Aw, I'm sorry for your loss of Rex, it's so hard when they die. You did the best you could, I bet.
I don't think Red can recover anymore than she already has. But she does show interests in things as well as bask, eat (sometimes, she's difficult with me at times) , poop, thermoregulate, recognize and respond. Walking she has problems with but I'm working with her on that (She uses her front legs to kinda drag herself while moving her back legs like normal). She also has some problems properly taking in air. She has to be propped up kinda on the turtle and rock to help her breath while she sleeps. Sometimes when she's gasping I'll massage her chest to help a bit. She may improve but we'll have to see in time.
One thing about beardies is that normal CPR techniques (such as placing your hands on the center of the chest, pressing deeply into the chest) do not apply, since they are obviously very different, especially their ribs and breast plate. You have to place your thumbs on the sides, about a inch from the middle of their chest, not the exact middle
.<<< that's pretty much what I did .... I could hear air going in and out (if it was quiet).... my fear is I damaged her lungs in the attempt to keep her breathing ..... And yes I tried to gently breath into her nose too .... but by then her lungs had collapsed , no more air flowing on compressions.... so thought then she was gone....
This is 2nd lizard that has died in on my chest (Lucky was the first).
Their lungs are more on the sides than center. The rest of how to do it is kinda difficult to describe, as the exact pressure you need to apply is difficult to word.
