She should not get preferential treatment simply because of her age. OTOH, she should never have been arbitrarily excluded simply because she was not 12 years old.
ALL persons should be on the list regardless of their age - and then ranked on a fair and equitable basis under the same set of rules.
So, a child could get an adult's lungs and an adult could get a child's lungs [if that is even possible] - but ALL recipients would be judged on an equal basis.
That is, no "cuts" in line ...
They have separate child and adult lists for a reason, a sound medical reason.
I suspect now they will now write the criteria up expressed more complexly as a minimum chest volume or capacity rather than the easier to understand and apply age criteria at their next meeting.
Or both, must be age 12 or have a chest volume of X size to qualify for an adult lung.
