Dr. Walker is talking about possibilities, not known facts. All perfectly reasonable, docs consider various causes. But keep in mind that while such injuries via CPR are possible, the probability that it happened that way is near zero. (Same with "bulimia" -- the odds against it were absolutely astronomical.)
Now think a bit. Suppose it was CPR -- then we don't have a cause for Terri's collapse. Why would she need CPR, if not for the injuries shown by the bone scan? No other cause is known or even suspected.
The bone scan offers a solid explanation. It is fully consistent with all the known facts and with Occam's razor. You don't need to look further and try to evade the obvious.
I don't expect you or some of the others to be objective about this stuff, especially at this late date. That would remove all meaning from your cyberlife. I post this information just in case some clear thinker accidently gets this far in the thread.
Tooth and mouth problems, such as discolored and decalcified teeth, and sensitive, swollen, and bleeding cheeks and gums. These are caused by vitamin deficiencies and by the stomach acid that comes up with vomit.

She didn't appear to have any major dental problems until several years after Michael ordered the nurses not to clean her teeth.
On admittance to the ER the night of the original incident, the doctors would have been able to determine if bulimia was a factor by the condition of her teeth and gums.
