Essentially, the lung infection came back and she had to go back on the ventilator - she just wasn't getting enough oxygen and it wasn't the panic attacks. They aspirated fluid from one lung that had gone semi-solid and that improved things.
There are one or two other causes for concern - her blood count is very low in spite of transfusions, for example.
She had a crisis yesterday afternoon, but pulled out of it - part of the problem is, of course, that she is weak from the chemo.
I spoke to her parents this morning - she had a comfortable night and is in no immediate danger. She is sedated, but not heavily - they can wake her up and she knows her name.
More later - I am going out this pm and won't be back until late, so I will probably post with a Wednesday morning bulletin.
