Marian screams in her best REALLY LOUD VOICE that she needs a Gifted Healer RIGHT NOW and she hits the emergency pager button in her vest pocket that she told the Andalite doctor she wanted to have, if she ever had a crashing patient and he wasn't right there, and then she fumbles open her supply bag.
You cannot actually do mouth-to-mouth on Andalites, due to their lack of a mouth hole, but she has the emergency life support equipment here with the oxygen setup, and the (really cool!!!) high-tech monitoring patch thingies you can slap on someone to detect right away if they have heartbeat so she doesn't need to fumble around checking for a pulse - she manages to waste one of the patches by sticking it to itself because her hands are shaking, damn it. Focus. The resuscitation equipment is fairly intuitive but also she learned to use it, like, yesterday, and she is panicking so hard right now which is not good for information retention.
(What would Lacie do what would Lacie do - she would not panic - good start, there, really - please tell me the fucking Andalite doctor is almost here–)
She gets it out and in a second Cayaldwin will have some oxygen in his lungs - someone is talking to her but it's not a Velgarth Healer so she blocks it out...
