along with the comments:
Marvsmisses: I have this hanging on Jahi's wall for all the nosy, gossiping *** staff members who think we don't know they gossip about us. They turn all types of colors after they read it it. Lol #peoplegossip #weknowyoudo #friendsandfamilytoo #italwayscomesbacktome #keeptalking
So it seems they aren't happy with the staff at this facility either.
